message模板失败

    //处理url的参数异常
    @ExceptionHandler(ConstraintViolationException.class)
    @ResponseStatus(code = HttpStatus.BAD_REQUEST)
    @ResponseBody
    public UnifyResponse handleConstraintViolationException(HttpServletRequest request, ConstraintViolationException e){
        String errorUrl =request.getMethod()+ " " +request.getRequestURI();
//        Iterator<ConstraintViolation<?>> errors = e.getConstraintViolations().iterator();
        String message = e.getMessage(); //这里更改就行了
        UnifyResponse unifyResponse = new UnifyResponse(10001,message,errorUrl);
        return unifyResponse;

这个仔细对比下源码吧，如果课程视频讲解有误导致这里出错，可以提出来。如果课程一步步的写了，你还是有问题，应该自己检查代码
