2.配置监听beng
@Configuration
public class RedisListenerConfig {
@Bean
RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory) {
RedisMessageListenerContainer container = new RedisMessageListenerContainer();
container.setConnectionFactory(connectionFactory);
return container;
}
}
3.配置监听key
@Component
public class RedisKeyExpirationListener extends KeyExpirationEventMessageListener {
public RedisKeyExpirationListener(RedisMessageListenerContainer listenerContainer) {
super(listenerContainer);
}
@Override
public void onMessage(Message message, byte[] pattern) {
// 获取失效的key
String expiredKey = message.toString();
// 指定key 的前缀=xxxxxx，处理对应业务逻辑，
if (expiredKey.indexOf("saToken") != -1) {
String[] orderOn = expiredKey.split(":");
System.out.println("token"超时" );
}
System.out.println(expiredKey);
}
}
