Spring Boot 게시판 만들기 2 - 게시글 작성페이지 만들기

2. 게시글 작성페이지 설계도메인 설계하기사용자로부터 게시글 제목, 작성자 이름, 게시글 내용과 게시글들을 구별해주기 위해 Id값과 게시글이 언제 작성되었는지 알기 위한 작성시간을 추가해 도메인을 만든다. Post.java @Entity@NoArgsConstructor@AllArgsConstructor@Builder@Getterpublic class Post { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @NotEmpty private String title; @NotEmpty private String name; @NotEmpty private String content; @NotNull private LocalDateTime writeTime;} DTO 작성하기사용자로부터 Form을 통해 title, name, content를 입력 받는다. Post 객체를 사용해 데이터를 전달받을 수 있지만 View로직이 추가되게 된다. Entity는 DB와 데이터를 주고 받는 객체이기에 DTO를 만들어 Entity를 View로직으로부터 분리해 추후 생길 수 있는 문제를 없애도록 한다.

Spring Boot 게시판 만들기 1 - 게시글 작성 페이지

1. 게시글 작성 페이지 만들기간단하게 게시글 제목, 사용자 이름, 게시글 내용 세가지만 입력 받는 폼을 만들 것이다. 게시글 작성페이지는 Bootstrap을 이용해 만들건데, BootsWatch의 Cosmo navbar가 마음에 들어 이것도 사용할 것이다. 먼저, Bootstrap 사이트에서 css, js, fonts를 다운 받고 BootsWatch사이트 Cosmo 페이지에서 custom.min.css을 다운 받은 후 springboot 프로젝트내의 resources/static위치에 폴더들은 넣는다. Bootstrap 사이트 : https://getbootstrap.com/docs/4.6/getting-started/introduction/Bootswatch 사이트 : https://bootswatch.com/

JWT를 이용해 AccesToken관리하기JwtUtil 클래스에서는 JWT를 생성하기 위한 createToken메서드가 존재한다. JWT에는 userId와 name을 넣을 것이고 HMAC-SHA256 해싱 알고리즘을 사용해 토큰의 유효성을 검사할 것이다. public class JwtUtil { private String secret; public JwtUtil(String secret) { this.secret = secret; } public String createToken(Long userId, String name) { Key key = Keys.hmacShaKeyFor(secret.getBytes()); String token = Jwts.builder() .claim("userId", 1004L) .claim("name", name) .signWith(key, SignatureAlgorithm.HS256) .compact(); return token; }} JWT가 올바르게 생성됐는지 확인하는 테스트 코드class JwtUtilTest { @Test public void createToken(){ String secret = "12345678901234567890123456789012"; JwtUtil jwtUtil = new JwtUtil(secret); String token = jwtUtil.createToken(1004L, ""); assertThat(token).contains("."); }} JwtUtil을 Bean으로 등록@Configuration@EnableWebSecuritypublic class SecurityConfig extends WebSecurityConfigurerAdapter { // application.yml에 정의된 JWT Secret값을 가져온다. @Value("${jwt.secret}") private String secret; @Override protected void configure(HttpSecurity http) throws Exception { http .cors().disable() .csrf().disable() .formLogin().disable() .headers().frameOptions().disable(); } @Bean public PasswordEncoder passwordEncoder(){ return new BCryptPasswordEncoder(); } @Bean public JwtUtil jwtUtil(){ return new JwtUtil(secret); }} 사용자 요청 결과로 JWT반환하는 로직을 구현/session 경로로 사용자 정보를 받으면 우선 사용자 유효성을 확인한 뒤, 등록된 사용자인 경우 사용자 정보를 JWT에 일부 담아 Response Body에 넣어 사용자에게 반환한다.
