高内聚，低耦合
并行开发，提高开发的效率
如何划分？
业务层次
功能划分
重复使用
（一）、工程创建
构建工具：gradle
(1)下载网址:https://gradle.org/
(2)系统环境变量配置
（3）使用gradle -v命令查看配置是否成功
使用IDEA创建项目流程
创建模块
（二）、数据库设计
管理端
产品表
销售端：
订单表
（三）、创建产品表
create table product(
id VARCHAR(50) not null comment '产品编号',
name VARCHAR(50) not null comment '产品名称',
threshold_amount DECIMAL(15,3) not null comment '起步金额',
step_amount DECIMAL(15,3) not null comment '投资步长',

update_at datetime comment '更新时间',
update_user VARCHAR(20) comment '更新者',
PRIMARY KEY(id)
)ENGINE=INNODB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
（四）、创建订单表
create table order_t(
order_id VARCHAR(50) not null comment '订单编号',
chan_id VARCHAR(50) not null comment '渠道编号',
product_id VARCHAR(50) not null comment '产品编号',
chan_user_id VARCHAR(50) not null comment '渠道用户编号',

public void setName(String name) {
this.name = name;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public BigDecimal getThreshouldAmount() {

}
public void setRewardRate(BigDecimal rewardRate) {
this.rewardRate = rewardRate;
}
public String getMemo() {
return memo;
}
public void setMemo(String memo) {
this.memo = memo;
}
public Date getCreateAt() {
return createAt;
}
public void setCreateAt(Date createAt) {
this.createAt = createAt;

public void setCreateUser(String createUser) {
this.createUser = createUser;
}
public String getUpdateUser() {
return updateUser;
}
public void setUpdateUser(String updateUser) {
this.updateUser = updateUser;
}
}
Order类
package com.uos.entity;
import java.math.BigDecimal;
import java.util.Date;
/**
* 订单
*/
@Entity(name = "order_t")
public class Order {
@Id
private String orderId;
//渠道id
private String chanId;
private String chanUserId;
private String orderType;
private String productId;
private BigDecimal amount;
private String outerOrderId;
private String orderStatus;
private String memo;

this.createAt = createAt;
}
public Date getUpdateAt() {
return updateAt;
}
public void setUpdateAt(Date updateAt) {
this.updateAt = updateAt;
}
}
二、管理端
(一) 、添加产品
1、管理端启动类
package com.uos.manager;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* 管理端启动类
*/
@SpringBootApplication
public class ManagerApp {
public static void main(String[] args) {
SpringApplication.run(ManagerApp.class);
}
}2、数据库的连接配置application.yml
spring:
datasource:
url: jdbc:mysql://127.0.0.1:3306/manager?user=root&password=123456&useUnicode=true&characterEncoding=utf-8
jpa:
show-sql: true
server:
context-path: /manager
port: 80813、ProductRepository接口
package com.uos.manager.repositories;
import com.uos.entity.Product;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;
/**
* 产品管理
*/
public interface ProductRepository extends JpaRepository,JpaSpecificationExecutor {
} 4、ProductService产品服务类
package com.uos.manager.service;
import com.uos.entity.Product;
import com.uos.entity.enums.ProductStatus;
import com.uos.manager.repositories.ProductRepository;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.Assert;
import java.math.BigDecimal;
import java.util.Date;
/*
产品服务类
*/
@Service
public class ProductService {
private static Logger LOG = (Logger) LoggerFactory.getLogger(ProductService.class);
@Autowired
private ProductRepository repository;
public Product addProduct(Product product){
//打印日志信息
LOG.debug("创建产品，参数：{}",product);
//数据校验
checkProduct(product);
//设置默认值
setDefault(product);
//保存值
Product result = repository.save(product);
LOG.debug("创建产品，结果：{}",result);
return result;
}
/*
设置默认值：
创建时间、更新时间、投资步长、锁定期
*/
private void setDefault(Product product) {
if (product.getCreateAt() == null) {
product.setCreateAt(new Date());
}
if (product.getUpdateAt() == null) {
product.setUpdateAt(new Date());
}
if (product.getStepAmount() == null) {
product.setStepAmount(BigDecimal.ZERO);
}
if (product.getLockTerm() == null) {
