  19.     }

异常：springboot的@Validated检测异常，没有触发afterThrowing的通知。

  1. org.springframework.web.bind.MethodArgumentNotValidException: Validation failed for argument [0] in public org.springframework.http.ResponseEntity<java.lang.Object> co.yixiang.lujia.village.rest.CellController.create(co.yixiang.lujia.village.domain.Cell) with 2 errors: [Field error in object 'cell' on field 'pid': rejected value [null]; codes [NotBlank.cell.pid,NotBlank.pid,NotBlank.java.lang.String,NotBlank]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [cell.pid,pid]; arguments []; default message [pid]]; default message [不能为空]] [Field error in object 'cell' on field 'townName': rejected value [null]; codes [NotBlank.cell.townName,NotBlank.townName,NotBlank.java.lang.String,NotBlank]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [cell.townName,townName]; arguments []; default message [townName]]; default message [不能为空]]

解决

spring对参数校验的检测也是通过切面的形式。@Validated是在通知中抛出异常的，不属于@Log标注的方法抛出的异常，因此不能触发该切面的异常通知。
