struts2中的动态结果集

struts2中的动态结果集，举例说明：

1、 url中调用Action

    http://localhost:8080/struts2_1700_DynamicResult/user?type=1

http://localhost:8080/struts2_1700_DynamicResult/user?type=2

 

2、 struts.xml配置文件：

<struts>

    <!-- Add packages here -->

    <constant name="struts.devMode" value="true" />

    <package name="resultType" namespace="/" extends="struts-default">

       <action name="user" class="net.dreamcreating.UserAction">

           <result>${r}</result>

       </action>

    </package>

</struts>

 

3、 在UserAction中包括两个属性：type和r (程序如下所示)

package net.dreamcreating;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {

 

    private static final long serialVersionUID = 1L;

 

    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 = "/user_success.jsp";

       else

           r = "/user_error.jsp";

       return SUCCESS;

    }

}
