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
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);
}
}
