Looks like you have a memory leak in your code, ie you are somewhere keeping references to object you no longer need and thereby prevent them from being garbage collected. 看起来您的代码中存在内存泄漏，即您在某处保留对不再需要的对象的引用，从而防止它们被垃圾回收。

To find out which objects are causing the problem and where references to them are kept, use a heap or memory profiler. 要找出导致问题的对象以及保留对它们的引用的位置，请使用堆或内存分析器。

The VisualVM tool that comes with newer JDK versions includes a heap profiler that is sufficient in most cases. 较新的JDK版本附带的VisualVM工具包括一个在大多数情况下足够的堆分析器。
