ERR EXEC without MULTI - spring redis+jedis

[高寒]

I meet with exception during a transactional operation with spring-data-redis

I read this post ERR EXEC without MULTI - Jedis which indicates a multi with exec, I also have redisTemplate.setEnableTransactionSupport(true); enabled, the error stood still.

I removed operation logic within the multi-exec block, I found there is no difference whatever is there, the exception happens event with a zero-operation block.

however, the data is actually stored in redis server side, i can get them in log and redis-cli

RedisTemplate<String,Object> cartCache;

public void create(final Cartline cartline) {
  Object txResults = cartCache.execute(new SessionCallback<List>() {
    public List execute(RedisOperations operations) throws DataAccessException {
      String cartId = cartline.getMemberId();
      String cartlineId = cartline.getCartlineId();
      operations.multi();    
      ......           
      return operations.exec();
    }
  });
}

Can you show an example of the commands you are using between the operations.multi() and operations.exec() call?

Looking at an example of RedisOperations being used: http://goo.gl/AN1x2U , it looks like you are doing more or less the right stuff... though I can't say for certain (I'm not a Java developer, and I've never used Spring or Jedis).

Could you please specify what Redis, Jedis, Spring-Redis version do you use?
