Mybatis-Plus 自定义sql

使用springboot整合mybatis-plus（自定义sql查询）

导入依赖(注意：mybatis-plus的版本要大于3.1.2，这里使用的是3.2.0，不然会报错)

pom.xml

 <!--    mybatis-plus-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.2.0</version>
        </dependency>

 

实体类

这里就不贴代码了哈，把自己需要查询的字段放到Vo中就好了。

 

mapper层

 @Select("select member.*,shipping_address.* from member left join shipping_address on member.member_id=shipping_address.member_id") IPage<UsersAddressVo> selectUserListPage(Page<UsersAddressVo> page, UsersAddressVo usersAddressVo);

 

service层

 IPage<UsersAddressVo> selectUserListPage(UsersAddressVo usersAddressVo, Integer pageNum, Integer pageSize);

 

service业务实现层

 @Override public IPage<UsersAddressVo> selectUserListPage(UsersAddressVo usersAddressVo, Integer pageNum, Integer pageSize) { Page<UsersAddressVo> iPage = new Page<UsersAddressVo>(pageNum, pageSize); IPage<UsersAddressVo> memberList = memberMapper.selectUserListPage(iPage, usersAddressVo); return memberList; }

 

controller层

    @GetMapping("/uniteList") public TableDataInfo uniteTable(UsersAddressVo usersAddressVo, @RequestParam("pageNum") Integer pageNum, @RequestParam("pageSize") Integer pageSize){ IPage<UsersAddressVo> memberIPage = memberService.selectUserListPage(usersAddressVo, pageNum, pageSize); List<UsersAddressVo> records = memberIPage.getRecords(); return getDataTable(records); }

 

本地测试

 @Test public void contextLoads() { Page<UsersAddressVo> pages=new Page<>(1,10); memberMapper.selectUserListPage(pages,null); }

 

postman测试如下：
