ERR EXEC without MULTI - spring redis+jedis

问题

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

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();
    }
  });
}

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.

回答1:

I had this same problem and fixed it by updating spring-data-redis from 1.4.2.RELEASE to 1.5.2.RELEASE.
