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

代码中调用

 

 

	String[] configs = {"applicationContext.xml"};

		ApplicationContext ac =

			new ClassPathXmlApplicationContext(configs);

		MessageBean msgBean = 

			(MessageBean)ac.getBean("messagebean");

		msgBean.show();
