职位管理后端接口设计
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
PositionController
@RestController
@RequestMapping("/system/basic/pos")
public class PositionController {@AutowiredPositionsService positionsService;@GetMapping("/")public List<Position> getAllPositions(){return positionsService.getAllPositions();}}
PositionService类
@Autowired
PositionsService positionsService;
@GetMapping("/")
public List<Position> getAllPositions(){return positionsService.getAllPositions();}
PositionMapper接口
List<Position> getAllPositions();
PositionMapper.xml
<select id="getAllPositions" resultMap="BaseResultMap">select * from position;</select>
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 {@AutowiredPositionsService positionsService;@GetMapping("/")public List<Position> getAllPositions(){return positionsService.getAllPositions();}@PostMapping("/")public RespBean addPosition(@RequestBody Position position) {if (positionsService.addPosition(position) == 1) {return RespBean.ok("添加成功!");}return RespBean.err("添加失败!");}@PutMapping("/")public RespBean updatePositions(@RequestBody Position position){if(positionsService.updatePositions(position)==1){return RespBean.ok("更新成功");}return RespBean.err("更新失败");}@DeleteMapping("/{id}")public RespBean deletePositionById(@PathVariable Integer id){if(positionsService.deletePositionById(id)==1){return RespBean.ok("删除成功");}return RespBean.err("删除失败");}}
PositionService
@Service
public class PositionsService {@AutowiredPositionMapper positionMapper;public List<Position> getAllPositions() {return positionMapper.getAllPositions();}public Integer addPosition(Position position) {position.setEnabled(true);position.setCreatedate(new Date());return positionMapper.insert(position) ;}public int updatePositions(Position position) {return positionMapper.updateByPrimaryKeySelective(position);}public int 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:
