Jedis does not support returning PendingMessagesSummary

Question

When I start the spring app write with Java 11, show error like this:

[12:36:01:729] [ERROR] - com.dolphin.soa.post.common.mq.PendingMessageConsume.pendingMessage(PendingMessageConsume.java:36) - handle pending message with an error

I have already upgrade the Jedis version to the newest 4.2.3, why still did not support the Redis pending command? I have already read the Jedis issue . They already added the pending support in the Jedis 3.6.0, why still tell me that did not support? This is the project Jedis dependencies look like:

     |    |    |    +--- org.springframework.boot:spring-boot-test-autoconfigure:2.6.7

this is my java code looks like:

void handlePendingMessage(){
        StreamOperations<String, String, String> streamOperations = this.stringRedisTemplate.opsForStream();
       PendingMessagesSummary pendingMessagesSummary = streamOperations.pending(consumer,groupName);
       Long totalPendingMessageCount = pendingMessagesSummary.getTotalPendingMessages();
       String groupName = pendingMessagesSummary.getGroupName();
        List<MapRecord<String, String, String>> retVal = streamOperations.read(Consumer.from(groupName, "my_consumer1"), StreamOffset.create(consumer, ReadOffset.from("0")));
        for (MapRecord<String, String, String> record : retVal ) {
            //streamOperations.acknowledge(groupName, record);
        }
    }

what should I do to make it support PendingMessagesSummary ?

Answer 1

You are not using Jedis directly. You are using it through spring-data-redis.

Even though Jedis has added the support of PendingMessagesSummary, spring-data-redis has not included the support of Jedis. That is why you are getting the error.
