초기 필요한 폴더 세팅

global.properties

이미지나, 페이지네이션 같은 건 나중에 되면 찾기 힘들다.
global.properties에서 만들고 끌어다 쓴다

board.page.count=10
default.image=classpath:/static/images/default.png

controller

package com.example.controller;

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

@Controller
public class HomeController {

    @GetMapping(value = { "/", "/home", "/main" })
    public String getHome() {
        return "home";
        // /를 붙여도 되고 안붙여도 됨 근데 안붙이는 게 좋은듯
    }

}

config

package com.example.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.
EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.
WebSecurityConfigurerAdapter;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        // 로그인 화면 뜨는 거 막기
        // super.configure(http);

        // h2-console 보안 제거하기 배포 시 주석잡기
        http.csrf().ignoringAntMatchers("/h2-console/**");
        http.headers().frameOptions().sameOrigin();
    }

}

1. 오버라이딩을 한다
2. super.configure(http)는 부모의 기능을 쓰겠다고 선언하는 거임. 이것을 주석처리 한다.
