我一直在我的电脑上本地测试我的网络应用程序，并用VisualVM监控它。我最近也开始使用JMeter，因为有人建议我应该做一些负载测试，因为我怀疑我在某个地方有缓慢的内存泄漏。
今天，我的网络应用程序终于抛出了OutOfMemory异常。我设置了HeapDumpOnOutOfMemoryError和HeapDumpPath参数，以防发生这种情况。生成了堆转储文件。
我在VisualVM中打开了这个文件（java_pid2760.hprof），老实说，我不明白我应该如何找出这次内存泄漏的罪魁祸首。。。
如何使用VisualVM来分析堆转储并找到产生内存泄漏的类/实例？
以下是我发现在调试内存泄漏时很有用的几个链接：

使用VisualVM来分析堆转储和定点内存泄漏并不容易，如果这是您第一次处理此类问题，我不建议您使用此工具。考虑下载HPjmeter并让它为您完成工作。
打开转储文件后，选择“排序的引用图子树”选项。这将显示Web应用程序中按大小排序的所有对象。在大多数内存泄漏场景中，您正在泄漏一种类型的Object，它会随着时间的推移在堆中膨胀。HPjmeter将帮助您快速识别此案例。
