spring-boot Web developers based global exception handler 3-

A, @ ControllerAdvice Notes: Write a class, plus

二、@ExceptionHandler(value=Exception.class)

       Create exception handling, methods need to add @ExceptionHandler (value = Exception.class) notes, handle exceptions in which method

Third, for example,

      We first need to throw RuntimeException at a specified point

    catch (Exception e) {
            LOGGER.error("密文加密失败"+e.getMessage(),e);
            throw new RuntimeException("密文加密失败");
        }

 /**
     * description 拦截未知的运行时异常
     *
     * @param e 1
     * @return com.usthe.bootshiro.domain.vo.Message
     */
    @ExceptionHandler(RuntimeException.class)
    @ResponseStatus(HttpStatus.OK)
    public Message notFoundException(RuntimeException e) {
        LOGGER.error("运行时异常:",e);
        return new Message().error(1111,"服务器开小差");
    }
