Find spring-data-mongo MappingContext memory leak

Question

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

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

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?

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

看起来你遇到了DATACMNS-855 ，它已在最新的Hopper SR2中修复。
