Spring Boot JPA 无法添加自定义存储库答案

【问题标题】：Spring Boot JPA unable to add custom repositorySpring Boot JPA 无法添加自定义存储库
【发布时间】：2017-12-03 12:10:33
【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实现这种行为。

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。

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？

更新

pom.xml 附加。 application.properties 没有变化。

【问题讨论】：

你的代码工作正常，你能显示你的依赖和配置吗？
@ledniov：感谢您的回复。使用 pom.xml 更新问题
现在，将@NoRepositoryBean 添加到TestRepositoryImpl。

标签： spring-boot spring-data-jpa

【解决方案1】：

看来最新里程碑的 spring boot 和 spring 数据有问题，如果你切换回2.0.0.M1 一切正常：

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

最好将问题报告给 Spring Data 团队。
