问题描述

我已经在本地部署了一个非常简单的spring boot应用程序.它只有一个类-控制器.就是这样. 我注意到的是堆分配不稳定，并且有峰值和突然下降.为什么会这样呢.我还没有打过该应用程序.

I have deployed a very simple spring boot application locally. It has only one class - controller. That's pretty much it. What I've noticed is that heap allocation is not stable and is having peaks and sudden drops. Why is that happening. I have not done a single call to the app.

推荐答案

使用VisualVM监视应用程序这一事实已经导致Java Heap中的分配.

The fact that you are monitoring the application with VisualVM already leads to allocations in Java Heap.

VisualVM通过JMX与JVM对话；您基本上正在观察这种交流的效果.

VisualVM talks to JVM through JMX; you are basically observing the effect of this communication.
