Auto-configured Data JDBC Tests
@DataJdbcTest is similar to @JdbcTest but is for tests that use Spring Data JDBC repositories.
By default, it configures an in-memory embedded database, a JdbcTemplate, and Spring Data JDBC repositories.
Only AbstractJdbcConfiguration subclasses are scanned when the @DataJdbcTest annotation is used, regular @Component and @ConfigurationProperties beans are not scanned.
@EnableConfigurationProperties can be used to include @ConfigurationProperties beans.
A list of the auto-configurations that are enabled by @DataJdbcTest can be found in the appendix.

By default, Data JDBC tests are transactional and roll back at the end of each test. See the relevant section in the Spring Framework Reference Documentation for more details. If that is not what you want, you can disable transaction management for a test or for the whole test class as shown in the JDBC example.
If you prefer your test to run against a real database, you can use the @AutoConfigureTestDatabase annotation in the same way as for DataJpaTest.
