<package name="resultType" namespace="/r" extends="struts-default">
<action name="r1">
<!-- result 不指定type默认为dispatcher 运用服务器跳转 forword到jsp压面 显示action地址 -->
<result type="dispatcher">/r1.jsp</result>
</action>
<action name="r2">
<!-- 客户端跳转 显示jsp地址 -->
<result type="redirect">/r2.jsp</result>
</action>
<!-- 同r1 forword到另外一个action -->
<action name="r3">
<result type="chain">r1</result>
</action>
<!-- 同r2 -->
<action name="r4">
<result type="redirectAction">r2</result>
</action>
</package>
<package name="user2" namespace="/user2" extends="struts-default">
<!-- 其他包可以用extends继承 -->
<global-results>
<result name="mainpage">/main.jsp</result>
</global-results>
<action name="user2" class="com.ouc.wkp.action.UserAction2">
<result name="success">/r1.jsp</result>
<result name="error">/r2.jsp</result>
</action>
</package>
<package name="user3" namespace="/user3" extends="struts-default">
<action name="user3" class="com.ouc.wkp.action.UserAction3">

struts.xml
package com.ouc.wkp.action;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction2 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";
}
}
}
UserAction2
动态结果集，在action中保存一个属性，存储具体的结果location
package com.ouc.wkp.action;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction3 extends ActionSupport {
private int type;
private String r;
public int getType() {
return type;
}
public void setType(int type) {
this.type = type;
}
public String getR() {
return r;
}
public void setR(String r) {
this.r = r;
}
@Override
public String execute() throws Exception {
if (type == 1) {
r = "/r1.jsp";
} else if (type == 2) {
r = "/r2.jsp";
} else {
r = "/main.jsp";
}
return SUCCESS;
}
}
UserAction3
使用redirect跳转时是两次request，需要传参
<!-- <result type="redirect">/xxx.jsp?t=${type}</result> -->
前台通过<s:property value="#parameters.t"/>从actioncontext里面取
