Annotation for a JDBC test that focuses only on JDBC-based components.


Using this annotation will disable full auto-configuration and instead apply only
configuration relevant to JDBC tests.

 By default, tests annotated with @JdbcTest are transactional and roll back at the end of each test. They also use an embedded in-memory database (replacing any explicit or usually auto-configured DataSource). The @AutoConfigureTestDatabase annotation can be used to override these settings. 
 If you are looking to load your full application configuration, but use an embedded database, you should consider @SpringBootTest combined with @AutoConfigureTestDatabase rather than this annotation. 
 When using JUnit 4, this annotation should be used in combination with @RunWith(SpringRunner.class).
