Java – optionally using cascading in Hibernate / JPA

My question is simple, but overall it's very important - I think I did research for hours, but I couldn't find anything useful

Introduction: I have an entity named employee - it is the central class of my system (such as its human resource management) Through the writing center, I think it has a lot to do with other members It contains the onetoone, onetomany and manytoone properties Problem: in some cases, I have to refresh this entity (it also has basic properties, such as' string name; ') – after changing in an entitymanager context (hibernate session), I have to refresh in other instances Of course I can use it:

entityManager.refreash(employee);

But... It will also refresh the entities related to "one hundred" (mentioned: 1-1, - 1,1-relationships), because these relationships have the annotation parameter cascade All or cascade REFREASH. Nothing is needed in that case - I only use the employee entity itself in this case What is unwanted, because it will hit the performance and even take 0.5 seconds locally... Question: is there a way to refresh the entity and optionally "close" the cascade of its attributes Perhaps: is there a way to refresh specific attributes of entities only using hibernate / JPA?

I really don't want hibernate to trigger those 20 longer SQL queries when I refresh my entities in those cases, but it is needed in other cases

In other words, I would say that I need options like "respectcascadesonrefresh = true / false", which can be set before refresh

Any other ideas?

Any help, appreciation,

Pedro

Solution

>First, if you refresh only two or three fields, use the standard API

PS: No, you can't use cascading manually because this annotation is used once when generating the database scheme
