feature exists. Test declares that it has an open, committed, closed feature, but does not have a rollback feature, and the transation in test is the most important to decide whether or not to commit to the database, which plays a role in protecting the data site.2. When integrating spring MVC, classes with @service are not scanned in the MVC configuration file, which causes transactions to become normal beans rather than beans with transaction manag

What is spring data? Spring data is an open source framework for simplifying database access and supporting cloud services. Its primary goal is to make access to data easy and efficient, and to support map-reduce frameworks and cloud computing data Services.

Declare an interface extension library and type it, or one of its child domain classes and ID types, it will handle.Interface Personrepository extends Repository2, the method of new conditional query on the interface.Interface Personrepository extends RepositoryList}3. To create proxy instances for these interfaces, you can pass Javaconfig:Import org.springframework.data.jpa.repo

transaction is integrated with the JTA subsystem of the server. Spring simply passes the obtained entitymanagerfactory, passing it to the Application object through dependency injection, and manages the transaction for it (typically through Jtatransactionmanager).Note that if more than one persistence unit is used in the same application, the bean name of the persisted unit that Jndi obtains should match the name of the persistence unit that the appl

SQL statements?For example: The two classes of our userrepository and Userrepositoryimpl are written as follows.Public interface Userrepository extends JparepositorySo why do you do this here? The reason: SPRING-DATA-JPA provides the underlying crud work, but also provides the functionality of the business logic (which is where the power of the framework is), so

example, some interfaces you only want to provide an increased operation and do not want to provide a method of deletion. In this case, developers can only go back to the Repository interface and then copy the method declaration that they want to keep to the custom interface in Crudrepository.3.
