#19.스프링에서 XML 설정 파일의 분리
스프링에서 XML 설정 파일의 분리

XML 설정파일을 여러 개로 분리할 수 있으며 이 경우 ref bean 태그를 사용하여 자바 빈을 로딩 하면 된다.  ApplicationContext를 생성할 때 여러 XML 파일명을 문자열 배열로 넣어주면 된다.

[Dog.java]
package ojc.spring.twoxml;
public interface Dog {
public void jitda();
}

[Jindo.java]
package ojc.spring.twoxml;
import org.springframework.stereotype.Component;
public class Jindo implements Dog{
public void jitda() {
System.out.println("진도진도~");
}
}

[Pudle.java]
package ojc.spring.twoxml;
import org.springframework.stereotype.Component;
public class Pudle implements Dog {
public void jitda() {
System.out.println("푸들푸들~");
}
}

[DogManager.java]
package ojc.spring.twoxml;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

public class DogManager {
           private Pudle pudle;
private Jindo jindo;
public void setPudle(Pudle pudle) {
           this.pudle = pudle;
}

public void setJindo(Jindo jindo) {
           this.jindo = jindo;
}

public void walwal() {
           this.jindo.jitda();
           this.pudle.jitda();
}
}

[DogApp.java]
package ojc.spring.twoxml;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class DogApp {
public static void main(String[] args) {
      ApplicationContext context =
new ClassPathXmlApplicationContext(new String[] {"applicationContext.xml", "dog.xml"});
          
DogManager dManager = (DogManager) context.getBean("dogManager");
dManager.walwal();
}
}
