一. 环境搭建
hrm-parent
hrm-basic-parent //项目基本模块
hrm-basic-utils //公共工具模块
hrm-basic-common //公共代码模块
hrm-support-parent //项目支撑服务
hrm-eureka-server-1010
hrm-gateway-zuul-1020
hrm-config-server-1030
hrm-systemmanage-parent
hrm-systemmanage-common //针对系统管理服务公共代码如:domain,query
hrm-systemmanage-service-2010 //针对于系统管理的微服务
二. 完成hrm-eureka-server-1010的搭建
三. 完成hrm-gateway-zuul-1020的搭建
四. 完成hrm-config-server-1030的搭建
五:完成hrm-systemmanage-service-2010的搭建
1. 导入依赖
2. 注册到注册Eureka
3. 使用代码生成器mybatis-plus完成数据字典的CRUD
在hrm-basic-parent下创建一个独立的模块mybatis-plus
导入mybatis-plus的依赖
com.baomidou
mybatis-plus-boot-starter
2.2.0
org.apache.velocity
velocity-engine-core
2.0
mysql
mysql-connector-java
- 在resources下创建配置文件mybatiesplus-config.properties
#此处为本项目src所在路径(代码生成器输出路径),注意一定是当前项目所在的目录哟
#mapper,servier,controller输出目录
OutputDir=E:/GitLocalRepository/hrm/hrm-system-parent/hrm-system-service-2010/src/main/java
#mapper.xml SQL映射文件目录
OutputDirXml=E:/GitLocalRepository/hrm/hrm-system-parent/hrm-system-service-2010/src/main/resources
#domain,query输出的目录
OutputDirBase=E:/GitLocalRepository/hrm/hrm-system-parent/hrm-system-common/src/main/java
#设置作者
author=hfy
#自定义包路径
parent=com.hanfengyi.system
#数据库连接信息
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///hrm-system
jdbc.user=root
jdbc.pwd=112334
- 在resources下创建一个templates文件夹导入query、controller的模板,对模板简单修改,保证包名的正确
模板的文件名:query.java.vm controller.java.vm
controller:
package ${package.Controller};
import ${package.Service}.${table.serviceName};
import ${package.Entity}.${entity};
import cn.itsource.hrm.query.${entity}Query;
import cn.itsource.hrm.util.AjaxResult;
import cn.itsource.hrm.util.PageList;
import com.baomidou.mybatisplus.plugins.Page;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@RestController
@RequestMapping("/${table.entityPath}")
public class ${entity}Controller {
@Autowired
public ${table.serviceName} ${table.entityPath}Service;
/**

* @param ${table.entityPath} 传递的实体
* @return Ajaxresult转换结果
*/
@RequestMapping(value="/save",method= RequestMethod.POST)
public AjaxResult save(@RequestBody ${entity} ${table.entityPath}){
try {
if(${table.entityPath}.getId()!=null){
${table.entityPath}Service.updateById(${table.entityPath});
}else{
${table.entityPath}Service.insert(${table.entityPath});
}
return AjaxResult.me();
} catch (Exception e) {
e.printStackTrace();
return AjaxResult.me().setMessage("保存对象失败!"+e.getMessage());
}
}
/**
* 删除对象信息
* @param id
* @return
*/
@RequestMapping(value="/{id}",method=RequestMethod.DELETE)
public AjaxResult delete(@PathVariable("id") Long id){
try {
${table.entityPath}Service.deleteById(id);
return AjaxResult.me();
} catch (Exception e) {
e.printStackTrace();
return AjaxResult.me().setMessage("删除对象失败!"+e.getMessage());
}
}
//获取用户
@RequestMapping(value = "/{id}",method = RequestMethod.GET)
public ${entity} get(@PathVariable("id")Long id)
{
return ${table.entityPath}Service.selectById(id);
}
/**
* 查看所有的员工信息
* @return
*/
@RequestMapping(value = "/list",method = RequestMethod.GET)
public List<${entity}> list(){
return ${table.entityPath}Service.selectList(null);
}
/**
* 分页查询数据
*
* @param query 查询对象
* @return PageList 分页对象
*/
@RequestMapping(value = "/pagelist",method = RequestMethod.POST)
public PageList<${entity}> json(@RequestBody ${entity}Query query)
{
Page<${entity}> page = new Page<${entity}>(query.getPage(),query.getRows());
page = ${table.entityPath}Service.selectPage(page);
return new PageList<${entity}>(page.getTotal(),page.getRecords());
}
}
query:
package cn.itsource.hrm.query;
/**
*
* @author ${author}
* @since ${date}
*/
public class ${table.entityName}Query extends BaseQuery{
}
PageList
