置顶、加精、删除

功能实现

  • 点击“置顶”、“加精”、“删除”，修改帖子的状态
    • 在DiscussPostMapper增加修改方法
    • DiscussPostService、DiscussPostController相应增加方法，注意在Es中同步变化
    • 要在EventConsumer增加消费删帖事件
    • 修改html和js文件

权限管理

  • 版主可以执行“置顶”、“加精”操作。管理员可以执行“删除”操作。
    • 在SecurityConfig类下配置，置顶、加精、删除的访问权限。

按钮显示

  • 版主可以看到“置顶”、“加精”按钮。管理员可以看到“删除“按钮。
    • 导包：thymeleaf-extras-springsecurity5，thymeleaf对security的支持。
