本文主要是介绍云尚办公-0.2.0，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. service层

MyBatisPlus封装了service层，只需要继承IService接口即可。并且MyBatisPlus实现了提供了接口的实现类。

package pers.beiluo.yunshangoffice.service;import com.baomidou.mybatisplus.extension.service.IService;
import pers.beiluo.yunshangoffice.model.system.SysRole;public interface SysRoleService extends IService<SysRole> {
}

package pers.beiluo.yunshangoffice.service.impl;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;
import pers.beiluo.yunshangoffice.mapper.SysRoleMapper;
import pers.beiluo.yunshangoffice.model.system.SysRole;
import pers.beiluo.yunshangoffice.service.SysRoleService;@Service
public class SysRoleServiceImpl extends ServiceImpl<SysRoleMapper, SysRole> implements SysRoleService{//在ServiceImpl中已经完成了mapper的注入//    @Autowired//    protected M baseMapper;}

//测试类
package pers.beiluo.yunshangoffice;import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import pers.beiluo.yunshangoffice.model.system.SysRole;
import pers.beiluo.yunshangoffice.service.SysRoleService;import java.util.List;@SpringBootTest
public class SysRoleServiceTest {@Autowiredprivate SysRoleService sysRoleService;}

1.1 查询测试

    //这里要注意，@MapperScan注解扫描位置要精确到mapper所在的包，不能写上一层或更上层的包，否则会报错@Testpublic void getAllTest(){List<SysRole> list = sysRoleService.list();list.forEach(System.out::println);}

在这里插入图片描述

1.2 添加测试

    @Testpublic void insertTest(){SysRole sysRole = new SysRole();sysRole.setRoleName("角色管理员2");sysRole.setRoleCode("role");sysRole.setDescription("角色管理员2");boolean save = sysRoleService.save(sysRole);System.out.println(save);System.out.println(sysRole);}

在这里插入图片描述

1.3 修改测试

    @Testpublic void updateTest(){SysRole sysRole = new SysRole();sysRole.setId(10L);sysRole.setRoleCode("roleee");boolean b = sysRoleService.updateById(sysRole);System.out.println(b);}

在这里插入图片描述

1.4 删除测试

//根据id删除@Testpublic void deleteByIdTest(){boolean b = sysRoleService.removeById(10);System.out.println(b);}

在这里插入图片描述

//批量删除@Testpublic void deleteBatchTest(){boolean b = sysRoleService.removeByIds(Arrays.asList(2, 9));System.out.println(b);}

在这里插入图片描述

1.5 条件查询

    @Testpublic void selectTest(){
//        QueryWrapper<SysRole> sysRoleQueryWrapper = new QueryWrapper<>();
//        sysRoleQueryWrapper.eq("role_code", "roleee");LambdaQueryWrapper<SysRole> sysRoleQueryWrapper = new LambdaQueryWrapper<>();sysRoleQueryWrapper.eq(SysRole::getRoleCode,"roleee");List<SysRole> list = sysRoleService.list(sysRoleQueryWrapper);list.forEach(System.out::println);}