product.setLockTerm(0);
}
if (product.getStatus() == null) {
product.setStatus(ProductStatus.AUDITING.name());
}
}
/*
产品数据的校验：
1.非空数据
2.收益率在0-30%以内
3.投资步长需要为整数
*/
private void checkProduct(Product product) {
Assert.notNull(product.getId(), "编号不可为空");
//其他非空校验
Assert.isTrue(BigDecimal.ZERO.compareTo(product.getRewardRate()) < 0 && BigDecimal.valueOf(30).compareTo(product.getRewardRate()) >= 0, "收益率范围错误");
Assert.isTrue(BigDecimal.valueOf(product.getStepAmount().longValue()).compareTo(product.getStepAmount()) == 0, "投资步长需为整数");
}
}5、ProductController产品控制类
package com.uos.manager.controller;
import com.uos.entity.Product;
import com.uos.manager.service.ProductService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
/**
* 产品
*/
@RestController
@RequestMapping("/products")
public class ProductController {
private static Logger LOG = (Logger) LoggerFactory.getLogger(ProductService.class);
@Autowired
private ProductService service;
@RequestMapping(value = "",method = RequestMethod.POST)
public Product addProduct(@RequestBody Product product){
LOG.info("创建产品，参数:{}",product);
Product result = service.addProduct(product);
LOG.info("创建产品，结果:{}",result);
return result;
}
}（二）、查询产品
1、查询单个产品
在ProductService中添加
/**
* 查询单个产品
*/
public Product findOne(String id){
Assert.notNull(id,"需要产品编号参数");
LOG.debug("查询单个产品,id={}",id);
Product product = repository.findOne(id);
LOG.debug("查询单个产品，结果={}",product);
return product;
}在ProductController中添加
/**
* 查询单个产品
*/
@RequestMapping(value = "/{id}",method = RequestMethod.GET )
public Product findOne(@PathVariable String id){
LOG.info("查询单个产品,id={}",id);
Product product = service.findOne(id);
LOG.info("查询单个产品，结果={}",product);
return product;
}2、分页查询
在ProductService中添加
/**
* 分页查询
*/
public Page query(List idList,
BigDecimal minRewardRate, BigDecimal maxRewardRate,
List statusList,
Pageable pageable){
LOG.debug("查询产品,idList={},minRewardRate={},maxRewardRate={},statusList={},pageable={}",idList,minRewardRate,maxRewardRate,statusList,pageable);
Specification specification = new Specification() {
@Override
public Predicate toPredicate(Root root, CriteriaQuery query, CriteriaBuilder cb) {
//获取相关的列
Expression idCol = root.get("id");
Expression rewardRateCol = root.get("rewardRate");
Expression statusCol = root.get("status");
//定义断言列表，用来生成断言
List predicates = new ArrayList<>();
//判断产品编号的情况
if (idList != null && idList.size() > 0){
predicates.add(idCol.in(idList));
}
if (BigDecimal.ZERO.compareTo(minRewardRate) < 0){
predicates.add(cb.ge(rewardRateCol,minRewardRate));
}
if (BigDecimal.ZERO.compareTo(minRewardRate) < 0){
predicates.add(cb.le(rewardRateCol,maxRewardRate));
}
//判断产品状态的情况
if (statusList != null && statusList.size() > 0){
predicates.add(statusCol.in(statusList));
}
query.where(predicates.toArray(new Predicate[0]));
return null;
}
};
Page page = repository.findAll(specification,pageable);
LOG.debug("查询产品，结果={}",page);
return page;
} 在ProductController中添加
/**
* 分页查询
*/
@RequestMapping(value = "",method = RequestMethod.GET)
public Page query(String ids, BigDecimal minRewardRate,BigDecimal maxRewardRate,
String status,@RequestParam(defaultValue = "0") int pageNum,@RequestParam(defaultValue = "10") int pageSize){
LOG.info("查询产品,ids={},minRewardRate={},maxRewardRate={},status,pageNum={},pageSize={}");
List idList = null,statusList = null;
//判断产品编号
if (!StringUtils.isEmpty(ids)){
idList = Arrays.asList(ids.split(","));
}
//判断产品状态
if (!StringUtils.isEmpty(status)){
statusList = Arrays.asList(status.split(","));
}
Pageable pageable = new PageRequest(pageNum,pageSize);
Page page = service.query(idList,minRewardRate,maxRewardRate,statusList,pageable);
LOG.info("查询产品，结果={}",page);
return page;
