@Configuration
public class AppConfig {
	@Bean
	public Messaging messaging1() {
		return new ActiveMQMessaging();
	}
	
	@Bean
	public Messaging messaging2() {
		return new MMSMessaging();

app (실행)

public class AppMain05 {
	public static void main(String[] args) {
		AbstractApplicationContext context = new AnnotationConfigApplicationContext(AppConfig2.class);

		Communication2 communication1 = context.getBean("communication1" , Communication2.class);
		communication1.communicate();
		
		Communication2 communication2 = context.getBean("communication2" , Communication2.class);
		communication2.communicate();
		
		Communication2 communication3 = context.getBean("communication3" , Communication2.class);
		communication3.communicate();
		
		context.close();
	}
}

실행 결과

MD5 알고리즘으로 암호화 합니다.

MD5 알고리즘으로 암호화 합니다.

RSA 알고리즘으로 암호화 합니다.
