JAP will use the default value for example, use the column name in the data table to exactly match the attribute name , so in many cases, you do not need to specify the metadata explicitly. It should be noted that in the Entree class, I did not add annotation to the String property "name" or the boolean property "vegetarian". Of course, the most important thing in the ORM mechanism is to specify the correspondence between Objects and databases.

Because the instances of other classes are also managed by EntityManager, you can specify "cascade" rules. For example, when a Restaurant is deleted, all associated Addresses will also be deleted at the same time. Below, you will see test cases for this scenario. This metadata is used to describe how the primary key is generated in the database.

The best way for Data Access Layer is to establish a common interface to hide all the implementation details of the persistence layer. Switching to other implementations will not affect the system architecture. At the same time, this also provides convenience for the business logic layer, making it easier to implement stub or mock testing. RestaurantDao is an interface. Note that it does not depend on any JPA or Spring classes.

In fact, it only depends on its own domain model in this simple example, there is only one, that is Restaurant :. For the implementation of the interface, I used Spring's JpaDaoSupport class, which provides a convenient method to obtain JpaTemplate.

JpaTemplate is also optional. If you don't want Spring's automatic processing of JPA exception transactions, you can completely avoid using JpaTemplate.
