1. springmvc進行錯誤跳轉配置如下

<!--  shiro為整合springMvc 攔截異常 -->
	<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
		<property name="exceptionMappings">
			<props>
               <!-- 這裡你可以根據需要定義N多個錯誤異常轉發 -->
				<prop key="org.apache.shiro.authz.AuthorizationException">redirect:/shiro/401</prop>
			</props>
		</property>
	</bean>
 

@RequestMapping("/401")
	public String authorizationException(ModelMap modelMap, HttpServletRequest request) {
		String requestType = request.getHeader("X-Requested-With");
		// ajax 請求
		if (requestType != null && requestType.equals("XMLHttpRequest")) {
			return "redirect:/shiro/asyn401";
		} else {
			return "redirect:/shiro/syn401";
		}
	}

	// 非同步
	@RequestMapping("/asyn401")
	public void asyn401(ModelMap modelMap, HttpServletRequest request, HttpServletResponse response) {
		ResultDto resultDto = new ResultDto();
		resultDto.setResult(ResultDto.resultCode_401);
		try {
			super.writeJSON(response, resultDto);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	// 同步
	@RequestMapping("/syn401")
	public String syn401(ModelMap modelMap, HttpServletRequest request) {
		return "/shiro/401";
	}
