<struts>
<constant name="struts.devMode" value="true" />
<package name="resultTypes" namespace="/r" extends="struts-default">
<action name="r1">
<result type="dispatcher">/r1.jsp</result>
</action>
<action name="r2">
<result type="redirect">/r2.jsp</result>
</action>
<action name="r3">
<result type="chain">r1</result>
</action>
<action name="r4">
<result type="redirectAction">r2</result>
</action>
</package>
</struts> dispatcher - forward运用服务器跳转 服务器跳转 显示actionredirect - 重定向 跳转到jsp
chain 服务器跳转
redirectAction<package name="public" extends="struts-default">
<!-- Chain creatAccount to login, using the default parameter -->
<action name="createAccount" class="...">
<result type="chain">login</result>
</action>
<action name="login" class="...">
<!-- Chain to another namespace -->
<result type="chain">
<param name="actionName">dashboard</param>
<param name="namespace">/secure</param>
</result>
</action>
</package>
<package name="secure" extends="struts-default" namespace="/secure">
<action name="dashboard" class="...">
<result>dashboard.jsp</result>
</action>
</package> 通过例子可以看出，是通过为chain配置actionName参数和namespace参数；//前端htm <body> Result类型 <ol> <li><a href="user/user?type=1">返回success</a></li> <li><a href="user/user?type=2">返回error</a></li> <li><a href="user/user?type=3">返回global result</a></li> <li><a href="admin/admin">admin,继承user包</a></li> </ol> </body>
//struct.xml
<struts>
<constant name="struts.devMode" value="true" />
<package name="user" namespace="/user" extends="struts-default">
<global-results>
<result name="mainpage">/main.jsp</result>
</global-results>
<action name="index">
<result>/index.jsp</result>
</action>
<action name="user" class="com.struts2.user.action.UserAction">

<result name="error">/user_error.jsp</result>
</action>
</package>
<package name="admin" namespace="/admin" extends="user">
<action name="admin" class="com.struts2.user.action.AdminAction">
<result>/admin.jsp</result>
</action>
</package>
</struts>//类包
//AdminAction
package com.struts2.user.action;
import com.opensymphony.xwork2.ActionSupport;
public class AdminAction extends ActionSupport {
@Override
public String execute() throws Exception {
return "mainpage";
}
}
//UserAction
package com.struts2.user.action;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport {
private int type;
public int getType() {
return type;
}
public void setType(int type) {
this.type = type;
}
@Override
public String execute() throws Exception {
if(type == 1) return "success";
else if (type == 2) return "error";
else return "mainpage";
}
}
<package name="user" namespace="/user" extends="struts-default">
<global-results>
<result name="mainpage">/main.jsp</result>
</global-results>
<action name="index">
<result>/index.jsp</result>
</action>
<action name="user" class="com.struts2.user.action.UserAction">
<result>/user_success.jsp</result>
<result name="error">/user_error.jsp</result>
</action>
</package>
这段配置文件中，result 为success时，调用user_success.jsp，result为error时，调用 <package name="admin" namespace="/admin" extends="user">
<action name="admin" class="com.struts2.user.action.AdminAction">
<result>/admin.jsp</result>
</action>
</package>
extends的作用是从另外一个包里面继承配置信息，工作中使用对项目进行分模块处理，每个模块都有公共的配置信息，这样可以将公共配置信息定义为<global-results>，然后被各个模块继承，简化处理。和c++/java中的继承关系好像啊！<package name="struts-default" abstract="true">默认定义了拦截器
<default-interceptor-ref name="defaultStack"/> <default-class-ref class="com.opensymphony.xwork2.ActionSupport" />结论：配置很复杂，使用不需改。
