關鍵時刻還是得找Google：https://github.com/devpg/spring-data-redis-example/blob/master/src/test/java/com/devpg/redis/TransactionTest.java

主要是這一句

/*         * By default each template method call creates a new connection - so         * WATCH, MUTLI, EXEC, UNWATCH won‘t work because of the missing         * context. To make use of transaction support use SessionCallback which         * reuses the underlying connection.         */
