I am using Lettuce library (5.1.6.Release) as Java redis client to create connection with Redis.
Below is snippet of code from my SpringBoot application using Java 8.
ClientOptions options =
ClientOptions.builder()
.disconnectedBehavior(ClientOptions.DisconnectedBehavior.REJECT_COMMANDS)
.autoReconnect(true)
.build();
LettucePoolingClientConfiguration pool = LettucePoolingClientConfiguration.builder()
.poolConfig(new GenericObjectPoolConfig())
.clientOptions(options)
.clientResources(DefaultClientResources.create())
.useSsl()
.build();
RedisConnectionFactory factory = new LettuceConnectionFactory(new RedisStandaloneConfiguration("host name string here"), pool);
RedisTemplate<String, String> redisConn = new RedisTemplate<>();
redisConn.setConnectionFactory(factory);
redisConn.setKeySerializer(StringRedisSerializer.UTF_8);
redisConn.setValueSerializer(StringRedisSerializer.UTF_8);
redisConn.setEnableTransactionSupport(true);
redisConn is singlton Spring Bean used across services to add data in Redis
SetOperations<String, String> setOperations = redisTemplate.opsForSet();
setOperations.add("key1", "value1");
setOperations.add("key2", "value2");
setOperations.add("key3", "value3");
I am getting below error while doing add operation in redis in a java Single thread provided by Executer service
