应用Spring mvc HandlerExceptionResolver 处理异常全局跳转方法

应用Spring mvc HandlerExceptionResolver 处理异常全局跳转方法

对于系统异常跳转，可以采用全局跳转的方式，避免在每个controller方法做跳转判断，同时打印异常的的请求uri，可以快速查找问题的入口。

1、配置：applicationContext.xml 加入bean <bean class="com.bbc.common.BBCExceptionResolver" />

2、实现 HandlerExceptionResolver 接口，参考如下例子：

public class BBCExceptionResolverimplements HandlerExceptionResolver {

privatestatic Logger logger = Logger.getLogger(BBCExceptionResolver.class);

/**

* 处理异常跳转

*/

@Override

public ModelAndView resolveException(HttpServletRequest request,

HttpServletResponse response, Object handler, Exception ex) {

if (ex instanceof org.springframework.web.HttpSessionRequiredException) {

StringuserName = CookieUtil.getUserName(request);

returnnew ModelAndView("user/login").addObject("account",userName);

}

String url = request.getRequestURI();

String param =request.getQueryString();

if (param != null &¶m.length() > 0) {

url += ("?" +param);

}

logger.error("异常跳转: "+ url, ex);//把漏网的异常信息记入日志

return new ModelAndView("error");

}

}
