我正在使用Spring boot和jpa。正是在这里
Spring boot
jpa
我有一个看起来像这样的域名。而且似乎Entity不赞成使用注释,所以我DynamicUpdate改用了。
Entity
DynamicUpdate
@Data @AllArgsConstructor @NoArgsConstructor @DynamicUpdate public class Person { private String id; private String name; }
我的SpringBootApplication课看起来像这样
SpringBootApplication
@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
@Repository public interface PersonRepository extends JpaRepository<Person, String> { }
service 使用此类的表看起来像这样
service
@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

问题是什么?
由于您正在使用JPA,因此可能Person需要Entity注释。
Person
@Entity @Data @AllArgsConstructor @NoArgsConstructor @DynamicUpdate public class Person { private String id; private String name; }
