Spring Boot内存使用情况（JpaMetamodelMappingContext）

Question

We have Spring Boot Data-Rest project with more than 1000 JPA entities in it. Application starts with initial 4GB memory usage. When I analyze the memory usage via JProfiler, I can see BasicPersistentEntity classes and their propertyCache cover most of the consumption.

Is this the default behaviour, or are we missing something?

Answer 1

I'm not sure how, but it's fixed in Spring Boot 2.1.0.M3 version.

Here is the related commit.
