A JavaBean is a POJO that is serializable, has a no-argument constructor, and allows access to properties using getter and setter methods that follow a simple naming convention. Because of this convention, simple declarative references can be made to the properties of arbitrary JavaBeans.
The Spring Data JPA is an implementation of the repository abstraction that is a key building block of domain-driven design based on the Java application framework Spring. It transparently supports all available JPA implementations and supports CRUD operations as well as the convenient execution of database queries.
Often a setter is accompanied by a getter, which returns the value of the private member variable. They are also known collectively as accessors . The mutator method is most often used in object-oriented programming , in keeping with the principle of encapsulation .
Setter injection, where the client exposes a setter method which accepts the dependency.
