List 타입과 Map 타입 프로퍼티 전달 받기

1. List 타입 프로퍼티 전달받기

1) ListCollection 

package com.model.di.exam06;

import java.util.List;

public class ListCollection {

private List<String> userName;

private List<String> getUserName(){

return userName;

}

public void setUserName(List<String> userName) {

this.userName = userName;

}

public void display() {

System.out.println("********** list 목록 ********** ");

for(String name : userName)

System.out.println(name);

}

}

2) 실행 클래스

package com.model.di.exam06;

import org.springframework.context.support.AbstractApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.model.di.exam05.SystemMonitor;

public class Main {

public static void main(String[] args) {

AbstractApplicationContext context = 

new ClassPathXmlApplicationContext("applicationContext.xml");

context.registerShutdownHook();

ListCollection list = (ListCollection)context.getBean("list");

list.display();

context.close();

}

}

3) 설정 파일

<value>홍길동</value>

<value>이순신</value>

<value>강감찬</value>

</list>

</property>

</bean>

</beans>

2. Map 타입 프로퍼티 전달받기

1) MapCollection 

package com.model.di.exam07;

import java.util.Map;

public class MapCollection {

private Map<String, Object> map;

public void setMap(Map<String, Object> map){ 

this.map = map;

}

public void display() {

System.out.println("********* map 목록 *********");

System.out.println(map);

}

}

2) 실행 클래스

package com.model.di.exam07;

import org.springframework.context.support.AbstractApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.model.di.exam06.ListCollection;

public class Main {

public static void main(String[] args) {

AbstractApplicationContext context = 

new ClassPathXmlApplicationContext("applicationContext.xml");

context.registerShutdownHook();

MapCollection map = (MapCollection)context.getBean("map");

map.display();

context.close();

}
