Spring security 自定义的AccessDeniedHandler无效，抛出AccessDeniedException 不允许访问

原因：全局异常处理比AccessDeniedHandler先捕获AccessDeniedException异常

处理办法：

在全局异常处向上抛出AccessDeniedException异常, 有AccessDeniedException捕获

    @ExceptionHandler(value =Exception.class)
    public ResultJson exceptionHandler(Exception e) throws Exception {
        //抛出AccessDeniedException异常
        if(e.getCause().equals(AccessDeniedException.class)){
            throw e;
        }
 
        log.error("未知异常！原因是:",e);
        return ResultJson.error(CommonEnum.INTERNAL_SERVER_ERROR);
    }
