带参数的结果集:
配置文件: <result type="redirect">/user_success.jsp?t=${type}</result>
jsp调用 :
from valuestack: <s:property value="t"/><br/> //取不到,因为客户端跳转后 以前action的值都没有了.
from actioncontext: <s:property value="#parameters.t"/>
1. jsp显示文件:]
<ol> <li><a href="user/user?type=1">传参数</a></li> </ol>
2. struts.xml配置文件:
<?xml version="1.0" encoding="UTF-8" ?>

</action>
</package>
</struts>
3. action文件:
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) {

}
@Override
public String execute() throws Exception {
return "success";
}
