Spring @Configuration注解@Autowired服务为空

Spring @Configuration annotation @Autowired service is null

我正在使用 Spring 配置和 Jersey 配置。

这是我的spring配置:

@Component
@Configuration
@EnableScheduling
@EnableAspectJAutoProxy
@EnableTransactionManagement
@ComponentScan(basePackages = { "my.packages" })

public class SpringConfig {

private static final String MESSAGE_SOURCE_BASE_NAME = "i18n/messages";

@Profile(Profiles.APPLICATION)
@Configuration
@PropertySource("classpath:application.properties")
static class ApplicationProperties {
}

@Bean
public BCryptPasswordEncoder bCryptPasswordEncoder() {
    return new BCryptPasswordEncoder(11);
}

@Bean
public TaskScheduler taskScheduler() {
    return new ConcurrentTaskScheduler();
}

@Bean
MessageSource messageSource() {
    ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    messageSource.setBasename(MESSAGE_SOURCE_BASE_NAME);
    messageSource.setUseCodeAsDefaultMessage(true);
    return messageSource;
}

}

这是我的服务class和界面:

public interface DAOService {
    User register(User user)
}


@Service
public class DAOServiceImpl implements DAOService {

   @Override
   User register(User user){
      return null;
   }

 }

这是我的球衣资源:

ResourceSecurityService 内部 class 我想为 DAOService 使用@Autowire class,但我得到空指针异常,daoService 始终为空。

@Component
@Path("/security")
@Produces({ MediaType.APPLICATION_JSON })

public class ResourceDAOService  {

@Autowired 
private DAOService daoService ; //<--- here daoService is null;

@POST
@Path("/register")
@Consumes({ MediaType.APPLICATION_JSON })
@Transactional
public Response register(User user, @Context HttpServletRequest request,
        @Context HttpServletResponse response) throws AppException {
    return Response.status(Response.Status.CREATED).entity(securityService.register(user)).build();
}

我正在使用 spring 4.3 版。8.RELEASE 具有以下依赖项:

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>

        <artifactId>spring-orm</artifactId>
        <version>${spring.version}</version>
    </dependency>

如果你能为你的项目提供一个 link 会更好。 根据我看到的信息:

  • 确保你有 jersey-spring4 依赖性
  • 确保您的 Jersey 版本与集成依赖项兼容
  • 检查你的项目配置

我建议您使用 Spring 自动配置启动。
