java – Spring @Autowired无法连接Jpa存储库

我在这里明显遗漏了什么.
我正在制作一个简单的弹簧启动应用程序,其中包含弹簧数据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.

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

spring-boot-starter-parentspring-boot-starter-webspring-boot-starter-data-jpa

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(这个不能自动装配)：

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？

最佳答案

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);

    }
}
