logic:redirect 跳转问题
在自己的网站开发中遇到的一个小问题
目的：运行 index.jsp 页 自动跳转到 home.jsp 主页面。
index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<%@ taglib uri="/tld/struts-logic" prefix="logic" %>
<logic:redirect forward="home"/>
struts-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">
<struts-config>
<!-- form -->
<form-beans>
<form-bean name="loginForm" type="com.zero.front.login.action.LoginForm"></form-bean>
</form-beans>
<global-forwards>
<forward name="home" path="/home.do"/>
</global-forwards>
<!-- action -->
<action-mappings>
<action path="/home" validate="false" name="loginForm" forward="/jsp/login/login.jsp" scope="request">
</action>
<action path="/login" type="com.zero.front.login.action.LoginAction" name="loginForm" scope="request">
<forward name="success" path="/jsp/common/home.jsp"></forward>
</action>
</action-mappings>
</struts-config>
以上是源文件
注意的是
1、<logic:redirect forward="home"/> 中 forward 用的是全局变量<global-forwards>
2、<action path="/home" validate="false" name="loginForm" forward="/jsp/login/login.jsp" scope="request"> 直接跳转不需要type的action的写法
3、期间遇到过 “Cannot find ActionMappings or ActionFormBeans collection” 错误是由于struts-config.xml没有配置正确，以及 struts.jar包没有引全 共10个包，还有就是可能 web.xml 配置错误。
