Spring Data JPA simplifies database interactions in Java applications, by managing the complexity of object-relational mapping (ORM). At the hearth of this feature are annotation mapping Java objects to DB tables. In this reference, I explain how to use annotations such as @Entity, @Table, @Column, @Id, @ManyToOne, and more, using Read more…
Java type erasure You can work with java generics, but still, don’t understand type erasure? Let’s look at this example: The generic T is to perform type check at compile-time. To implement this generic, the compiler will: replace the T parameter with the bound classes or Object insert type casts to Read more…
