测试代码

Cache.set("test-101", "101", 30);
Cache.set("test-201", "201", 60);
Cache.set("test-301", "301", 90);

效果

receive redis published message, channel __keyevent@0__:expired, message xxxx:S:test-101
receive redis published message, channel __keyevent@0__:expired, message xxxx:S:test-201
receive redis published message, channel __keyevent@0__:expired, message xxxx:S:test-301
