@DataJpaTest 如何指定要扫描的存储库和实体 [英] @DataJpaTest how to specify repositories and entities to scan

问题描述

默认@DataJpaTest 扫描所有jpa 存储库和@Entity.就我而言，我有 5 个存储库包和 5 个实体包.例如

By default @DataJpaTest scans all jpa repositories and @Entity. In my case I have 5 repositories package and 5 entities package. E.g

com.acme.product.entity 与com.acme.product.repositorycom.acme.users.entity 与com.acme.users.repositorycom.acme.client.entity 与com.acme.client.repository

等等......

我想在单独的课程中测试每个部分.例如

I would like to test each part in a separate classe. E.g.

@RunWith(SpringRunner.class)
@DataJpaTest
//Some configurations to import only product repositories and product entities
public class TestProductRepository {
  @Autowired
  TestEntityManager entityManager;
}

请注意，我已经配置了 5 个不同的 EntityManager 我想导入它们并使用例如 TestProductRepository 中的 productEntityManager 而不是默认 TestEntityManager 加载所有存储库/实体.

Note that I have configured 5 different EntityManager I would like to import them and use for example the productEntityManager in the TestProductRepository instead of the default TestEntityManager which loads all repositories/entites.

非常感谢

推荐答案

这就是我设法实现我想要的:

This is how I manage to achieve what I wanted:

@ActiveProfiles( "dev" )
@RunWith( SpringRunner.class )
@DataJpaTest
// Exclude the default test database + the default EntityManager in purpose to use my configurations instead.
@AutoConfigureTestDatabase( connection = H2, replace = AutoConfigureTestDatabase.Replace.AUTO_CONFIGURED )
@Import( {
    ProductDataBaseConfig.class,//Import ProductEntityManager and other beans related to DB operations like TransactionManager, etc...
    ProductRepositoryContainer.class //Custom bean containing all product repositories
} )
public class TestProductRepository {
  @Autowired
  private TestEntityManager entityManager; 

}

这里重要的是 @AutoConfigureTestDatabase(...) 和 @Import(...)，因为我替换了自动配置的 bean 并导入了我自己的 ProductEntityManager TestEntityManager 使用提供的配置.这也减少了 @DataJpaTest 的范围，它不会扫描类路径中的所有实体和存储库，这正是我想要的.

The important thing here is the @AutoConfigureTestDatabase(...) and @Import(...), as I replaced the autoconfigured beans and import my own ProductEntityManager the TestEntityManager uses that provided configuration. This also reduce the scope of @DataJpaTest which does not scan all entities and repositories in the classpath and that was what I wanted.
