Spring Boot JPA无法添加自定义存储库

Question

我尝试在Spring Boot环境中创建自定义存储库。因此，所有的存储库都可以通过扩展它来具有这种行为。

TestRepository.java

@NoRepositoryBean
public interface TestRepository<T> extends JpaRepository<T, Long> {
    Object getMemberValue(Long id, String memberName);
}

TestRepositoryImpl.java

public class TestRepositoryImpl<T> extends SimpleJpaRepository<T, Long> implements TestRepository<T> {
    public TestRepositoryImpl(JpaEntityInformation<T, ?> entityInformation, EntityManager entityManager) {
        super(entityInformation, entityManager);
    }

    @Override
    public Object getMemberValue(Long id, String memberName) {
        //logic to get member value
        return null;
    }
}

样本仓库

@Repository
public interface UserRepository extends TestRepository<User> {
    List<User> findByNameOrderById(String name);
}

启动配置

@SpringBootApplication
@EnableJpaRepositories(repositoryBaseClass = TestRepositoryImpl.class)
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

但是应用程序启动失败，抛出以下异常。

我需要添加自定义仓库的配置吗？

附带pom.xml文件。application.properties文件无更改。

你的代码可以正常工作，能否展示一下你所依赖的库和配置？ - ledniov

@ledniov：感谢回复。问题已更新，附带pom.xml文件。 - Maheshkumar

现在，将@NoRepositoryBean添加到TestRepositoryImpl中。 - mp911de

看起来最新版本的Spring Boot和Spring Data存在问题，如果您切换回2.0.0.M1，一切都可以正常工作：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.M1</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

建议将问题报告给Spring Data团队。
