Controller

package Pack01;

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

@Controller
public class AController {
	@RequestMapping("/")
	public String index() {		
		return "index";
	}
	@RequestMapping("/Tiger")
	public String tiger() {		
		return "Tiger";
	}
}

 

 

application.properties

server.port=9090

spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp

port충돌을 막기위해 port번호를 바꿔준다.

여기서 jsp 파일을 생성할때 경로를 꼭 확인하여 views폴더 안에 jsp파일을 생성하자

 

 

404 error가 뜬다면

import org.springframework.context.annotation.ComponentScan;

application에 추가해준다
