Spring @Autowired无法连接Jpa存储库

我明显遗漏了一些东西。 我正在制作一个简单的spring boot应用程序，其中包含spring data jpa并面临以下错误：

 Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [locassa.domain.repository.PersonRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:1373) ~[spring-beans-4.2.3.RELEASE.jar:4.2.3.RELEASE] at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1119) ~[spring-beans-4.2.3.RELEASE.jar:4.2.3.RELEASE] at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1014) ~[spring-beans-4.2.3.RELEASE.jar:4.2.3.RELEASE] at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:545) ~[spring-beans-4.2.3.RELEASE.jar:4.2.3.RELEASE] ... 32 common frames omitted 

我的代码：

应用：

 @SpringBootApplication @ComponentScan(basePackages = {"app.controller", "app.domain"}) public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } 

的pom.xml

   4.0.0 pl.mosek pl.mosek 0.1-SNAPSHOT  org.springframework.boot spring-boot-starter-parent 1.3.0.RELEASE    org.springframework.boot spring-boot-starter-web   org.projectlombok lombok 1.16.6   com.h2database h2   org.springframework.boot spring-boot-starter-data-jpa    1.8     org.springframework.boot spring-boot-maven-plugin     

控制器：

 @RestController public class TestController { @Autowired PersonService personService; @RequestMapping("/") public String index() { return "Test spring boot"; } @RequestMapping("/person/{id}") public Person personById(@PathVariable Long id) { return personService.findPerson(id); } } 

PersonService：

 public interface PersonService { Person findPerson(Long id); } 

PersonServiceImpl：

 @Service public class PersonServiceImpl implements PersonService { @Autowired PersonRepository personRepository; public Person findPerson(Long id) { return personRepository.findOne(id); } } 

PersonRepository（这个不能自动assembly）：

 public interface PersonRepository extends CrudRepository { } 

已在网上搜索过。 我没找到一件事。 有任何想法吗？

我也遇到了同样的问题。我用以下解决方案解决了这个问题。 如果您的实体类和存储库位于不同的包中，则需要使用以下注释。

 @SpringBootApplication @EntityScan(basePackages = {"EntityPackage"} ) @EnableJpaRepositories(basePackages = {"RepositoryPackage"}) public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
