Spring GetMapping import오류

Example05Controller.java 예제 하던 중에 GetMapping이 import되지 않는 문제.

package com.springmvc.chap05;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/home")
public class Example05Controller {

	
	@GetMapping("/exam05")
	public String requestMethod(Model model)
	{
		model.addAttribute("data", "Model 예제입니다.");
		model.addAttribute("data2", "웹 요청 URL은 /home/exam05입니다.");
		return "webpage05";
	}
}

pom.xml에서 jason문구를 주석처리해줘야 한다.(포트충돌이 일어나기 때문)

      <!-- JSON 
      <dependency>
         <groupId>com.fasterxml.jackson.core</groupId>
         <artifactId>jackson-databind</artifactId>
         <version>2.16.0</version>
      </dependency>  -->

또한, properties태그를 넣어줘야 한다.

   <properties>
      <java-version>17</java-version>
      <org.springframework-version>5.3.19</org.springframework-version>
      <org.aspectj-version>1.6.10</org.aspectj-version>
      <org.slf4j-version>1.6.6</org.slf4j-version>
  </properties>
