🎋 Mustache

머스테치(Mustache)를 이용해 화면을 만들어보자.

플러그인 설치 후

➡️

dependencies {
	...
    implementation('org.springframework.boot:spring-boot-starter-mustache')
	...
}

build.gradle > dependencies에 위와 같이 추가

➡️

오른쪽 상단에 뜨는 🐘🔄를 눌러주자.

🎋 Index 화면 만들고 실행해보기

src/main/java/com.test.spring.boot_crud/web/IndexController.java

  package com.test.spring.boot_crud.web;

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

  @Controller
  public class IndexController {

      @GetMapping("/")
      public String index(){
          return "index";
      }
  }

ㅋ 아 그럼 그렇지, 내가 한번에 될 리가 없다 ㅎ

🤷‍♀️ File > Settings > Build, … > Build Tools > Gradle projects > Build and run using / Run tests using

Gradle로 되어있던 것을 IntelliJ IDEA로 바꾸기.

다시 실행해보자. 😳

~~ㅅㅂ ㅠ~~

MySQL에서 create database ㄱㄱ -> application.propertie 파일을 열고

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:포트번호/DB명?useSSL=false&useUnicode=true&serverTimezone=Asia/Seoul
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.format_sql=true

위 내용 복붙하기. (포트번호, DB명, username, password 바꿀 것)

다시 다시 실행해보자.
