还是上一个例子，为Bean添加一个属性——地址，他是一个List；
package com.xh.struts2.bean;
import java.util.List;
public class User {
private String userName;
private String password;
private int age;
private List<String> addrs;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public List<String> getAddrs() {
return addrs;
}
public void setAddrs(List<String> addrs) {
this.addrs = addrs;
}
}
在注册页面要求输入多个地址：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>注册</title>
</head>
<body>
<form action="rigest" method="post">
<s:textfield name="user.userName" label="name"></s:textfield>
<s:textfield name="user.password" label="password"></s:textfield>
<s:textfield name="user.age" label="age"></s:textfield>
<s:textfield name="user.addrs" label="addrs"></s:textfield>
<s:textfield name="user.addrs" label="addrs"></s:textfield>
<s:textfield name="user.addrs" label="addrs"></s:textfield>
<button type="submit">注 册</button>
</form>
</body>
</html>
并且在成功页面打印出来：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>欢迎</title>
</head>
<body>
<h2>欢迎</h2>
<h3><s:property value="user.userName"/></h3>
