ResponseEntity的返回值用法
1.Get请求时
/**
* 查询
*
* @param name
* @return
*/
@GetMapping("/queryUserById")
public ResponseEntity queryUserById(@RequestParam("name") String name) {
OrmUserPO ormUserPO = ormUserService.queryOrmUserByName(name);
return ResponseEntity.ok(ormUserPO);
}
2.1 Post请求新增一条记录时,有返回值
return ResponseEntity.status(HttpStatus.CREATE).body();()存放返回的内容
/**
* 新增
*
* @param userVO
* @return
*/
@PostMapping("/addOrmUser")
public ResponseEntity addOrmUser(@RequestBody OrmUserVO userVO) {
OrmUserPO ormUserPO = new OrmUserPO();
//bean copyProperties(数据源，目标源)；
BeanUtils.copyProperties(userVO, ormUserPO);
return ResponseEntity.status(HttpStatus.CREATED).body(this.ormUserService.addOrmUser(ormUserPO));
}
2.2 Post请求新增一条记录时,有无回值
**return new ResponseEntity(HttpStatus.CREATED); **
/**
* 新增
*
* @param userVO
* @return
*/
@PostMapping("/addOrmUser")
public ResponseEntity addOrmUser(@RequestBody OrmUserVO userVO) {
OrmUserPO ormUserPO = new OrmUserPO();
//bean copyProperties(数据源，目标源)；
BeanUtils.copyProperties(userVO, ormUserPO);
return new ResponseEntity(HttpStatus.CREATED);
}
3.1 Delete删除请求,无返回
**return new ResponseEntity(HttpStatus.NO_CONTENT); **
/**
* 删除
*
* @param id
* @return
*/
@DeleteMapping("/deleteOrmUserById")
public ResponseEntity deleteOrmUserById(@RequestParam("id") Integer id) {
return ResponseEntity.ok(this.ormUserService.deleteOrmUser(id));
}
4.Put更新请求，无返回值
**ResponseEntity.noContent().build(); **
/**
* 修改
*
* @param ormUserPO
* @return
*/
@PutMapping("/updateUserById")
public ResponseEntity updateUserById(@RequestBody OrmUserPO ormUserPO) {
return ResponseEntity.ok(this.ormUserService.updateOrmUser(ormUserPO));
}
