struts中异常的处理

首先建一个异常类：

package blog;

public class MyException extends Exception {

   private static final long serialVersionUID = 421319254124592915L;

   public MyException(String message){
       super(message);
   }

}

再建一个ApplicationResources.properties文件：

invaliduser=it is a invalid user

在struts-config.xml中的actionmapping节点的action节点中加入exception节点：

<exception type="it.cast.MyException" key="invaliduser" path="/Error.jsp"></exception>

在struts-config.xml中加入message-resource节点：

<message-resources parameter="blog.ApplicationResources" key="myKey"></message-resources>

Error.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">

    <title>My JSP 'Login.jsp' starting page</title>
</head>

<body>
    an exception occured!
    <html:errors/>
</body>
</html>
