核心代码实现

实体类设计

// Article.java - 文章实体
package com.example.cms.entity;
import com.baomidou.mybatisplus.annotation.*;
import lombok.Data;
import java.time.LocalDateTime;
import java.util.List;
@Data
@TableName("cms_article")
public class Article {
    @TableId(type = IdType.AUTO)
    private Long id;
    private String title;
    private String summary;
    @TableField("content")
    private String content;
    private Long categoryId;
    private Long authorId;
    private String coverImage;
    @TableField("status")
    private Integer status; // 0-草稿 1-已发布 2-已下线
    @TableField("view_count")
    private Integer viewCount;
    @TableField(fill = FieldFill.INSERT)
    private LocalDateTime createTime;
    @TableField(fill = FieldFill.INSERT_UPDATE)
    private LocalDateTime updateTime;
    @TableLogic
    @TableField("deleted")
    private Integer deleted;
    // 非数据库字段，用于关联查询
    @TableField(exist = false)
    private Category category;
    @TableField(exist = false)
    private List<Tag> tags;
}

// Category.java - 栏目实体
package com.example.cms.entity;
import com.baomidou.mybatisplus.annotation.*;
import lombok.Data;
import java.time.LocalDateTime;
import java.util.List;
@Data
@TableName("cms_category")
public class Category {
    @TableId(type = IdType.AUTO)
    private Long id;
    private String name;
    @TableField("slug")
    private String slug;
    private Long parentId;
    private Integer sort;
    @TableField("status")
    private Integer status;
    private LocalDateTime createTime;
    @TableField(exist = false)
    private List<Category> children;
}

文章服务层

// ArticleService.java
package com.example.cms.service;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.example.cms.dto.ArticleDTO;
import com.example.cms.entity.Article;
import com.example.cms.mapper.ArticleMapper;
import com.example.cms.vo.ArticleVO;
import org.springframework.beans.BeanUtils;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service
public class ArticleService extends ServiceImpl<ArticleMapper, Article> {
    // 分页查询文章列表
    public IPage<ArticleVO> getArticlePage(Integer pageNum, Integer pageSize, Integer status, Long categoryId) {
        Page<Article> page = new Page<>(pageNum, pageSize);
        Page<ArticleVO> result = new Page<>(pageNum, pageSize);
        // 使用自定义SQL查询，关联分类表
        List<ArticleVO> articleVOs = baseMapper.selectArticleListWithCategory(
            page, status, categoryId
        );
        BeanUtils.copyProperties(articleVOs, result.getRecords());
        result.setTotal(page.getTotal());
        result.setPages(page.getPages());
        return result;
    }
    // 发布文章
    @Transactional
    public Long publishArticle(ArticleDTO dto) {
        Article article = new Article();
        BeanUtils.copyProperties(dto, article);
        article.setStatus(1);
        article.setViewCount(0);
        // 保存文章
        save(article);
        // 保存文章标签关联
        if (dto.getTagIds() != null && !dto.getTagIds().isEmpty()) {
            baseMapper.insertArticleTags(article.getId(), dto.getTagIds());
        }
        // 更新文章数量统计
        updateCategoryArticleCount(dto.getCategoryId(), 1);
        return article.getId();
    }
    // 更新文章
    @Transactional
    public boolean updateArticle(Long id, ArticleDTO dto) {
        Article article = getById(id);
        if (article == null) {
            return false;
        }
        // 如果分类改变，更新分类文章数量
        if (!article.getCategoryId().equals(dto.getCategoryId())) {
            updateCategoryArticleCount(article.getCategoryId(), -1);
            updateCategoryArticleCount(dto.getCategoryId(), 1);
        }
        BeanUtils.copyProperties(dto, article);
        return updateById(article);
    }
    // 删除文章（逻辑删除）
    @Transactional
    public boolean deleteArticle(Long id) {
        Article article = getById(id);
        if (article == null) {
            return false;
        }
        // 逻辑删除
        removeById(id);
        // 更新分类文章数量
        updateCategoryArticleCount(article.getCategoryId(), -1);
        return true;
    }
    // 增加浏览次数
    @Cacheable(value = "articleViewCount", key = "#articleId")
    public void incrementViewCount(Long articleId) {
        baseMapper.incrementViewCount(articleId);
    }
    // 获取热门文章
    public List<ArticleVO> getHotArticles(Integer limit) {
        return baseMapper.selectHotArticles(limit);
    }
    private void updateCategoryArticleCount(Long categoryId, int count) {
        baseMapper.updateCategoryArticleCount(categoryId, count);
    }
}

