struts2（数据转换校验和国际化）

数据转换
数据校验
国际化

数据转换

jsp页面传送到后台带的数据默认都是字符串，但是如果要把数据封装到对象中，就要转换为对象对应的属性类型

字符转list

user类

package com.model;
public class User {
	//name属性
    private String name;
    //age属性
    private int age;
    //tel属性
    private String tel;
    //各属性的getter和setter()方法
}

action

package com.action;
import java.util.List;
import com.model.User;
import com.opensymphony.xwork2.ActionSupport;
public class ListAction extends ActionSupport{
	private static final long serialVersionUID = 1L;
	//users属性，为List类型
	private List<User> users;
	//getter方法
	public List<User> getUsers() {
		return users; 
	}
	//setter方法
	public void setUsers(List<User> users) {
		this.users = users;
	}
	//重载execute()方法
	public String execute() throws Exception {
		for (User user : users) {
			System.out.println("Name:"+user.getName()+" Age:"+user.getAge()+" Tel:"+user.getTel());
		}
		
		return SUCCESS;
	}
