Spring Boot main 소스

Spring Boot main 소스 하위 패키지만 자동으로 로딩(Controller, Service)

package com.bluexmas;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
//@ComponentScan(basePackages = {"com.bluexmas.controller"})
public class BluexmasApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(BluexmasApplication.class, args);
    }
    
}

Controller 소스

package com.bluexmas.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class SampleController {
	
	@ResponseBody
	@RequestMapping("/sample")
	public String sample() {
		String data = "@ResponseBody 어노테이션을 통해 반환";
		return data;
	}

}
