web.xml 关键配置, 可以确定的是配置顺序没有问题

<!-- 安全过滤 -->

控制器代码1, 像这样加入异步处理,正常响应,但是后台报错

/**
	 * 分页查询
	 * 
	 * @param queryVo
	 * @return Pagination<DynamicformVo>
	 */
	@RequestMapping("queryPage")
	@ResponseBody
	public Callable<Pagination<DynamicformVo>> getGrid(@ModelAttribute("DynamicformQueryVo") final DynamicformQueryVo queryVo) {
		return new Callable<Pagination<DynamicformVo>>() {
			@Override
			public Pagination<DynamicformVo> call() throws Exception {
				return dynamicformService.queryForPage(queryVo);
			}
		};
	}

 

控制器代码2, 像这样写,正常处理没有报错,可惜不支持异步

/**
	 * 分页查询
	 * 
	 * @param queryVo
	 * @return Pagination<DynamicformVo>
	 */
	@RequestMapping("queryPage")
	@ResponseBody
	public Pagination<DynamicformVo> getGrid(@ModelAttribute("DynamicformQueryVo") final DynamicformQueryVo queryVo) {
		return dynamicformService.queryForPage(queryVo);
	}

报错如下:

 如上所述,Shiro 在处理Servlet3异步请求时会出现异常?要怎么处理呢?可以通过log4j配置把该错误屏蔽掉,但这不是我想要的效果!
