As of version 1.1, an important change has been made to the exec methods of RedisConnection and RedisTemplate. Previously, these methods returned the results of transactions directly from the connectors. This means that the data types often differed from those returned from the methods of RedisConnection. For example, zAdd returns a boolean indicating whether the element has been added to the sorted set. Most connectors return this value as a long, and Spring Data Redis performs the conversion. Another common difference is that most connectors return a status reply (usually the string, OK) for operations such as set. These replies are typically discarded by Spring Data Redis. Prior to 1.1, these conversions were not performed on the results of exec. Also, results were not deserialized in RedisTemplate, so they often included raw byte arrays. If this change breaks your application, set convertPipelineAndTxResults to false on your RedisConnectionFactory to disable this behavior.
