spring 3配置文件中如何注入map list set等类型

首先写个 javabean类吧，如下

package com.bean;import java.util.List;import java.util.Map;import java.util.Properties;import java.util.Set;public class MessageBean {private String username;private String password;private int size;private List<String> citys;private Set<String> friends;private Map<Integer,String> books;private Properties props;public void setProps(Properties props) {this.props = props;}public void setFriends(Set<String> friends) {this.friends = friends;}public void setSize(int size) {this.size = size;}public void setPassword(String password) {this.password = password;}public void setUsername(String username) {this.username = username;}public void show(){System.out.println(username);System.out.println(password);System.out.println(size);System.out.println("----------");for(String str:citys){System.out.println(str);}System.out.println("----------");for(String str:friends){System.out.println(str);}System.out.println("---------");Set<Integer> keys = books.keySet();for(Integer key:keys){System.out.println(key+" "+books.get(key));}System.out.println("---------");Set params = props.keySet();for(Object obj:params ){System.out.println(obj+" : "+props.getProperty(obj.toString()));}}public void setCitys(List<String> citys) {this.citys = citys;}public void setBooks(Map<Integer, String> books) {this.books = books;}}

配置文件中配置

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"><beans><bean id="userdao" class="com.dao.impl.HibernateUserDAO"></bean><!-- setter方式注入 --><bean id="useraction" class="com.action.UserAction"> <property name="userDao" ref="userdao"> </property></bean><!-- 构造器方式注入 --><bean id="useraction1" class="com.action.UserAction1"> <constructor-arg index="0" ref="userdao"/></bean><!-- 各种类型值注入的写法 --><bean id="messagebean" class="com.bean.MessageBean"><property name="props"><props><prop key="url">http://www.tom.com</prop><prop key="username">zhangsan</prop><prop key="password">123456789</prop></props></property><property name="books"><map><entry key="10" value="CoreJava"></entry><entry key="11" value="JavaWeb"></entry><entry key="12" value="SSH2"></entry></map></property><property name="friends"><set><value>张三</value><value>李四</value><value>王五</value></set></property><property name="citys"><list><value>北京</value><value>上海</value><value>深圳</value></list></property><property name="username"><value>root</value></property><property name="password"><value>1234</value></property><property name="size"><value>15</value></property></bean></beans>

代码中调用

String[] configs = {"applicationContext.xml"};ApplicationContext ac =new ClassPathXmlApplicationContext(configs);MessageBean msgBean = (MessageBean)ac.getBean("messagebean");msgBean.show();