} 在管理端启动类上添加@EntityScan(basePackages = {"com.uos.entity"})
（三）、统一错误处理
用户友好的错误说明
统一处理，简化业务代码
异常标准化
自定义格式化时间，在manager模块下的application.yml中添加
自定义错误页面
定义MyErrorController类
package com.uos.manager.error;
import org.springframework.boot.autoconfigure.web.ErrorProperties;
import org.springframework.boot.autoconfigure.web.servlet.error.BasicErrorController;
import org.springframework.boot.autoconfigure.web.servlet.error.ErrorViewResolver;
import org.springframework.boot.web.servlet.error.ErrorAttributes;
import javax.servlet.http.HttpServletRequest;
import java.util.List;
import java.util.Map;
/**
* 自定义错误处理controller
*/
public class MyErrorController extends BasicErrorController {
public MyErrorController(ErrorAttributes errorAttributes, ErrorProperties errorProperties, List errorViewResolvers) {
super(errorAttributes, errorProperties, errorViewResolvers);
}
@Override
protected Map getErrorAttributes(HttpServletRequest request, boolean includeStackTrace) {
Map attrs = super.getErrorAttributes(request, includeStackTrace);
//去除无关的属性
attrs.remove("timestamp");
attrs.remove("status");
attrs.remove("error");
attrs.remove("exception");
attrs.remove("path");
return attrs;
}
} 定义ErrorConfiguration类 错误处理相关配置
package com.uos.manager.error;
import org.springframework.beans.factory.ObjectProvider;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.autoconfigure.condition.SearchStrategy;
import org.springframework.boot.autoconfigure.web.*;
import org.springframework.boot.autoconfigure.web.servlet.error.ErrorViewResolver;
import org.springframework.boot.web.servlet.error.ErrorAttributes;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.List;
/**
* 错误处理相关配置
*/
@Configuration
public class ErrorConfiguration {
@Bean
public MyErrorController basicErrorController(ErrorAttributes errorAttributes, ServerProperties serverProperties,
ObjectProvider> errorViewResolversProvider) {
return new MyErrorController(errorAttributes, serverProperties.getError(),
errorViewResolversProvider.getIfAvailable());
}
} 定义ErrorEnum类 错误种类
package com.uos.manager.error;
/**
* 错误种类
*/
public enum ErrorEnum {
ID_NOT_NULL("F001","编号不能为空",false),
UNKNOWN("999","未知异常",false);
private String code;
private String message;
private boolean canRetry;
ErrorEnum(String code, String message, boolean canRetry) {
this.code = code;
this.message = message;
this.canRetry = canRetry;
}
//通过编号获取异常
public static ErrorEnum getByCode(String code){
for (ErrorEnum errorEnum : ErrorEnum.values()) {
if (errorEnum.code.equals(code)){
return errorEnum;
}
}
return UNKNOWN;
}
public String getCode() {
return code;
}
public String getMessage() {
return message;
}
public boolean isCanRetry() {
return canRetry;
}
}在MyErrorController中添加相关属性
//获取错误种类
ErrorEnum errorEnum = ErrorEnum.getByCode(errorCode);
//添加相关属性
attrs.put("message",errorEnum.getMessage());
attrs.put("code",errorEnum.getCode());
attrs.put("canRetry",errorEnum.isCanRetry());新建ErrorControllerAdvice类
package com.uos.manager.error;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.HashMap;
import java.util.Map;
/**
* 统一错误处理
*/
@ControllerAdvice(basePackages = {"com.uos.manager.controller"})
public class ErrorControllerAdvice {
@ExceptionHandler(Exception.class)
@ResponseBody
public ResponseEntity handleException(Exception e){
Map attrs = new HashMap<>();
String errorCode = e.getMessage();
ErrorEnum errorEnum = ErrorEnum.getByCode(errorCode);
//添加相关属性
attrs.put("message",errorEnum.getMessage());
attrs.put("code",errorEnum.getCode());
attrs.put("canRetry",errorEnum.isCanRetry());
attrs.put("type","advice");
return new ResponseEntity(attrs, HttpStatus.INTERNAL_SERVER_ERROR);
}
}
说明：ControllerAdvice是Controller的增强
（四）、自动化测试
采用功能测试，使用JUnit框架
在util下创建JsonUtil类
package com.uos.util;
