  项目结构

• src/main/java/com/blog   - controller   - service   - repository   - model - src/main/resources   - application.properties - pom.xml

  主要功能

1. 用户注册和登录 2. 文章的增删改查CRUD 3. 评论系统 4. 标签系统 5. 分页和搜索 6. 富文本编辑器支持

   项目初始化

   1. pom.xml 配置

   xml dependencies     dependency         groupIdorg.springframework.boot/groupId         artifactIdspring-boot-starter-web/artifactId     /dependency     dependency         groupIdorg.springframework.boot/groupId         artifactIdspring-boot-starter-data-jpa/artifactId     /dependency     dependency         groupIdmysql/groupId         artifactIdmysql-connector-java/artifactId     /dependency     dependency         groupIdorg.springframework.boot/groupId         artifactIdspring-boot-starter-security/artifactId     /dependency     dependency         groupIdorg.springframework.boot/groupId         artifactIdspring-boot-starter-thymeleaf/artifactId     /dependency     dependency         groupIdorg.springframework.boot/groupId         artifactIdspring-boot-starter-validation/artifactId     /dependency /dependencies

   2. application.properties 配置

   properties spring.datasource.urljdbc:mysql://localhost:3306/blog spring.datasource.usernameroot spring.datasource.passwordroot spring.jpa.hibernate.ddl-autoupdate spring.jpa.show-sqltrue spring.jpa.properties.hibernate.dialectorg.hibernate.dialect.MySQL5Dialect

   3. 数据库模型

   3.1 用户模型

   java Entity public class User {     Id     GeneratedValue(strategy GenerationType.IDENTITY)     private Long id; private String username;     private String password;     private String email; // Getters and Setters }

   3.2 文章模型

   java Entity public class Post {     Id     GeneratedValue(strategy GenerationType.IDENTITY)     private Long id; private String title;     private String content;     private LocalDateTime createdAt; ManyToOne     JoinColumn(name user_id)     private User user; ManyToMany     JoinTable(       name post_tag,        joinColumns JoinColumn(name post_id),        inverseJoinColumns JoinColumn(name tag_id))     private SetTag tags new HashSet(); // Getters and Setters }

   3.3 评论模型

   java Entity public class Comment {     Id     GeneratedValue(strategy GenerationType.IDENTITY)     private Long id; private String content;     private LocalDateTime createdAt; ManyToOne     JoinColumn(name post_id)     private Post post; ManyToOne     JoinColumn(name user_id)     private User user; ManyToOne     JoinColumn(name parent_comment_id)     private Comment parentComment; OneToMany(mappedBy parentComment, cascade CascadeType.ALL)     private ListComment replies new ArrayList(); // Getters and Setters }

   3.4 标签模型

   java Entity public class Tag {     Id     GeneratedValue(strategy GenerationType.IDENTITY)     private Long id; private String name; ManyToMany(mappedBy tags)     private SetPost posts new HashSet(); // Getters and Setters }

   4. 数据库仓库

   4.1 用户仓库

   java public interface UserRepository extends JpaRepositoryUser, Long {     OptionalUser findByUsername(String username); }

   4.2 文章仓库

   java public interface PostRepository extends JpaRepositoryPost, Long {     PagePost findAll(Pageable pageable); }

   4.3 评论仓库

   java public interface CommentRepository extends JpaRepositoryComment, Long {     ListComment findByPostId(Long postId);     ListComment findByParentCommentId(Long parentCommentId); }

   4.4 标签仓库

   java public interface TagRepository extends JpaRepositoryTag, Long { }

   5. 服务层

   5.1 用户服务

   java Service public class UserService { Autowired     private UserRepository userRepository; Autowired     private PasswordEncoder passwordEncoder; public User save(User user) {         user.setPassword(passwordEncoder.encode(user.getPassword()));         return userRepository.save(user);     } public OptionalUser findByUsername(String username) {         return userRepository.findByUsername(username);     } }

