Struts2中集合收集表单数据

收集表单的页面：

<form action="listAction1!insert" method="post">
        dog1:<input name="ulist[0].dog.did"/>
            <input name="ulist[0].dog.dname"/><br>
        dog2:<input name="ulist[1].dog.did"/>
            <input name="ulist[1].dog.dname"/><br>
        dog3:<input name="ulist[2].dog.did"/>
            <input name="ulist[2].dog.dname"/><br>
        dog4:<input name="ulist[3].dog.did"/>
            <input name="ulist[3].dog.dname"/><br>
        dog5:<input name="ulist[4].dog.did"/>
            <input name="ulist[4].dog.dname"/><br>
        dog6:<input name="ulist[5].dog.did"/>
            <input name="ulist[5].dog.dname"/><br>
            <input type="submit" value="提交"/>
    </form>

 struts.xml里：

<action name="listAction1" class="com.xsl.action.ListAction1">
　　<result name="success">/success.jsp</result>
</action>

ListAction1.java里：

package com.xsl.action;

import java.util.ArrayList;
import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.interceptor.ServletRequestAware;

import com.opensymphony.xwork2.ActionSupport;
import com.xsl.entity.Dog;
import com.xsl.entity.Users;

public class ListAction1 extends ActionSupport implements ServletRequestAware {
    private Users users;
    private HttpServletRequest request;
    private List<Users> ulist;
    public String insert(){
        for(Users u:ulist){
            System.out.println(u.getDog().getDid()+"---"+u.getDog().getDname());
        }
        return SUCCESS;
    }
    public void setServletRequest(HttpServletRequest request) {
        this.request = request;
    }
    public Users getUsers() {
        return users;
    }
    public void setUsers(Users users) {
        this.users = users;
    }
    public HttpServletRequest getRequest() {
        return request;
    }
    public void setRequest(HttpServletRequest request) {
        this.request = request;
    }
    public List<Users> getUlist() {
        return ulist;
    }
    public void setUlist(List<Users> ulist) {
        this.ulist = ulist;
    }
}
