1 普通结果集

2 全局结果集

<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.bjsxt.struts2.user.action.UserAction">
     <result>/user_success.jsp</result>
     <result name="error">/user_error.jsp</result>
     </action>
    </package>

    <package name="admin" namespace="/admin" extends="user">
    <action name="admin" class="com.bjsxt.struts2.user.action.AdminAction">
      <result>/admin.jsp</result>
    </action>
    </package>
</struts>

动态结果集：

1 HTML

<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>
</ol>

2 JAVA

public class UserAction extends ActionSupport {
private int type;

private String r;

public String getR() {
return r;
}

public void setR(String r) {
this.r = r;
}

public int getType() {
return type;
}

public void setType(int type) {
this.type = type;
}

@Override
public String execute() throws Exception {
  if(type == 1) r="/user_success.jsp";
  else if (type == 2) r="/user_error.jsp";
  return "success";
}

}

3 Struts.xml
<struts>
    <constant name="struts.devMode" value="true" />
    <package name="user" namespace="/user" extends="struts-default">

     <action name="user" class="com.bjsxt.struts2.user.action.UserAction">
     <result>${r}</result>
     </action>
    </package>

</struts>

传递参数

package com.bjsxt.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 {
return "success";
}

}

<struts>
    <constant name="struts.devMode" value="true" />
    <package name="user" namespace="/user" extends="struts-default">

     <action name="user" class="com.bjsxt.struts2.user.action.UserAction">
     <result type="redirect">/user_success.jsp?t=${type}</result>
     </action>
    </package>
