spring 用JavaBean 配备List

spring 用JavaBean 配置List

用数值配置spring装配的JavaBean内部的List类型很容易，下面介绍如何用javabean装配JavaBean中的List

public class Element implements Serializable{/** * */private static final long serialVersionUID = -6956332143541075576L;private Integer id;private String name;private String url;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}}

private List<Element> elementList;public List<Element> getElementList() {return elementList;}public void setElementList(List<Element> elementList) {this.elementList = elementList;}/** * @param args */public static void main(String[] args) {String[] configLocations = {"E:\\test.xml"};ApplicationContext applicationContext = new FileSystemXmlApplicationContext(configLocations);Test test = (Test)applicationContext.getBean("test");List<Element> elList = test.getElementList();for(Element el : elList){System.out.println(el.getId() + " , " + el.getName() + " , " + el.getUrl());}}}

?<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd                      http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd                      http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"><bean id="element0" value="1001"/><property name="name" value="hello"/><property name="url" value="http://www.baidu.com/"/></bean><bean id="element1" value="1002"/><property name="name" value="world"/><property name="url" value="http://www.google.com/"/></bean><bean id="test" /><ref bean="element1" /></list></property></bean></beans>

?这样，两个bean element0和element1就被装配到了bean test里面。