安全的API接口控制

// ArticleController.java
package com.example.cms.controller;
import com.example.cms.common.Result;
import com.example.cms.dto.ArticleDTO;
import com.example.cms.service.ArticleService;
import com.example.cms.vo.ArticleVO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;
@RestController
@RequestMapping("/api/articles")
public class ArticleController {
    @Autowired
    private ArticleService articleService;
    // 文章列表（公开接口）
    @GetMapping
    public Result list(@RequestParam(defaultValue = "1") Integer page,
                      @RequestParam(defaultValue = "10") Integer size,
                      @RequestParam(required = false) Integer status,
                      @RequestParam(required = false) Long categoryId) {
        return Result.success(articleService.getArticlePage(page, size, status, categoryId));
    }
    // 文章详情（公开接口）
    @GetMapping("/{id}")
    public Result detail(@PathVariable Long id) {
        // 增加浏览量
        articleService.incrementViewCount(id);
        return Result.success(articleService.getById(id));
    }
    // 发布文章（需要管理员权限）
    @PostMapping
    @PreAuthorize("hasRole('ADMIN')")
    public Result create(@Valid @RequestBody ArticleDTO dto) {
        Long articleId = articleService.publishArticle(dto);
        return Result.success("文章发布成功", articleId);
    }
    // 编辑文章（需要管理员权限）
    @PutMapping("/{id}")
    @PreAuthorize("hasRole('ADMIN')")
    public Result update(@PathVariable Long id, @Valid @RequestBody ArticleDTO dto) {
        boolean success = articleService.updateArticle(id, dto);
        return success ? Result.success("文章更新成功") : Result.error("文章不存在");
    }
    // 删除文章（需要管理员权限）
    @DeleteMapping("/{id}")
    @PreAuthorize("hasRole('ADMIN')")
    public Result delete(@PathVariable Long id) {
        boolean success = articleService.deleteArticle(id);
        return success ? Result.success("文章删除成功") : Result.error("文章不存在");
    }
    // 获取热门文章（公开接口）
    @GetMapping("/hot")
    public Result hotArticles() {
        return Result.success(articleService.getHotArticles(10));
    }
}

运行与部署

本地运行

# 克隆项目
git clone https://github.com/your-project/cms-system.git
# 进入项目目录
cd cms-system
# 安装依赖
mvn clean install
# 运行项目
mvn spring-boot:run

Docker部署

# Dockerfile
FROM openjdk:8-jre-alpine
ADD target/cms-system.jar app.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "/app.jar"]

# 构建镜像
docker build -t cms-system .
# 运行容器
docker run -d -p 8080:8080 \
  -e DB_HOST=database \
  -e REDIS_HOST=redis \
  --link mysql:database \
  --link redis:redis \
  cms-system

初始化数据

-- 初始化管理员账号
INSERT INTO sys_user (username, password, role) 
VALUES ('admin', '$2a$10$...加密后的密码', 'ADMIN');
-- 初始化示例分类
INSERT INTO cms_category (name, slug, parent_id, sort, status) VALUES 
('技术', 'technology', 0, 1, 1),
('产品', 'product', 0, 2, 1),
('设计', 'design', 0, 3, 1);

这个案例包含了CMS系统的主要功能，您可以根据实际需求进行扩展，比如增加评论系统、用户系统、SEO优化模块等。
