Java 服务中的字段存储库需要一个名为'；实体管理工厂&x27；那是找不到的

如何在crud应用程序中解决此问题？ 这是我的错误

***************************
APPLICATION FAILED TO START

Description:

Field repository in com.howtodoinjava.demo.service.UtentiServiceImpl required a bean named 'entityManagerFactory' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

这些是我的课

RepoConfig.java

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    entityManagerFactoryRef = "modelEntityManagerFactory",
    transactionManagerRef = "transactionManager",
    basePackages = { "com.howtodoinjava.demo" }
)
@EnableAutoConfiguration
public class RepoConfig {

    @Primary
    @Bean(name = "modelDataSource")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }


    @Primary
    @Bean(name = "modelEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder 
    builder, @Qualifier("modelDataSource") DataSource dataSource) {
    return builder
                .dataSource(dataSource)
                .packages(UtentiEntity.class)
                .persistenceUnit("unipass")
                .build();
    }

    @Primary
    @Bean(name = "modelSessionFactory")
    public SessionFactory sessionFactory(@Qualifier("modelDataSource") DataSource dataSource) {
        LocalSessionFactoryBuilder localSessionFactoryBuilder = new 
        LocalSessionFactoryBuilder(dataSource);
        return localSessionFactoryBuilder.buildSessionFactory();
    }

    @Primary
    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager(
    @Qualifier("modelEntityManagerFactory") EntityManagerFactory entityManagerFactory) {
        return new JpaTransactionManager(entityManagerFactory);
    }
}

    @Id

    @Column(name="vat")
    private String vat;

}

utientityrepository.java

@Repository
public interface UtentiEntityRepository extends JpaRepository<UtentiEntity, String> {

}

UtentiServiceImpl.java

    @Service
public class UtentiServiceImpl implements UtentiService{
    @Autowired
    private UtentiEntityRepository repository;

    @Override
    public UtentiEntity getUtentiEntityById(String id) throws RecordNotFoundException
    {
        Optional<UtentiEntity> utentiEntity = repository.findById(id);

        if(utentiEntity.isPresent()) {
            return utentiEntity.get();
        } else {
            throw new RecordNotFoundException("No employee record exist for given id");
        }
    } 
}

@服务
公共类UtentiServiceImpl实现UtentiService{
@自动连线
专用存储库；
@凌驾
public UtentiEntity getUtentiEntityById（字符串id）引发RecordNotFoundException
{
可选的utientity=repository.findById（id）；
if（utientity.isPresent（））{
return-utientity.get（）；
}否则{
抛出新的RecordNotFoundException（“给定id不存在员工记录”）；
}
} 
}

UtentiEntityController.java

@RestController
@RequestMapping("/utenti")
public class UtentiEntityController
{
    @Autowired
    UtentiServiceImpl service;

    @GetMapping("/{id}")
    public ResponseEntity<UtentiEntity> getUtentiEntityById(@PathVariable("id") String id)
                                                    throws RecordNotFoundException {
        UtentiEntity entity = service.getUtentiEntityById(id);

        return new ResponseEntity<UtentiEntity>(entity, new HttpHeaders(), HttpStatus.OK);
    }
}

@RestController
@请求映射（“/utenti”）
公共类用户实体控制器
{
@自动连线
UtentiServiceImpl服务；
@GetMapping（“/{id}”）
public ResponseEntity GetUtenetiEntityById（@PathVariable（“id”）字符串id）
抛出RecordNotFoundException{
utientity entity=service.getutientitybyid（id）；
返回新的ResponseEntity（实体，new-HttpHeaders（），HttpStatus.OK）；
}
}

只需在任何配置文件中创建此bean：-）可能与spring hibernate版本兼容…Maria如果这里的配置有点混乱，最简单的方法是在这里生成整个项目
