Struts2的iterator标签遍历Map

Struts2的iterator标签遍历Map

一，struts.xml

<package name="express" extends="struts-default" namespace="/exp">
		<action name="expressMap" class="com.testmap.action.MapAction">
			<result name="result">/jsp/strMap.jsp</result>
		</action>
	</package>

二、JavaBean类

public class Person {

	private String name;
	private String ID;
	private int age;
	private Phone phone;
	
	Person(String name, String ID,int age)
	{
		this.name = name;
		this.ID= ID;
		this.age = age;
	}
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}

	public Phone getPhone() {
		return phone;
	}

	public void setPhone(Phone phone) {
		this.phone = phone;
	}

	public String getID() {
		return ID;
	}

	public void setID(String iD) {
		ID = iD;
	}
	
}

package com.testmap.action;

public class Phone {

	private String name;
	private long xuhao;
	
	Phone(String name, long xuhao)
	{
		this.name = name;
		this.xuhao = xuhao;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public long getXuhao() {
		return xuhao;
	}

	public void setXuhao(long xuhao) {
		this.xuhao = xuhao;
	}
	
}

package com.testmap.action;

import com.opensymphony.xwork2.ActionSupport;

public class MapAction extends ActionSupport{
	 
	 private Map<Person, List<Phone>> ppmap = new HashMap<Person, List<Phone>>();

	 @Override
	 public String execute() throws Exception {

	  List<Phone> phones = new ArrayList<Phone>();
	  phones.add(new Phone("Htc", 12345677L));
	  phones.add(new Phone("apple", 987654321L));
	  Person p = new Person("xiaoming", "bala", 21);
	  ppmap.put(p, phones);
	  
	  return "result";
	 }

	public Map<Person, List<Phone>> getPpmap() {
		return ppmap;
	}

	public void setPpmap(Map<Person, List<Phone>> ppmap) {
		this.ppmap = ppmap;
	}

	
}

三、jsp页面

<div align="center">
			<s:iterator value="ppmap.keySet()" var="key">
				<s:property value="#key.ID" />
				<s:property value="#key.name" />
				<s:property value="#key.age" /><p>
				<s:iterator value="ppmap.get(#key)" var="ph">
					<s:property value="#ph.name" />
					<s:property value="#ph.xuhao" /><p>
				</s:iterator>
				
			</s:iterator>
	</div>
