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

	</bean>
	
</beans>

代码中调用

 

 

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