Today i needed to learn the difference between MappedSuperclass and Inheritance especially for use in my personal project.
There was two tables, Person and Role. The Person table it's a super table, so there was more tables that inherits properties and methods from it, does not have the need for a table Person in the database, so Person does not use the Entity annotation.
But, i need to use the OneToMany and ManyToOne annotation between Person and Role tables, but how Person does not use Entity, the OneToMany annotation was not possible in Role (Yes, i also learned this).
I searched in the StackOverflow and haved founded these links:
JPA: Implementing Model Hierarchy - @MappedSuperclass vs. @Inheritance
What do i have learned from that:
MappedSuperclass: Will only be used to inherits props and methods and will not create a table in the database for it.
Inheritance: With the use of the prop (strategy = InheritanceType.TABLE_PER_CLASS) and the Entity annotation, will inherits the props and methods, and also, create a table for it in the database.
if there is some misunderstood in my text, let me know so i can change it.
Thanks for reading and i hope i helped.