   5.2 文章服务

   java Service public class PostService { Autowired     private PostRepository postRepository; public Post save(Post post) {         post.setCreatedAt(LocalDateTime.now());         return postRepository.save(post);     } public PagePost findAll(Pageable pageable) {         return postRepository.findAll(pageable);     } }

   5.3 评论服务

   java Service public class CommentService { Autowired     private CommentRepository commentRepository; public Comment save(Comment comment) {         comment.setCreatedAt(LocalDateTime.now());         return commentRepository.save(comment);     } public ListComment findByPostId(Long postId) {         return commentRepository.findByPostId(postId);     } public ListComment findByParentCommentId(Long parentCommentId) {         return commentRepository.findByParentCommentId(parentCommentId);     } }

   6. 控制器

   6.1 用户控制器

   java Controller RequestMapping(/users) public class UserController { Autowired     private UserService userService; PostMapping(/register)     public String register(ModelAttribute User user) {         userService.save(user);         return redirect:/login;     } }

   6.2 文章控制器

   java Controller RequestMapping(/posts) public class PostController { Autowired     private PostService postService; GetMapping     public String list(Model model, Pageable pageable) {         PagePost posts postService.findAll(pageable);         model.addAttribute(posts, posts);         return posts/list;     } PostMapping     public String save(ModelAttribute Post post) {         postService.save(post);         return redirect:/posts;     } }

   6.3 评论控制器

   java Controller RequestMapping(/comments) public class CommentController { Autowired     private CommentService commentService; PostMapping     public String save(ModelAttribute Comment comment) {         commentService.save(comment);         return redirect:/posts/ comment.getPost().getId();     } }

   7. 前端模板使用Thymeleaf

   7.1 登录页面

   html !DOCTYPE html html xmlns:thhttp://www.thymeleaf.org head     titleLogin/title /head body     form th:action{/login} methodpost         div             label forusernameUsername:/label             input typetext idusername nameusername /         /div         div             label forpasswordPassword:/label             input typepassword idpassword namepassword /         /div         div             button typesubmitLogin/button         /div     /form /body /html #### 7.2 文章列表页面 html !DOCTYPE html html xmlns:thhttp://www.thymeleaf.org head     titlePosts/title /head body     div         a th:href{/posts/new}New Post/a     /div     div         ul             li th:eachpost : \({posts}                 h2 th:text\){post.title}/h2                 p th:text\({post.content}/p                 pBy: span th:text\){post.user.username}/span/p                 a th:href{/posts/{id}(id\({post.id})}Read more/a             /li         /ul     /div /body /html #### 7.3 文章详情页面 html !DOCTYPE html html xmlns:thhttp://www.thymeleaf.org head     titlePost Details/title /head body     h1 th:text\){post.title}/h1     p th:text\({post.content}/p     h2Comments/h2     div th:eachcomment : \){comments}         p th:text\({comment.content}/p         pBy: span th:text\){comment.user.username}/span/p         div th:eachreply : \({comment.replies}             p th:text\){reply.content}/p             pBy: span th:text\({reply.user.username}/span/p         /div         form th:action{/comments} methodpost             input typehidden th:value\){comment.id} nameparentComment.id /             textarea namecontent/textarea             button typesubmitReply/button         /form     /div /body /html ### 8. 富文本编辑器支持 在Thymeleaf模板中添加TinyMCE的支持 html !DOCTYPE html html xmlns:thhttp://www.thymeleaf.org head     titleNew Post/title     script srchttps://cdn.tiny.cloud/1/no-api-key/tinymce/5/tinymce.min.js/script     script         tinymce.init({             selector: #content         });     /script /head body     form th:action{/posts} methodpost         div             label fortitleTitle:/label             input typetext idtitle nametitle /         /div         div             label forcontentContent:/label             textarea idcontent namecontent/textarea         /div         div             button typesubmitSave/button         /div     /form /body /html
   通过上述步骤我们已经建立了一个功能完善的个人博客系统。这个系统包括用户注册和登录、文章的增删改查、评论和标签系统以及富文本编辑器的支持。