import com.fasterxml.jackson.databind.JavaType;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.IOException;
import java.text.DateFormat;
public class JsonUtil {
private static final Logger LOG = LoggerFactory.getLogger(JsonUtil.class);
private final static ObjectMapper mapper = new ObjectMapper();
static {
mapper.enable(SerializationFeature.WRITE_NULL_MAP_VALUES);
mapper.enable(SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS);
// 属性可见度只打印public
//mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
}
public static void setDateFormat(DateFormat dateFormat) {
mapper.setDateFormat(dateFormat);
}
/**
* 把Java对象转为JSON字符串
*
* @param obj the object need to transfer into json string.
* @return json string.
*/
public static String toJson(Object obj) {
try {
return mapper.writeValueAsString(obj);
} catch (IOException e) {
LOG.error("to json exception.", e);
throw new JSONException("把对象转换为JSON时出错了", e);
}
}
}
final class JSONException extends RuntimeException {
public JSONException(final String message) {
super(message);
}
public JSONException(final String message, final Throwable cause) {
super(message, cause);
}
}
在util下创建创建RestUtil类
package com.uos.util;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.web.client.RestTemplate;
import java.util.Arrays;
import java.util.List;
import java.util.Map;
public class RestUtil {
static Logger log = LoggerFactory.getLogger(RestUtil.class);
/**
* 发送post 请求
*
* @param restTemplate
* @param url
* @param param
* @param responseType
* @param
* @return
*/
public static T postJSON(RestTemplate restTemplate, String url, Object param, Class responseType) {
HttpEntity formEntity = makePostJSONEntiry(param);
T result = restTemplate.postForObject(url, formEntity, responseType);
log.info("rest-post-json 响应信息:{}", JsonUtil.toJson(result));
return result;
}
/**
* 生成json形式的请求头
*
* @param param
* @return
*/
public static HttpEntity makePostJSONEntiry(Object param) {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
headers.add("Accept", MediaType.APPLICATION_JSON_VALUE);
HttpEntity formEntity = new HttpEntity(
JsonUtil.toJson(param), headers);
log.info("rest-post-json-请求参数:{}", formEntity.toString());
return formEntity;
}
public static HttpEntity makePostTextEntiry(Map param) {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
headers.add("Accept", MediaType.APPLICATION_JSON_VALUE);
HttpEntity formEntity = new HttpEntity(
makeGetParamContent(param), headers);
log.info("rest-post-text-请求参数:{}", formEntity.toString());
return formEntity;
}
/**
* 生成Get请求内容
*
* @param param
* @param excluedes
* @return
*/
public static String makeGetParamContent(Map param, String... excluedes) {
StringBuilder content = new StringBuilder();
List excludeKeys = Arrays.asList(excluedes);
param.forEach((key, v) -> {
content.append(key).append("=").append(v).append("&");
});
if (content.length() > 0) {
content.deleteCharAt(content.length() - 1);
}
return content.toString();
}
} 编写ProductControllerTest类
测试添加产品

exceptions.add(e1);
exceptions.add(e2);
exceptions.add(e3);
ResponseErrorHandler errorHandler = new ResponseErrorHandler() {

}
@Test
public void createException(){
exceptions.forEach(product -> {

@Test
public void findOne() {
normals.forEach(product -> {
Product result = rest.getForObject(baseUrl + "/products/" + product.getId(), Product.class);
Assert.isTrue(result.getId().equals(product.getId()), "查询失败");
});
exceptions.forEach(product -> {
Product result = rest.getForObject(baseUrl + "/products/" + product.getId(), Product.class);
Assert.isNull(result, "查询失败");
});
}

}
(二)、下单功能的实现
1.订单管理
/**
* 订单管理
*/
public interface OrderRepository extends JpaRepository, JpaSpecificationExecutor {
} 2.订单服务
/**
* 订单服务
*/
@Service
public class OrderService {
