#### 【例】spring注入Map集合 ####

#### 创建User类 ####

package com.shw;
    public class User {
    	private String username;
    	private String password;
    	public String getUsername() {
    		return username;
    	}
    	public void setUsername(String username) {
    		this.username = username;
    	}
    	public String getPassword() {
    		return password;
    	}
    	public void setPassword(String password) {
    		this.password = password;
    	}
    }

#### 创建Manger类 ####

package com.shw;
    import java.util.Map;
    public class Manger {
    	private Map<String,User> userMap;
    	public Map<String, User> getUserMap() {
    		return userMap;
    	}
    	public void setUserMap(Map<String, User> userMap) {
    		this.userMap = userMap;
    	}
    }

#### 配置applicationContext.xml ####

#### 创建测试类 ####

public static void main(String[] args) {
    		//加载applicationContext.xml
    		ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
    		//获取实例
    		Manger manger=(Manger) context.getBean("manger");
    		//调用方法
    		Map<String,User> userMap=manger.getUserMap();
    		Iterator it=userMap.keySet().iterator();
    		while(it.hasNext()){
    			String key=(String)it.next();
    			User user=userMap.get(key);
    			System.out.println(user.getUsername()+","+user.getPassword());
    		}
    	}

##### 运行结果： #####
