无法自动装入字段：JpaRepository，Spring

Question

我正尝试在服务中自动装入资源库。但它抛出一个BeanCreationException。嵌套的例外是

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Cannot create inner bean '(inner bean)#208fa9ab' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#208fa9ab': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' is defined 

这是我的Hibernate配置文件

@Configuration 
@EnableTransactionManagement 
@EnableJpaRepositories(basePackages ="nfy.sltraveller.repository") 
@ComponentScan({ "nfy.sltraveller.configuration" }) 
@PropertySource(value = { "classpath:application.properties" }) 
public class HibernateConfig { 

@Autowired 
private Environment environment; 

@Bean 
public LocalSessionFactoryBean sessionFactory() { 
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 
    sessionFactory.setDataSource(dataSource()); 
    sessionFactory.setPackagesToScan(new String[] { "nfy.sltraveller.model"  }); 
    sessionFactory.setHibernateProperties(hibernateProperties()); 
    return sessionFactory; 
} 

@Bean 
public DataSource dataSource() { 
    DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName")); 
    dataSource.setUrl(environment.getRequiredProperty("jdbc.url")); 
    dataSource.setUsername(environment.getRequiredProperty("jdbc.username")); 
    dataSource.setPassword(environment.getRequiredProperty("jdbc.password")); 
    return dataSource; 
} 

private Properties hibernateProperties() { 
    Properties properties = new Properties(); 
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect")); 
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql")); 
    properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql")); 
    return properties;   
} 

@Bean 
@Autowired 
public HibernateTransactionManager transactionManager(SessionFactory s) { 
    HibernateTransactionManager txManager = new HibernateTransactionManager(); 
    txManager.setSessionFactory(s); 
    return txManager; 
} 
} 

这里是服务，

@Service 
public class InitDbService { 

@Autowired 
private UserRepository userRepository; 

@Autowired 
private RoleRepository roleRepository; 

@PostConstruct 
public void init(){ 
    Role roleUser = new Role(); 
    roleUser.setName("ROLE_USER"); 
    roleRepository.save(roleUser); 
} 
} 

这里是仓库，

package nfy.sltraveller.repository; 

import org.springframework.data.jpa.repository.JpaRepository; 
import nfy.sltraveller.model.Role; 


public interface RoleRepository extends JpaRepository<Role, Integer>{ 

} 

我试着使用@Repository anno也是。但它没有奏效。 为什么Spring无法识别存储库？

Answer 1

重新添加@Repository注释和库包添加到扫描列表

@ComponentScan({ "nfy.sltraveller.configuration", "nfy.sltraveller.repository" })
