How To Calculate Non-Persistent Property via JPA @PostLoad

Description: This application is an example of calculating a non-persistent property of an entity based on the persistent entity attributes. In this case, we will use JPA, @PostLoad.

Key points:

  • annotate the non-persistent field and property with @Transient
  • define a method annotated with @PostLoad that calculates this non-persistent property based on the persistent entity attributes