@Autowired
private OrderRepository orderRepository;
@Autowired
private ProductRpcService productRpcService;
//申购订单
public Order apply(Order order){
//数据校验
checkOrder(order);
//完善订单数据
completeOrder(order);
order = orderRepository.saveAndFlush(order);
return order;
}
//完善订单数据
private void completeOrder(Order order) {
order.setOrderId(UUID.randomUUID().toString().replaceAll("-",""));
order.setOrderType(OrderType.APPLY.name());
order.setOrderStatus(OrderStatus.SUCCESS.name());
order.setUpdateAt(new Date());
}
//校验数据
private void checkOrder(Order order) {
//必填字段
Assert.notNull(order.getOuterOrderId(),"需要外部订单编号");
Assert.notNull(order.getChanId(),"需要渠道编号");
Assert.notNull(order.getChanUserId(),"需要用户编号");
Assert.notNull(order.getProductId(),"需要产品编号");
Assert.notNull(order.getAmount(),"需要购买金额");
Assert.notNull(order.getCreateAt(),"需要购买时间");
//产品是否存在及金额是否符合要求
Product product = productRpcService.findOne(order.getProductId());
Assert.notNull(product,"产品不存在");
/*
如果有起投金额，则购买金额需要大于投资金额
如果有投资步长，则超过起投金额的部分需要为投资步长的整数倍
*/
Assert.isTrue(order.getAmount().compareTo(product.getThresholdAmount()) > 0,"购买金额不正确");
}
}3.订单相关
/**
*订单相关
*/
@RestController
@RequestMapping("/order")
public class OrderController {
static Logger LOG = LoggerFactory.getLogger(OrderController.class);
@Autowired
private OrderService orderService;
/*
下单
*/
@RequestMapping(value = "/apply",method = RequestMethod.POST)
public Order apply(@RequestBody Order order){
LOG.info("申购请求:{}",order);
order = orderService.apply(order);
LOG.info("申购结果:{}",order);
return order;
}
}4.连接数据库相关配置
5.在SellerApp添加注解
@EntityScan("com.uos.entity")
6.修改时间格式
7.测试post请求
(三)、为下单添加RSA加签验签
1.添加SignText类
2.添加OrderParam类
/**
* 下单请求参数
*/
public class OrderParam implements SignText {
//渠道id
private String chanId;
private String chanUserId;
private String productId;
private BigDecimal amount;
private String outerOrderId;
private String orderStatus;
private String memo;
@JsonFormat(pattern = "YY-MM-DD HH:mm:ss")
private Date createAt;
public String getChanId() {
return chanId;
}
public void setChanId(String chanId) {
this.chanId = chanId;
}
public String getChanUserId() {
return chanUserId;
}
public void setChanUserId(String chanUserId) {
this.chanUserId = chanUserId;
}
public String getProductId() {
return productId;
}
public void setProductId(String productId) {
this.productId = productId;
}
public BigDecimal getAmount() {
return amount;
}
public void setAmount(BigDecimal amount) {
this.amount = amount;
}
public String getOuterOrderId() {
return outerOrderId;
}
public void setOuterOrderId(String outerOrderId) {
this.outerOrderId = outerOrderId;
}
public String getOrderStatus() {
return orderStatus;
}
public void setOrderStatus(String orderStatus) {
this.orderStatus = orderStatus;
}
public String getMemo() {
return memo;
}
public void setMemo(String memo) {
this.memo = memo;
}
public Date getCreateAt() {
return createAt;
}
public void setCreateAt(Date createAt) {
this.createAt = createAt;
}
}3.修改OrderController类
4.在service下添加SignService类
/**
* 签名服务
*/
@Service
public class SignService {
static Map PUBLIC_KEYS = new HashMap<>();
static {
PUBLIC_KEYS.put("1000","MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC/91UoHgGjgPKpNg2oPZKHe4U1\n" +
"Bv2pPA4h7A2WPtPWX6OhcIWXTtsZM57vlu0jIFXKYKH+aeu3Bp+d9X8a0cw50AMa\n" +
"70DOT0yr+PE5u1zyWnqqU+va/5J+jSCBx7ur4msQYhkD5RlYMVQ//AUqI5ACArIT\n" +
"B5U4FyS6gEyCjkT/ewIDAQAB");
}
/*
根据授权编号来获取公钥
*/
public String publicKey(String authId) {
return PUBLIC_KEYS.get(authId);
}
} 5.在sign下添加SignAop 类
/**
* 验签Aop
*/
@Component
//切面
@Aspect
public class SignAop {
@Autowired
private SignService signService;
@Before(value = "execution(* com.uos.seller.controller.*.*(..)) && args(authId,sign,text,..)")