package com.hanfengyi.hrm.utils;
import java.util.ArrayList;
import java.util.List;
//分页对象:easyui只需两个属性,total(总数),datas(分页数据)就能实现分页
public class PageList {
private long total;
private List rows = new ArrayList<>();
public long getTotal() {
return total;
}
public void setTotal(long total) {
this.total = total;
}
public List getRows() {
return rows;
}
public void setRows(List rows) {
this.rows = rows;
}
@Override
public String toString() {
return "PageList{" +
"total=" + total +
", rows=" + rows +
'}';
}
//提供有参构造方法,方便测试
public PageList(long total, List rows) {
this.total = total;
this.rows = rows;
}
//除了有参构造方法,还需要提供一个无参构造方法
public PageList() {
}
}

- 在hrm-systemmanage-service-2010模块中导入mybatis-plus依赖
com.alibaba
druid
1.1.11
com.baomidou
mybatis-plus-boot-starter
2.2.0
mysql
mysql-connector-java
-
对报红的代码重新在pom中导入依赖!主配置类使用注解扫描mapper,开启事务管理,使用分页插件
@SpringBootApplication @MapperScan(value = "com.hanfengyi.system.mapper") //扫描包 @EnableTransactionManagement //开启事务支持 public class SystemServer2010 { public static void main(String[] args) { SpringApplication.run(SystemServer2010.class ); } /** * 分页插件 */ @Bean public PaginationInterceptor paginationInterceptor() { return new PaginationInterceptor(); } }
在resources下创建配置文件,集成datasource数据源、mybatis-plus
eureka:
client:
serviceUrl:
defaultZone: http://localhost:1010/eureka/ #注册中心服务端的注册地址
instance:
prefer-ip-address: true #使用ip进行注册
instance-id: system-server:2010 #服务注册到注册中心的id
server:
port: 2010
#应用的名字
spring:
application:
name: system-server
#集成DataSource
datasource:
username: root
password: 112334
url: jdbc:mysql:///hrm-system
driver-class-name: com.mysql.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
#集成Mybatis-plus
mybatis-plus:
mapper-locations: classpath:com/hanfengyi/system/mapper/*Mapper.xml
- 创建一个单独存放配置文件的文件夹,用来从git远程拉取配置文件,把zuul和systemmanage注册到注册中心!
- 简单测试 启动服务访问http://localhost:2010/system/systemdictionary/list 如果能够拿到数据,表示集成成功!
五:完成hrm-course-service-2020的搭建
与hrm-systemmanage-service-2010的搭建是一样的
六:接口文档Swagger的集成
①:导入依赖
io.springfox
springfox-swagger2
2.9.2
io.springfox
springfox-swagger-ui
2.9.2
②:创建启动类
@Configuration
@EnableSwagger2
public class Swagger2 {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
//对外暴露服务的包,以controller的方式暴露,所以就是controller的包.
.apis(RequestHandlerSelectors.basePackage("com.hanfengyi.system.web.controller"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("平台服务api")
.description("平台服务接口文档说明")
.contact(new Contact("test", "", "[email protected]"))
.version("1.0")
.build();
}
}
③:测试
启动服务,访问:http://localhost:2010/swagger-ui.html
七:zuul网关整合Swagger
在zuul模块中导入依赖
io.springfox
springfox-swagger2
io.springfox
springfox-swagger-ui
创建两个配置类
SwaggerConfig
@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo());
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("人力资源平台")
.description("人力资源平台接口文档说明")
.termsOfServiceUrl("http://localhost:1020")
.contact(new Contact("test", "", "[email protected]"))
.version("1.0")
.build();
}
}
DocumentationConfig
resources.add(swaggerResource(服务名字,服务访问路径,版本号);
@Component
@Primary
public class DocumentationConfig implements SwaggerResourcesProvider {
@Override
public List get() {
List resources = new ArrayList<>();
resources.add(swaggerResource("系统管理", "/system/v2/api-docs", "2.0"));
resources.add(swaggerResource("课程管理", "/course/v2/api-docs", "2.0"));
return resources;
}
private SwaggerResource swaggerResource(String name, String location, String version) {
SwaggerResource swaggerResource = new SwaggerResource();
swaggerResource.setName(name);
swaggerResource.setLocation(location);
swaggerResource.setSwaggerVersion(version);
return swaggerResource;
}
}
