LZ一開始配置到啟動類裏面，結果出現了主線程阻塞的情況。

如下是流程：

首先修改配置文件redis.conf中的：notify-keyspace-events Ex，默認為notify-keyspace-events "" （註釋掉默認的，註意notify-keyspace-events Ex之前不能有空格）

啟動初始化類裏面的contextInitialized方法中加入以下代碼：（啟動一個線程執行訂閱功能）

Thread thread = new Thread(傳入需要參數--既然是redis監控必然需要jedis參數);
thread.start();

之後再編寫業務代碼

resource.psubscribe(pubSub, "__keyevent@0__:expired");

這裏是訂閱監聽，__keyevent@0__:expired是監聽的頻道

redis監聽類

public class Listener extends JedisPubSub{
    private static Logger logger = Logger.getLogger(Listener.class);

    private XXX xxx;
    private YYY yyy;

    public Listener(XXX xxx, YYY yyy) {
        this.xxx= xxx;
        this.yyy= yyy;
    }

    @Override
 
    public void onPMessage(String pattern, String channel, String message) {
        logger.info("onPMessage: channel[" + channel + "], message[" + message + "]");
        {業務內容}
    }

    @Override
    public void onMessage(String channel, String message) {
        logger.info("onMessage: channel[" + channel + "], message[" + message + "]");
 
    }

    @Override
    public void onSubscribe(String channel, int subscribedChannels) {
        logger.info("onSubscribe: channel[" + channel + "]," + "subscribedChannels[" + subscribedChannels + "]");
    }

    @Override
    public void onUnsubscribe(String channel, int subscribedChannels) {
        logger.info("onUnsubscribe: channel[" + channel + "], " + "subscribedChannels[" + subscribedChannels + "]");
    }

    @Override
    public void onPUnsubscribe(String pattern, int subscribedChannels) {
        logger.info("onPUnsubscribe: pattern[" + pattern + "]," + "subscribedChannels[" + subscribedChannels + "]");
    }

    @Override
    public void onPSubscribe(String pattern, int subscribedChannels) {
        logger.info("onPSubscribe: pattern[" + pattern + "], " + "subscribedChannels[" + subscribedChannels + "]");
    }
}