public void verify(String authId,String sign,SignText text){
String publicKey = signService.publicKey(authId);
Assert.isTrue(RSAUtil.verify(text.toText(),sign,publicKey),"验签失败");
}
}(四)、对账介绍
对账流程
生成对账文件
创建verification_order表
CREATE TABLE `verification_order` (
`order_id` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '订单编号',
`chan_id` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '渠道编号',
`product_id` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '产品编号',
`chan_user_id` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '渠道用户编号',
`order_type` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '类型,APPLY:申购,REDEEM:赎回',
`outer_order_id` varchar(50) COLLATE utf8_unicode_ci NOT NULL COMMENT '外部订单编号',
`amount` decimal(15,3) NOT NULL COMMENT '金额',
`create_at` datetime DEFAULT NULL COMMENT '创建时间',
PRIMARY KEY (`order_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;创建实体类
创建VerifyRepository
/**
* 对账相关
*/
public interface VerifyRepository extends JpaRepository, JpaSpecificationExecutor {
/*
查询某段时间[start,end)某个渠道chanId的对账数据
*/
@Query(value = "select CONCAT_WS('|',order_id,outer_order_id,chan_id,chan_user_id,product_id,order_type,amount,DATE_FORMAT(create_at,'%Y-%m-%d %H:%i:%s'))\n" +
"from order_t\n" +
"where order_status = 'success' and chan_id = ?1 and create_at >= ?2 and create_at < ?3",nativeQuery = true)
List queryVerificationOrders(String chanId, Date start,Date end);
} 在service下创建相应的服务类VerifyService
/**
* 对账服务
*/
@Service
public class VerifyService {
@Autowired
private VerifyRepository verifyRepository;
//生成文件的路径
@Value("${verification.rootdir:/opt/verification}")
private String rootDir;
//定义换行符
private static String END_LINE = System.getProperty("line.separator","\n");
//定义时间
private static DateFormat DAY_FORMAT = new SimpleDateFormat("yyyy-MM-dd");
/*
生成某个渠道某天的对账文件
*/
public File makeVerificationFile(String chanId, Date day) {
File path = getPath(chanId,day);
if (path.exists()) {
return path;
}
try {
path.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
// 构造起止时间
String start_str = DAY_FORMAT.format(day);
Date start = null;
try {
start = DAY_FORMAT.parse(start_str);
} catch (ParseException e) {
e.printStackTrace();
}
Date end = new Date(start.getTime() + 24 * 60 * 60 * 1000);
List orders = verifyRepository.queryVerificationOrders(chanId,start,end);
String content = String.join(END_LINE,orders);
FileUtil.writeAsString(path,content);
return path;
}
// 获取对账文件路径
public File getPath(String chanId, Date day) {
String name = DAY_FORMAT.format(day) + "-" + chanId + ".txt";
File path = Paths.get(rootDir,name).toFile();
return path;
}
} 创建测试类
/**
*对账测试类
*/
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
//按照方法的名称字典顺序进行排序
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class VerifyTest {
@Autowired
private VerifyService verifyService;
@Test
public void makeVerificationTest() {
Date day = new GregorianCalendar(2018,11,30).getTime();
File file = verifyService.makeVerificationFile("22",day);
System.out.println(file.getAbsolutePath());
}
}效果测试
解析对账文件
创建枚举类ChanEnum
