16.职位管理后端接口设计

作者:互联网

  1. 把Position实体类里面的createdate属性的date改成大写的Date并修改该属性的getter和setter方法
public class Position implements Serializable {
    private Integer id;
 
    /**
     * 职位
     */
    private String name;
 
    private Date createDate;
 
    private Boolean enabled;
  1. 把PositionMapper.xml里面和createdate相关的全部修改成createDate

  2. 在controller包里面新建system包,再在system包里面新建basic包,再在basic包里面创建PositionController类,在定义PositionController类的接口的时候,一定要与数据库的menu中的url地址到一致,不然会出现没有权限访问的问题

@RestController
@RequestMapping("/system/basic/pos")
public class PositionController {
 
    @Autowired
    PositionService positionService;
 
    @GetMapping("/")
    public List<Position> getAllPositions(){
        return positionService.getAllPositions();
    }
   
}

PositionService类

@Service
public class PositionService {
 
    @Autowired
    PositionMapper positionMapper;
 
    public List<Position> getAllPositions() {
        return positionMapper.getAllPositions();
    }
}

PositionMapper接口

@Repository
public interface PositionMapper {
    int deleteByPrimaryKey(Integer id);
 
    int insert(Position record);
 
    int insertSelective(Position record);
 
    Position selectByPrimaryKey(Integer id);
 
    int updateByPrimaryKeySelective(Position record);
 
    int updateByPrimaryKey(Position record);
 
    List<Position> getAllPositions();
}

PositionMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

  </insert>
  <insert id="insertSelective" parameterType="com.lqg.vhr.model.Position">

      <if test="name != null">

      </if>
      <if test="createDate != null">
        createDate,

    <trim prefix="values (" suffix=")" suffixOverrides=",">

        #{id,jdbcType=INTEGER},

      <if test="name != null">
        #{name,jdbcType=VARCHAR},
      </if>
      <if test="createDate != null">
        #{createDate,jdbcType=TIMESTAMP},
      </if>
      <if test="enabled != null">
        #{enabled,jdbcType=BIT},
      </if>
    </trim>
  </insert>
  <update id="updateByPrimaryKeySelective" parameterType="com.lqg.vhr.model.Position">
    update position
    <set>
      <if test="name != null">
        `name` = #{name,jdbcType=VARCHAR},
      </if>
      <if test="createDate != null">
        createDate = #{createDate,jdbcType=TIMESTAMP},
      </if>
      <if test="enabled != null">
        enabled = #{enabled,jdbcType=BIT},
      </if>
    </set>
    where id = #{id,jdbcType=INTEGER}
  </update>
  <update id="updateByPrimaryKey" parameterType="com.lqg.vhr.model.Position">
    update position
    set `name` = #{name,jdbcType=VARCHAR},
      createDate = #{createDate,jdbcType=TIMESTAMP},
      enabled = #{enabled,jdbcType=BIT}
    where id = #{id,jdbcType=INTEGER}
  </update>
</mapper>

打开Postman测试查询所有的position,效果如下图:

再把position的增删改三个接口也给写一下

PositionController

@RestController
@RequestMapping("/system/basic/pos")
public class PositionController {
 
    @Autowired
    PositionService positionService;
 
    @GetMapping("/")
    public List<Position> getAllPositions(){
        return positionService.getAllPositions();
    }
 
    @PostMapping("/")
    public RespBean addPosition(@RequestBody Position position){
        if (positionService.addPosition(position)==1){
         return RespBean.ok("添加成功!");
        }
        return RespBean.error("添加失败!");
    }
 
    @PutMapping("/")
    public RespBean updatePositions(@RequestBody Position position){
        if (positionService.updatePositions(position)==1){
            return RespBean.ok("修改成功!");
        }
        return RespBean.error("修改失败!");
 
    }
 
    @DeleteMapping("/{id}")
    public RespBean deletePositionById(@PathVariable Integer id){
        if(positionService.deletePositionById(id)==1){
            return RespBean.ok("删除成功!");
        }
        return RespBean.error("删除失败");
    }
}

PositionService

@Service
public class PositionService {
 
    @Autowired
    PositionMapper positionMapper;
 
    public List<Position> getAllPositions() {
        return positionMapper.getAllPositions();
    }
 
    public Integer addPosition(Position position) {
        position.setEnabled(true);
        position.setCreateDate(new Date());
        return positionMapper.insertSelective(position);
    }
 
    public Integer updatePositions(Position position) {
        return positionMapper.updateByPrimaryKeySelective(position);
    }
 
    public Integer deletePositionById(Integer id) {
        return positionMapper.deleteByPrimaryKey(id);
    }
}

PositionMapper接口和PositionMapper.xml和前面那个是一样的,测试的添加效果如下图所示:
