      • 搜索并收藏某个课程,添加、删除和搜索自己收藏的课程;
      • 发布、删除和修改自己发布的帖子,搜索所有帖子;

    • 管理员:

      • 包含普通用户所拥有的功能;
  • 待完善的功能:

    • 管理员:
      • 删除课程信息;
      • 增加用户表字段,对用户进行管理,冻结和解除用户账号;
    • 普通用户:
      • 对发布的内容进行敏感词过滤;
      • 删除自己发表的评论或回复;
  • 遇到的问题及解决方案:

    • 由于评论,点赞,帖子查询结果实体互相嵌套,导致fastJson将结果实体转成Json时使用了循环引用,为了不影响转换效率,使用局部关闭循环引用的方式,即在字段上添加注解:@JSONField(serialzeFeatures = {SerializerFeature.DisableCircularReferenceDetect})
  • 打包时记得将OnlinelearningApplicationTests.java文件中的内容注释掉。
