问题描述

我正在使用 Spring boot 和 jpa 。它是这里

我有一个看起来像这样的域名。此外，似乎实体注释已被弃用，因此我使用的是 DynamicUpdate 。

I've got a domain that looks like this. Also it seems Entity annotation is deprecated so I am using DynamicUpdate instead.

@Data
@AllArgsConstructor
@NoArgsConstructor
@DynamicUpdate
public class Person {
    private String id;
    private String name;
}

我的 SpringBootApplication 类看起来像这样

@SpringBootApplication
@ComponentScan("com.lapots.breed.platform.cloud.boot")
@EnableJpaRepositories("com.lapots.breed.platform.cloud.boot.repository")
@EntityScan("com.lapots.breed.platform.cloud.boot.domain")
public class JavaCloudSampleApplication {

    public static void main(String[] args) {
        SpringApplication.run(JavaCloudSampleApplication.class, args);
    }

    // executed after all beans instantiated
    @Bean
    public CommandLineRunner data(PersonRepository repository) {
        return (args) -> {
            repository.save(new Person(UUID.randomUUID().toString(), "Nike"));
        };
    }
}

repository 类看起来像这样

@Repository
public interface PersonRepository extends JpaRepository<Person, String> {
}

service that使用此类看起来像这样

service that uses this class looks like this

@Service
@Transactional
public class PersonService implements IPersonService {

    @Autowired
    private PersonRepository personRepository;

    @Override
    public Person findPerson(String id) {
        return personRepository.findOne(id);
    }

    @Override
    public Person generatePerson() {
        Person person = new Person();
        person.setId(UUID.randomUUID().toString());
        person.setName("Nike");
        return person;
    }
}

但是当我启动应用程序时出现错误

But when I start application I get the error

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'personService': Unsatisfied dependency expressed through field 'personRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error

有什么问题？

推荐答案

可能人需要实体注释，因为您使用的是JPA。

Maybe Person needs the Entity annotation since you are using JPA.

@Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
@DynamicUpdate
public class Person {
    private String id;
    private String name;
}
