项目添加Struts2容器，使用标签s:iterator来遍历输出。
index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>

Home.java
package top.k10000;
import java.util.ArrayList;
import org.hibernate.Session;
import com.opensymphony.xwork2.ActionSupport;
public class Home extends ActionSupport{
private static final long serialVersionUID = 1L;
private ArrayList<User> list;
public ArrayList<User> getList() {
return list;
}
public void setList(ArrayList<User> list) {
this.list = list;
}
public Home(){
Session session=HibernateSessionFactory.getSession();//通过HibernateSessionFactory类的getSession方法获得Session对象
ArrayList mylist=(ArrayList) session.createQuery("from User s").list();//执行HQL语句，查询内容，并转换为list集合
this.list = mylist;
for(int i=0;i<mylist.size();i++){
User stu=(User)mylist.get(i);//获取到对象的值
System.out.println("Id:"+stu.getId()+",Name:"+stu.getName()+",Sex:"+stu.getSex()+",Age:"+stu.getAge());//打印从stu对象里获取到的值
}
session.close();
}
public String display() {
return SUCCESS;
}
}效果：
