Why Spring Boot 2.0 application does not run schema.sql?

Question

While I was using Spring Boot 1.5, on application startup Hibernate executed schema.sql file located in /resources folder when appropriate configuration is

Answer 1

Not embedded (e.g. MySQL)

If you load a database that is not embedded, in Spring Boot 2 you need to add:

spring.datasource.initialization-mode=always

Check the Migration Guide:

Database Initialization

Basic DataSource initialization is now only enabled for embedded data sources and will switch off as soon as you’re using a production database. The new spring.datasource.initialization-mode (replacing spring.datasource.initialize) offers more control.

Embedded (e.g. h2)

I once had a similar problem, even though it was an h2 (so it was an embedded DB), my h2 configuration was activated by a my-test profile.

My test class was like:

@RunWith(SpringRunner.class)
@SpringBootTest                     // does not work alone
@ActiveProfiles("my-test")
public class MyEntityRepositoryTest {

The problem is @SpringBootTest alone did not initialize the test database. I had to either use @DataJpaTest or @SpringBootTest+@AutoConfigureTestDatabase. Examples

@RunWith(SpringRunner.class)
@DataJpaTest                       // works
@ActiveProfiles("sep-test")
public class MyEntityRepositoryTest {

or

@RunWith(SpringRunner.class)
@SpringBootTest                     // these two
@AutoConfigureTestDatabase          // together work
@ActiveProfiles("sep-test")
public class MyEntityRepositoryTest {
