我正在使用SpringBoot处理Spring 4应用程序。
在com.test.tm包中,
申请类:
@SpringBootApplication
@EnableJpaRepositories( repositoryFactoryBeanClass = GenericRepositoryFactoryBean.class )
@Import( { HikariDataSourceConfig.class } )
public class Application {
public static void main( String[] args )
{
SpringApplication.run(Application.class, args);
}
}
在com.test.tm.entities包中,
用户类:
@Table( name = "test.user" )
@Entity
public class User implements Serializable {
@Id
@GeneratedValue( strategy = GenerationType.AUTO )
private Integer id;
private String message;
....
}
在com.test.tm.user中 UserService.class:
@Service
@Transactional( rollbackFor = Exception.class )
public class UserService {
@Autowired
private GenericRepository<User, Serializable> gr;
public User saveEntity( User usr )
{
return gr.save(usr);
}
public String getUser()
{
//Get User logic
}
}
GenericRepository.java:
@NoRepositoryBean
public interface GenericRepository<T, ID extends Serializable> extends PagingAndSortingRepository<T, ID> {
public List<T> findByNamedQuery( String name );
public List<T> findByNamedQueryAndParams( String name, Map<String, Object> params );
}
还有一个GenericRepositoryImpl.java
,其中实现了上述方法的逻辑。
在运行Application.java时,我收到以下错误:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.test.utils.spring.repo.GenericRepository com.test.tm.user.UserService.gr; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type[com.test.utils.spring.repo.GenericRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.Dependency annotations: {@ org.springframework.beans.factory.annotation.Autowired(required = true) }
答案 0 :(得分:1)
广告。 1。
Spring使用默认名称创建image folder not created
bean,如documentation中所示。
广告。我当然没有起诉,但也许userService
不在
GenericRepositoryImpl
包裹?如果是,则使用适当的包声明指定其他com.test.tm
注释,例如。@ComponentScan
,或者 - 如果使用Boot 1.3+ - 修改@ComponentScan("com.test.utils")
