SLF4J：類型的對象上失敗的toString（）調用[com.datastax.driver.core.Responses $結果$行數]

Question

使用

• 卡桑德拉芯：2.1.0
• SLF4J：slf4j- API-1.7.6.jar
• SLF4J-log4j的：SLF4J-log4j12-1.7.2.jar

我得到這個消息在tomcat印刷catalina.out的相當頻繁，而不在丟失任何功能應用：

任何具有cassandra或slf4j知識的人都可以幫助弄清楚是什麼導致這些消息被打印？我在我的開發環境中看不到這些消息。在生產環境中，它會導致我的catalina.out被填滿和維護費用。

嘗試刪除項目中的target文件夾並重建它。一些類可能被緩存。
