先上代码：
struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<!-- 请求参数的编码方式 -->
<constant name="struts.i18n.encoding" value="UTF-8" />
<!-- 当struts.xml改动后，是否重新加载。默认值为false(生产环境下使用),开发阶段最好打开 -->
<constant name="struts.configuration.xml.reload" value="true" />
<!-- 设置浏览器是否缓存静态内容。默认值为true(生产环境下使用),开发阶段最好关闭 -->
<constant name="struts.serve.static.browserCache" value="false" />
<!-- 将struts2委托Spring管理 -->
<constant name="struts.objectFactory" value="spring" />
<!-- 是否开启动态方法调用 -->
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<!-- 是否使用struts的开发模式。开发模式会有更多的调试信息。默认值为false(生产环境下使用),开发阶段最好打开 -->
<constant name="struts.devMode" value="true" />
<!-- 设置默认的父包，一般我们都设置一个default包继承自struts-default。大部分类再继承default。如果有特殊的类需要特殊的包，只能在action中再指定父包了。 -->
<constant name="struts.convention.default.parent.package"
value="default" />
<!-- 默认配置包路径包含action,actions,struts,struts2的所有包都会被struts作为含有Action类的路径来搜索。通过设置struts.convention.package.locators属性来修改这个配置。 -->
<constant name="struts.convention.package.locators" value="action,actions,controller,web" />
<!-- 约定Action类名：要求Action的命名必须以Action为后缀，可以使用下面常量来修改后缀限制 -->
<constant name="struts.convention.action.suffix" value="Action" />
<package name="default" extends="struts-default">
<global-results>
<!-- <result name="error1">/commons/error1.jsp</result> -->
<result name="error2">/commons/error2.jsp</result>
<result name="login">/login/login.jsp</result>
</global-results>
<global-exception-mappings>
<!-- <exception-mapping result="error1" exception="java.lang.Exception"/> -->
**<exception-mapping result="error2" exception="com.lz.shop.web.action.MyException" />**
<exception-mapping result="sqlException" exception="java.sql.SQLException" />
</global-exception-mappings>
</package>
</struts>
这一句为什么会无效呀？试了很多办法都不行
求大神解答！
自定义异常类：
MyException.java
package com.lz.shop.web.action;
public class MyException extends Exception {
/**
*
*/
private static final long serialVersionUID = -4567535714727601736L;
public MyException() {
super();
}
private String message="bmddddd";
public MyException(String message) {
this.message = message;
}
public String getMessage() {
return message;
}
}
error2.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>ERROR1</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

</head>
<body>
<span>ERROR2</span>
<s:fielderror></s:fielderror>
<s:property value="exception.message" />
</body>
</html>
Action测试类:
LoginAction.java
package com.lz.shop.web.action;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import com.lz.shop.entity.base.User;
import com.lz.shop.web.BaseSupport;
@Scope
@Controller
@Namespace("/user")
@ParentPackage("default")
public class LoginAction extends BaseSupport {
/**
*
*/
private static final long serialVersionUID = 6336185736252504861L;
private User user;
/**
* 验证登陆
*
* @return
*/
@Action(value = "loginAction", results = {
@Result(name = "success", location = "/index.jsp", type = "redirect"),
@Result(name = "input", location = "/login/login.jsp") })
public String login() {
//抛个空指针异常来测试
if (user.getUsername() == "1"
&& user.getPassword() == "1") {
System.out.println("success");
return "success";
} else {
System.out.println("input");
return "input";
}
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
struts2版本是2.2.1
求大神支招！！！
这一句怎么弄也没有效果，求大神解答！
<exception-mapping result="error2" exception="com.lz.shop.web.action.MyException" />
这一句！
