一.pom文件

1.ccm-server.pom


           
                
                 
                     
      
       mysql
                      
      
       mysql-connector-java
                      
      
       8.0.15
                  
                 
                     
      
       com.alibaba
                      
      
       druid-spring-boot-starter
                      
      
       1.1.23
                  
                 
                 
                     
      
       com.baomidou
                      
      
       mybatis-plus-boot-starter
                      
      
       3.2.0

dependencyManagement标签的作用是声明版本,但是不实际引入依赖,在子工程中我们引入的依赖就无需声明版本了,起到统一版本管理的作用.

2.assembly-mysql.pom


      
            
     
      mysql
             
     
      mysql-connector-java
         
        
            
     
      com.baomidou
             
     
      mybatis-plus-boot-starter
         
        
            
     
      com.alibaba
             
     
      druid-spring-boot-starter

3.server-user.pom


       
            
     
      com.ccm
             
     
      assembly-mysql
             
     
      1.0.0

二.配置文件

server:  port: 1000  #服务端口spring:  application:    name: server-user #服务名称  datasource:    username: root    password: Test2016@    url: jdbc:mysql://ip:3306/user?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=GMT%2B8&autoReconnect=true    type: com.alibaba.druid.pool.DruidDataSourcemybatis-plus:  typeAliasesPackage: com.ccm.server.user.dao.mysql.domain  #数据库实体类包  mapper-locations: classpath:mappering/*.xml #xml文件扫描

三.配置代码

package com.ccm.server.user;import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.Import;/** * @Description server-user服务启动类 * @Author ccm * @CreateTime 2020/07/04 0:50 */@MapperScan(basePackages = "com.ccm.server.user.dao.mysql.mapper")@SpringBootApplication //声明为一个启动类@Import(value = PaginationInterceptor.class)public class ServerUserApplication {
       public static void main(String[] args) {
           SpringApplication.run(ServerUserApplication.class,args);    }}

@MapperScab注解声明要扫描的mapper对象所在包

@Import注解的功能是往spring的ioc容器中注入bean,显然我们注入了一个分页拦截器.

四.代码测试

1.controller

// An highlighted blockpackage com.ccm.server.user.controller;import com.ccm.server.user.service.TestService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** *  @Description 测试控制层 *  @Author ccm *  @CreateTime 2020/07/06 14:37 */@RestController@RequestMapping(value = "test")public class TestController {
       @Autowired    private TestService testService;    /**     * @Description springboot整合mybatis-plus和druid测试     * @Author ccm     * @CreateTime 2020/7/6 14:38     * @Params []     * @Return void     */    @GetMapping(value = "test01")    public Object test01() {
           return testService.test01();    }    /**     * @Description springboot整合mybatis-plus分页插件测试     * @Author ccm     * @CreateTime 2020/7/7 14:55     * @Params []     * @Return java.lang.Object     */    @GetMapping(value = "test02")    public Object test02() {
           return testService.test02();    }}

2.service

package com.ccm.server.user.service.impl;import com.baomidou.mybatisplus.extension.plugins.pagination.Page;import com.ccm.server.user.dao.mysql.domain.TestTable;import com.ccm.server.user.dao.mysql.mapper.TestTableMapper;import com.ccm.server.user.service.TestService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import java.util.List;/** *  @Description 测试业务层实现 *  @Author ccm *  @CreateTime 2020/07/06 14:43 */@Servicepublic class TestServiceImpl implements TestService {
       @Autowired    private TestTableMapper testTableMapper;    @Override    public List
   
     test01() {
           return testTableMapper.list();    }    @Override    public Page
    
      test02() {
           Page
     
       page = new Page<>(1, 10);        List
      
        records = testTableMapper.page(page);        page.setRecords(records);        return page;    }}

3.dao

package com.ccm.server.user.dao.mysql.mapper;import com.baomidou.mybatisplus.extension.plugins.pagination.Page;import com.ccm.server.user.dao.mysql.domain.TestTable;import org.apache.ibatis.annotations.Mapper;import java.util.List;/** *  @Description testtable业务层 *  @Author ccm *  @CreateTime 2020/07/06 14:40 */@Mapperpublic interface TestTableMapper {
       List
   
     list();    List
    
      page(Page
     
       page);}

4.domain

package com.ccm.server.user.dao.mysql.domain;import lombok.Data;/** *  @Description test_table表实体类 *  @Author ccm *  @CreateTime 2020/07/06 14:42 */@Datapublic class TestTable {
       private Long id;    private String name;}
