Question

我想用KeyExpirationEventMessageListener监听过期事件，但我找不到一个例子。

有人知道如何使用Spring boot 1.4.3＆amp; amp; Spring Data Redis？

我目前正在做这个

    JedisPool pool = new JedisPool(new JedisPoolConfig(), "localhost");
    this.jedis = pool.getResource();
    this.jedis.psubscribe(new JedisPubSub() {
        @Override
        public void onPMessage(String pattern, String channel, String message) {
            System.out.println("onPMessage pattern " + pattern + " " + channel + " " + message);
            List<Object> txResults = redisTemplate.execute(new SessionCallback<List<Object>>() {
                public List<Object> execute(RedisOperations operations) throws DataAccessException {
                    operations.multi();
                    operations.opsForValue().get("val:" + message);
                    operations.delete("val:" + message);
                    return operations.exec();
                }
            });
            System.out.println(txResults.get(0));
        }
    }, "__keyevent@0__:expired");

我想直接使用Spring而不是Jedis。

此致

请勿KeyExpirationEventMessageListener使用RedisKeyExpiredEvent，因为它会触发RedisKeyValueAdapter.onApplicationEvent，导致RedisMessageListenerContainer失败。

而是使用@Bean RedisMessageListenerContainer keyExpirationListenerContainer(RedisConnectionFactory connectionFactory) { RedisMessageListenerContainer listenerContainer = new RedisMessageListenerContainer(); listenerContainer.setConnectionFactory(connectionFactory); listenerContainer.addMessageListener((message, pattern) -> { // event handling comes here }, new PatternTopic("__keyevent@*__:expired")); return listenerContainer; }：

RedisMessageListenerContainer

@RunWith(SpringRunner.class) @SpringBootTest @AutoConfigureTestDatabase // Otherwise I have a NullPointer, don't know why @TestPropertySource( properties = {"management.health.mail.enabled=false"}) public class MailServiceTest extends CommonServiceTest {在自己的主题上运行所有通知。
