后端接口设计

Controller

创建JobLevelController

@RestController
@RequestMapping("/system/basic/joblevel")
public class JobLevelController {
    @Autowired
    JobLevelService jobLevelService;
    @GetMapping("/")
    public List<JobLevel> getAllJobLevels(){
        return jobLevelService.getAllJobLevels();
    }
    @PostMapping("/")
    public RespBean addPosition(@RequestBody JobLevel jobLevel){
        if (jobLevelService.addJobLevel(jobLevel)==1){
            return RespBean.ok("添加成功");
        }
        return RespBean.error("添加失败");
    }
    @PutMapping("/")
    public RespBean updatePosition(@RequestBody JobLevel jobLevel){
        if (jobLevelService.updateJobLevel(jobLevel)==1){
            return RespBean.ok("更新成功");
        }
        return RespBean.error("更新失败");
    }

    @DeleteMapping("/{id}")
    public RespBean deletePositionById(@PathVariable Integer id){
        if (jobLevelService.deleteJobLevelById(id)==1){
            return RespBean.ok("删除成功");
        }
        return RespBean.error("删除失败");
    }
    @DeleteMapping("/")
    public RespBean deleteJobLevelByIds(Integer[] ids){
        if (jobLevelService.deleteJobLevelByIds(ids)==ids.length){
            return RespBean.ok("批量删除成功");
        }
        return RespBean.error("批量删除失败");
    }
}

Service

@Service
public class JobLevelService {
    @Autowired
    JobLevelMapper jobLevelMapper;

    public List<JobLevel> getAllJobLevels() {
        return jobLevelMapper.getAllJobLevels();
    }

    public Integer addJobLevel(JobLevel jobLevel) {
        jobLevel.setEnabled(true);
        jobLevel.setCreateDate(new Date());
        return jobLevelMapper.insertSelective(jobLevel);
    }

    public Integer updateJobLevel(JobLevel jobLevel) {
        return jobLevelMapper.updateByPrimaryKeySelective(jobLevel);
    }

    public Integer deleteJobLevelById(Integer id) {
        return jobLevelMapper.deleteByPrimaryKey(id);
    }

    public Integer deleteJobLevelByIds(Integer[] ids) {
        return jobLevelMapper.deleteJobLevelByIds(ids);
    }
}

Mapper

@Repository
public interface JobLevelMapper {
    int deleteByPrimaryKey(Integer id);

    int insert(JobLevel record);

    int insertSelective(JobLevel record);

    JobLevel selectByPrimaryKey(Integer id);

    int updateByPrimaryKeySelective(JobLevel record);

    int updateByPrimaryKey(JobLevel record);

    List<JobLevel> getAllJobLevels();

    Integer deleteJobLevelByIds(@Param("ids") Integer[] ids);
}

XML

<select id="getAllJobLevels" resultMap="BaseResultMap" >
    select * from joblevel;
  </select>

<delete id="deleteJobLevelByIds">
    delete from joblevel  where id in
    <foreach collection="ids" item="id" separator="," open="(" close=")">
      #{id}
    </foreach>
  </delete>
