Welcome to Gradle 8.3!

Here are the highlights of this release:
 - Faster Java compilation
 - Reduced memory usage
 - Support for running on Java 20

For more details see https://docs.gradle.org/8.3/release-notes.html


Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.3/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

서버에서 Spring 실행시키는 방법 

## 프로젝트 파일로 들어가기 
$ cd hello-spring

$ ll

## gradlew 파일 빌드 
$ ./gradlew build 
$ cd build
$ ll
$ cd libs 
$ ls -arlth

## jar 파일 빌드 
$ java -jar hello-spring-0.0.1-SNAPSHOT.jar

 

 clean을 할 경우 build폴더가 사라짐 

$ ./gradlew clean

스프링 웹 개발 기초 

• 정적 컨텐츠 : 서버에서 파일을 그대로 웹브라우저에 내려주는 것
• MVC와 템플릿 엔진 : 과거 JSP, PHP - html 을 서버에서 변형을 주어 동적으로 바꿔서 내려주는 것 
• API : JSON이라는 데이터 구조 포맷으로 클라이언트에게 데이터를 전달하는 방식  

1. 정적 컨텐츠 : http://localhost:8080/hello-static.html

controller에서 해당 이름을 먼저 찾는다. 컨트롤러가 우선 순위를 가짐! 

그리고 없으면  resources:static/hello-static.html 찾음! 

 

 

2. MVC와 템플릿엔진 

    @GetMapping("hello-mvc")
    public String helloMvc (@RequestParam("name") String name, Model model){
        model.addAttribute("name", name);
        return "hello-template";

http://localhost:8080/hello-mvc?name=spring!

get방식으로 파라미터를 받아야 오류없이 페이지를 띄울 수 있음. 

값을 넘겨주기 위해서는 

GetMapping 주소 다음에 ?name 으로 파라미터를 적어줘야 한다. 

model에 값을 넣어 뷰에게 전달 

이렇게 넘겨진 String name 은 View파일에서 model에 들어있는 ${name}이라는 키 값으로 spring! 이라는 값을 꺼내 hello! empty!! 라는 글에 출력이 된다. 

<html lang="en" xmlns:th="http://www.thymeleaf.org">
<body>
<p th:text="'hello ' + ${name} ">hello! empty!!</p>
</body>
</html>

템플릿 엔진에서는 변환 후 넘겨준다! 

변환된 것을 어떻게 확인하는가? 

소스코드 보기를 하면 바뀌어있는 것을 확인할 수 있다. 

---

3. API 

@ResponseBody 

Body부분에 데이터를 직접 넣어주겠다. 

템플릿 엔진과 차이점! 

뷰가 없고 데이터가 그대로 넘어감. 

커맨드 + shift + enter -> 자동완성
