在struts2中提供了一些常用的拦截器，其中就包括对异常处理的拦截器，我们直接声明使用即可，下面来看个例子。 struts.xml <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <!-- 对默认拦截器的引入 --> <include file="struts-default.xml" /> <package name="eticket" extends="struts-default"> <!-- 全局异常映射 --> <global-exception-mappings> <exception-mapping result="error" exception="java.lang.Exception"> </exception-mapping> </global-exception-mappings> <action name="airTicketAction" class="AirTicketAction"> <result>airticket/airticket.jsp</result> <result name="detail">airticket/airticketdetail.jsp</result> <result name="order">airticket/airticketorder.jsp</result> <result name="error">error.jsp</result> <!-- 局部异常映射 --> <exception-mapping result="nullPoint" exception="java.lang.NullPointerException"></exception-mapping> <result name="nullPoint">error.jsp</result> </action> </package> </struts> 下面是一个action，产生一个异常，用于测试 AirTicketAction.java import com.opensymphony.xwork2.ActionSupport; @SuppressWarnings("serial") public class AirTicketAction extends ActionSupport { @Override public String execute() throws Exception { // TODO 自动生成方法存根 //产生一个除数为0的异常 int i = 1/0; return SUCCESS; } } 用于显示的jsp页面 error.jsp <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title><s:text name="login.title"></s:text></title> </head> <body> <h1>出错了！</h1> <s:property value="exception.message" /> <s:property value="exceptionStack" /> </body> </html> 很简单，配置完成可以使用了。 文章出处：http://www.diybl.com/course/3_program/java/javajs/2008827/137748_2.html
