查找 spring-data-mongo MappingContext 内存泄漏 [英] Find spring-data-mongo MappingContext memory leak

问题描述

我正在调试使用 spring-data-mongodb.1.9.1.RELEASE 的应用程序中的内存泄漏.

I'm debugging a memory leak in my application which uses spring-data-mongodb.1.9.1.RELEASE.

MongoMappingContext 使用了大约 三分之一的堆.它引用了近 3 万个 PersistentEntity 对象，总大小超过 140MB.

MongoMappingContext is using up about a third of the heap. It has a reference to almost 30k PersistentEntity objects totaling over 140MB.

这种内存泄漏是由于持有对 MongoDB 数据对象的不必要的 引用而导致的，因此它们不能被垃圾收集.如果我从不在代码中引用这些 PersistentEntity 对象，为什么会在 MappingContext 中保存这么多对象?

This memory leak is caused by holding unnecessary references to MongoDB data objects so they can't be garbage collected. Why might so many of these objects be held in the MappingContext if I never reference these PersistentEntity objects in my code?

保留我的数据模型对象是否会导致 Spring Data MongoDB 保留它的数据模型对象?

Does holding on to my data model objects cause Spring Data MongoDB to hold onto it's data model objects?
