java 全局异常拦截

代码如下

@RestControllerAdvice(annotations = RestController.class)
@Slf4j
public class GlobalExceptionInterceptor {

    /**
     * 捕获自定义异常，返回json信息
     */
    @ExceptionHandler({MamchargeException.class})
    @ResponseBody
    public ResultVO errorHandle(MamchargeException e) throws Exception {
        return new ResultVO(null,e.getErrorCode(),e.getMsg());
    }

    @ExceptionHandler({Exception.class})
    @ResponseBody
    public ResultVO errorHandle(Exception e) throws Exception {
        log.error("系统出错：",e);
        return ResultVO.isFail();
    }
}

RestControllerAdvice 注解表示拦截那一层

ExceptionHandler 拦截什么异常类 后面的是自定义异常类
