How does AccessingDataJpaApplication work?
First, it fetches the CustomerRepository from the Spring application context. Then it saves a handful of Customer objects, demonstrating the save () method and setting up some data to work with. Next, it calls findAll () to fetch all Customer objects from the database. Then it calls findById () to fetch a single Customer by its ID. Finally, it calls findByLastName () to find all customers whose last name is "Bauer". The demo () method returns a CommandLineRunner bean that automatically runs the code when the application launches.
How many constructors are there in JPA?
You also have two constructors. The default constructor exists only for the sake of JPA. You do not use it directly, so it is designated as protected. The other constructor is the one you use to create instances of Customer to be saved to the database.

What is a customer repository?

How to specify access type?
We can explicitly specify the access type by using AccessType.PROPERTY or AccessType.FIELD of the @Access annotation. We can use @Access on the class level or field or method level. We can even mix the two types in a single entity class. The other persistence annotations e.g. @Id, @GeneratedValue, @Column etc should be used consistently on the specified access type, otherwise behavior will be unspecified; we will probably have exceptions in that case.
What happens if you put persistence annotations on fields?
If we place persistence annotations (@Id, @Column etc) on the fields rather than on getters/setters, then JPA provider will access the entity via fields.
Can AccessType.Property override class level access type?
Following example shows the usage of AccessType.Proper ty on class level and AccessType.Field on one of the fields. That way, we can override the specified class level access type on the fields/properties selectively.
