여러 가지 Annotation

Spring Boot Annotations

🌟기본적으로 response는 Object Mapper를 통해서 json 형태로 변경되어 내려지게 됨

⭐ @Configuration 상기하기!

@Configuration
class AppConfig{

    @Bean("base64Encode")
    public Encoder encoder(Base64Encoder base64Encoder){
        return new Encoder(base64Encoder);
    }

    @Bean("urlEncode")
    public Encoder encoder(UrlEncoder urlEncoder){
        return new Encoder(urlEncoder);
    }
}

🌟@Qualifier 상기하기

package com.ioc_di.ioc_di.encoder;

import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Component;

@Component
public class Encoder {
    private IEncoder iEncoder;

    public Encoder(@Qualifier("urlEncoder") IEncoder iEncoder){
        this.iEncoder=iEncoder;
    }

    public void setEncoder(IEncoder iEncoder){
        this.iEncoder=iEncoder;
    }

    public String encode(String msg){
        return iEncoder.encode(msg);
    }

}
