SPRINGBOOT2配置说明
*配置方式
采用yml配置文件
BZQ-B2B2C-ADDRESS-CONSUMER
src
main
resources
application.yml
**application.yml
这个文件很简单，它只是引用各独立配置文件，个人喜欢这样管理
## include
spring:
profiles:
include: dubbo,mvc,mybatis,jdbc,log4j
MyBatis的相关配置
这个yml文件，一定要注意它的格式，每个：号都有个空格（TMD）
## MyBatis的相关配置
mybatis:
# 映射文件位置
mapper-locations: classpath:com/soukong/center/address/mapper/*.xml
# 别名扫描包
type-aliases-package: com.soukong.center.address.entity
# 输出SQL执行语句
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
map-underscore-to-camel-case: true ###开启驼峰命名
## pagehelper分页相关配置
pagehelper:
helperDialect: mysql
reasonable: true
supportMethodsArguments: true
params: count=countSql
returnPageInfo: check
MVC，说明商品，部署目录名
## 服务器端口号
spring:
mvc:
view:
prefix: /
suffix: .html
resources:
static-locations: /resources/,/static/
server:
port: 89
servlet:
context-path: /address
关于数据库参数的相关配置
## 关于数据库参数的相关配置
spring:
datasource:
name: mysql_test
type: com.alibaba.druid.pool.DruidDataSource
#druid相关配置
druid:
#监控统计拦截的filters
filters: stat
driver-class-name: com.mysql.jdbc.Driver
#基本属性
url: jdbc:mysql://localhost:3306/ware-center?characterEncoding=utf-8
username: root
password: 123456
#配置初始化大小/最小/最大
initial-size: 1
min-idle: 1
max-active: 20
#获取连接等待超时时间
max-wait: 600000
#间隔多久进行一次检测，检测需要关闭的空闲连接
time-between-eviction-runs-millis: 60000
#一个连接在池中最小生存的时间
min-evictable-idle-time-millis: 300000
validation-query: SELECT 'x'
test-while-idle: true
test-on-borrow: false
test-on-return: false
#打开PSCache，并指定每个连接上PSCache的大小。oracle设为true，mysql设为false。分库分表较多推荐设置为false
pool-prepared-statements: false
max-pool-prepared-statement-per-connection-size: 20
- Dubbo 服务提供者配置.
## Dubbo 服务提供者配置
spring:
dubbo:
appname: sample-base-service-provider
registry: zookeeper://localhost:2181
protocol: dubbo
port: 20880
- log4j
## log4j
logging:
level:
com.soukong.center: debug,info
ZooKeeper server
基本不要什么配置，注意环境中的端口要统一！

SPRINGBOOT2项目启动
SPRING启动有很多方式，我这里用Application.main()方式
// 启动类，它一定要放在最高的目录位置，我所有的东西放在com.soukong.center.address的子目录下，它就放com.soukong.center.address，如果位置不对，会完死你。
package com.soukong.center.address;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
/**
* @作者：鲍忠启
* @描述：SpringBoot主类-启动类 com.soukong.center.manage.dao
*/
@EnableDubbo //启动DUBBO
@SpringBootApplication
@ImportResource({"classpath:appCtx-provider.xml"}) //这个是配置Dubbo用的。
@MapperScan({"com.soukong.center.address.dao" }) // 扫描你的DAO类
//@MapperScan("com.chengcheng.goods.dao.sys")
public class StartAddressApplication {
public static void main(String[] args) {
SpringApplication.run(StartAddressApplication.class, args);
}
}
SPRINGBOOT2简单版本的启动类
package com.soukong.center.address;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
/**
* @作者：BZQ
* @描述：SpringBoot主类-启动类 com.soukong.center.manage.dao
*/
@SpringBootApplication
@MapperScan({"com.soukong.center.address.dao" })
public class StartAddressApplication {
public static void main(String[] args) {
SpringApplication.run(StartAddressApplication.class, args);
}
}
Spring Boot 推荐目录结构
（1）代码层的结构
根目录：com.springboot
1.工程启动类(ApplicationServer.java)置于com.springboot.build包下
2.实体类(domain)置于com.springboot.domain
3.数据访问层(Dao)置于com.springboot.repository
4.数据服务层(Service)置于com,springboot.service,数据服务的实现接口(serviceImpl)至于com.springboot.service.impl
5.前端控制器(Controller)置于com.springboot.controller
6.工具类(utils)置于com.springboot.utils
7.常量接口类(constant)置于com.springboot.constant
8.配置信息类(config)置于com.springboot.config
9.数据传输类(vo)置于com.springboot.vo
（2）资源文件的结构
根目录:src/main/resources
1.配置文件(.properties/.json等)置于config文件夹下
2.国际化(i18n))置于i18n文件夹下
3.spring.xml置于META-INF/spring文件夹下
4.页面以及js/css/image等置于static文件夹下的各自文件下
src/main/java：
主程序入口 Application，可以通过直接运行该类来 启动 Spring Boot应用
src/main/resources：
配置目录，该目录用来存放应用的一些配置信息，比如应用名、服务端口、数据库配置等。由于我们应用了Web模块，因此产生了 static目录与templates
目录，前者用于存放静态资源，如图片、CSS、JavaScript等；后者用于存放Web页面的模板文件。
src/test：
单元测试目录，生成的 ApplicationTests 通过 JUnit4实现，可以直接用运行 Spring Boot应用的测试。
application.properties/application.yml
用于存放程序的各种依赖模块的配置信息，比如 服务端口，数据库连接配置等。。。
控制层代码(controller)
BZQ-B2B2C-ADDRESS-CONSUMER工程。
package com.soukong.center.address.controller;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@Controller
@RequestMapping("/area")
public class AreaController {
@Autowired // 这个标签下面一定要有内容，不然坑死你
private AreaDubboService areaService;
/**

*/
@ResponseBody
@RequestMapping("/list")
public R list(Integer page, Integer limit){
Map map = new HashMap<>();
map.put("offset", (page - 1) * limit);
map.put("limit", limit);
//查询列表数据
List areaList = areaService.queryList(map);
int total = areaService.queryTotal(map);
PageUtils pageUtil = new PageUtils(areaList, total, limit, page);
return R.ok().put("page", pageUtil);
}
/**

@ResponseBody
@RequestMapping("/info/{areaid}")
public R info(@PathVariable("areaid") Long areaid){
AreaEntity area = (AreaEntity)areaService.queryObject(areaid);
return R.ok().put("area", area);
}
/**

@ResponseBody
@RequestMapping("/save")
public R save(@RequestBody AreaEntity area){
areaService.save(area);
return R.ok();
}
/**

@ResponseBody
@RequestMapping("/update")
public R update(@RequestBody AreaEntity area){
areaService.update(area);
return R.ok();
}
}
服务层代码（DUBBO）
