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();
}

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。