package com.uos.seller.enums;
/**
* 渠道配置信息
*/
public enum ChanEnum {
ABC("22","ABC","/opt/ABC");
private String chanId;
private String chanName;
private String ftpPath,ftpUser,ftpPwd;
private String rootDir;
public String getChanId() {
return chanId;
}
public String getChanName() {
return chanName;
}
public String getFtpPath() {
return ftpPath;
}
public String getFtpUser() {
return ftpUser;
}
public String getFtpPwd() {
return ftpPwd;
}
public String getRootDir() {
return rootDir;
}
ChanEnum(String chanId, String chanName, String rootDir) {
this.chanId = chanId;
this.chanName = chanName;
this.rootDir = rootDir;
}
/*
根据渠道编号获取渠道的配置
*/
public static ChanEnum getByChanId(String chanId) {
for (ChanEnum chanEnum : ChanEnum.values()) {
if (chanEnum.getChanId().equals(chanId)){
return chanEnum;
}
}
return null;
}
}在VerifyService添加
/*
按照顺序解析字符串创建对账订单
order_id,outer_order_id,chan_id,chan_user_id,product_id,order_type,amount,create_at
*/
public static VerificationOrder parseLine(String line) {
VerificationOrder order = new VerificationOrder();
String[] props = line.split("\\|");
order.setOrderId(props[0]);
order.setOuterOrderId(props[1]);
order.setChanId(props[2]);
order.setChanUserId(props[3]);
order.setProductId(props[4]);
order.setOrderType(props[5]);
order.setAmount(new BigDecimal(props[6]));
try {
order.setCreateAt(DATETIME_FORMAT.parse(props[7]));
} catch (ParseException e) {
e.printStackTrace();
}
return order;
}
/*
保存渠道订单数据
*/
public void saveChanOrders(String chanId,Date day) {
ChanEnum conf = ChanEnum.getByChanId(chanId);
//根据配置从ftp下载对账的对账数据
File file = getPath(conf.getRootDir(),chanId,day);
if (!file.exists()){
return;
}
String content = null;
try {
content = FileUtil.readAsString(file);
} catch (IOException e) {
e.printStackTrace();
}
String[] lines = content.split(END_LINE);
List orders = new ArrayList<>();
for (String line : lines) {
orders.add(parseLine(line));
}
verifyRepository.saveAll(orders);
}
在测试类添加测试方法
效果测试
对账功能的实现
在VerifyRepository中添加
// 长款
@Query(value = "SELECT t.`order_id` FROM order_t t LEFT JOIN verification_order v ON t.`chan_id` = ?1 AND t.`outer_order_id` = v.`order_id` WHERE v.`order_id` IS NULL AND t.create_at >= ?2 AND t.create_at < ?3",nativeQuery = true)

errors.add("长款订单号:" + String.join(",",excessOrders));
errors.add("漏单订单号:" + String.join(",",missOrders));
errors.add("不一致订单号:" + String.join(",",differentOrders));
return errors;
} 在测试类中添加
@Test
public void verifyTest() {
Date day = new GregorianCalendar(2018,11,30).getTime();
System.out.println(String.join(";", verifyService.verifyOrder("22", day)));
}效果测试
定时对账功能的实现
/**
* 定时对账任务
*/
@Component
public class VerifyTask {
@Autowired
private VerifyService verifyService;
// 生成对账文件
@Scheduled(cron = "0 0 1,3,5 * * ? ")

public void verify() {
Date yesterday = new Date(System.currentTimeMillis() - 24 * 60 * 60 * 1000);
for (ChanEnum chanEnum : ChanEnum.values()) {
verifyService.verifyOrder(chanEnum.getChanId(),yesterday);
}
}
//测试
@Scheduled(cron = "0/5 * * * * ? ")
public void hello() {
System.out.println("hello");
}
}
JPA多数据源
