springboot-data-redis 遇到ERR EXEC without MULTI

說明：

使用springboot的redistemplate接口執行事務

        redisTemplate.multi();
        //此處為業務邏輯
        redisTemplate.exec();

 

時，遇到錯誤：ERR EXEC without MULTI.

 

解決：

查閱官方文檔發現，redistemplate不支持這樣的寫法。需要改成：

//execute a transaction
List<Object> txResults = redisTemplate.execute(new SessionCallback<List<Object>>() {
  public List<Object> execute(RedisOperations operations) throws DataAccessException {
    operations.multi();
    operations.opsForSet().add("key", "value1");

    // This will contain the results of all operations in the transaction
    return operations.exec();
  }
});
System.out.println("Number of items added to set: " + txResults.get(0));

 

問題解決。
