Spring Boot JPA 无法添加自定义存储库 [英] Spring Boot JPA unable to add custom repository
本文介绍了Spring Boot JPA 无法添加自定义存储库的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试在 Spring 引导环境中创建自定义存储库.所以我所有的存储库都可以通过扩展它来拥有这种行为.
I tried creating custom repository in Spring boot environment. So all my repositories can have this behavior by extending it.
TestRepository.java
TestRepository.java
@NoRepositoryBean
public interface TestRepository<T> extends JpaRepository<T, Long> {
Object getMemberValue(Long id, String memberName);
}
TestRepositoryImpl.java
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;
}
}
示例存储库
@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);
}
}
但应用程序无法启动并引发以下异常.
But application failed to start and throws below exception.

Description:
Parameter 0 of constructor in com.test.repository.TestRepositoryImpl required a bean of type 'org.springframework.data.jpa.repository.support.JpaEntityInformation' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.data.jpa.repository.support.JpaEntityInformation' in your configuration.我是否缺少添加自定义存储库的任何配置?
Am I missing any configuration to add custom repository?

推荐答案
看起来 spring boot 和 spring data 的最新里程碑有问题，如果你切换回 2.0.0.M1一切正常:
Looks like there's an issue with the latest milestone of spring boot and spring data, if you switch back to 2.0.0.M1 everything works ok:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.M1</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
可能最好将问题报告给 spring 数据团队.
Probably it's better to report the issue to spring data team.
