global error
@Data
@NoArgsConstructor
@AllArgsConstructor
public class GlobalException extends RuntimeException {
//这个是留给后面用的 什么异常自己注入
private RespBeanEnum respBeanEnum;
}
统一异常处理 @RestControllerAdvice
@RestControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(Exception.class)
public RespBean ExceptionHandler(Exception e) {
if (e instanceof GlobalException) {
GlobalException ex = (GlobalException) e;
return RespBean.error(ex.getRespBeanEnum());
} else if (e instanceof BindException) {
//校验主键 绑定异常
BindException ex = (BindException) e;
RespBean respBean = RespBean.error(RespBeanEnum.BIND_ERROR);
respBean.setMessage("参数校验异常:" + ex.getBindingResult().getAllErrors().get(0).getDefaultMessage());
return respBean;
}
return RespBean.error(RespBeanEnum.ERROR);
}
}
这里的场景是 因为手机号码校验不成功
所以是bindexception 会获得那个异常
