Java 资源泄漏：'；rset&x27；此位置未关闭

所以我正在做一个项目，我不确定如何处理这个错误，或者可以做些什么来修复它。我已经尝试了我能想到的一切，也许其他人对如何修复它有一些意见。它是用java编写的，用于游戏。错误是资源泄漏：“rset”未在此位置关闭。这是它挑出来的这一行

rset = statement.executeQuery("SELECT * FROM `items` WHERE `owner_id` = " + objectId + " AND `location` = " + ItemLocation.EQUIPMENT.ordinal());

希望有人对如何修复此错误有一些意见，如果我取消警告，它会导致内存泄漏或影响程序的性能吗

检查完“未找到播放机”后，应关闭

rset

之后您正在执行一个新查询，但没有关闭以前的resultset->resource leak。

非常感谢您，这让我抓狂！
