SpringBoot整合Redis实现消息发布订阅

前言：

• SpringBoot整合Redis此处不作赘述
• 为减少篇幅，只有部分代码（不影响使用）
• 本文基于lombok插件以及logback日志，所以如果某些注解报错或者无法导入基本是这两处的问题
• 勿喷

正文

• Redis常量配置（个人习惯，本类按需求而定）

  public class RedisConstant {
      /**
     	 * 消息订阅点赞主题
     	 */
     	public static final String TOPIC_PRAISE = "TOPIC_PRAISE";
     	/**
     	 * 消息订阅收藏主题
     	 */
     	public static final String TOPIC_COLLECT = "TOPIC_COLLECT";
     	/**
     	 * 消息订阅评论主题
     	 */
     	public static final String TOPIC_COMMENT = "TOPIC_COMMENT";
     	/**
     	 * 消息订阅关注主题
     	 */
     	public static final String TOPIC_FOCUS = "TOPIC_FOCUS";
  }
