使用自定义基础存储库配置 Spring @DataJpaTest [英] Configure Spring @DataJpaTest with custom base repository

问题描述

让我们假设一个自定义基础 JpaRepository 实现如下.

Let's assume a custom base JpaRepository implementation like the following.

public class SimpleCustomJpaRepository<T, ID extends Serializable> extends SimpleJpaRepository<T, ID> implements CustomJpaRepository<T, ID> {

    @Override
    public List<T> findAllCustom() {

        ...
    }
}

使用 @EnableJpaRepositories 注释注册基础存储库.

The base repository is registered using the @EnableJpaRepositories annotation.

@EnableJpaRepositories(value = "org.somebody.repository", repositoryBaseClass = SimpleCustomJpaRepository.class)

我应该如何为扩展 CustomJpaRepository 接口的 UserRepository 配置集成测试，并为此使用自定义基本实现?

How should I configure a integration test for the UserRepository that's extending the CustomJpaRepository interface and should therefor use the custom base implementation?

public interface UserRepository extends CustomJpaRepository<User, Long> { ... }

当前使用的集成测试失败，出现 org.springframework.data.mapping.PropertyReferenceException: No property findAllCustom found for type User!.实际上，它无法加载 ApplicationContext，因为我的自定义基础存储库实现在集成测试期间未注册，因此未找到 findAllCustom 的实现.

The currently used integration test fails with org.springframework.data.mapping.PropertyReferenceException: No property findAllCustom found for type User!. Actually it failed to load the ApplicationContext because my custom base repository implementation is not registered during integration test and therefor no implementation for findAllCustom was found.

@ExtendWith(SpringExtension.class)
@DataJpaTest
class UserRepositoryTest {

    @Autowired
    private UserRepository userRepository. 
}

我应该如何结合 JPA 存储库集成测试注册自定义 JpaRepository 实现?

How should I register a custom JpaRepository implementation in combination with a JPA repository integration test?

推荐答案

我还是无法解释问题的原因，但是手动配置JPA已经解决了我的问题.

I still can't explain the cause of the problem, but manually configuring the JPA has solved my problem.

@TestConfiguration
@EnableAutoConfiguration(exclude = {JpaRepositoriesAutoConfiguration.class})
@EnableJpaRepositories(value = "org.somebody.repository", repositoryBaseClass = SimpleCustomJpaRepository.class)
public class JpaTestConfig {

    ...
}

我刚刚在我的测试中导入了这个额外的配置类，它就像一个魅力.

I just imported this additional configuration class in my tests and it works like a charm.

@ExtendWith(SpringExtension.class)
@DataJpaTest
@Import(JpaTestConfig.class)
class UserRepositoryTest {

    @Autowired
    private UserRepository userRepository. 
}
