redis - 没有 MULTI 的 ERR EXEC - spring redis + jedis

Question

我在使用 spring-data-redis 进行事务操作时遇到异常

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();
    }
  });
}

我读了这篇文章 ERR EXEC without MULTI - Jedis这表示带有 exec 的 multi，我也启用了 redisTemplate.setEnableTransactionSupport(true);，但错误仍然存​​在。

我删除了 multi-exec block 中的操作逻辑，我发现那里没有任何区别，异常发生事件与零操作 block 。

我遇到了同样的问题，并通过将 spring-data-redis 从 1.4.2.RELEASE 更新到 1.5.2.RELEASE 来修复它。
