Question

我已从现有的WSDL文件创建了SpringBoot CXF soap服务。我现在可以从springboot应用程序的嵌入式tomcat上运行的服务访问WSDL。当我尝试从soap-ui向服务发送请求时，控件到达服务方法的实现，然后当它访问@Autowired服务层时，它会抛出所有NPE，因为服务对象为null（我有在调试时看到这个）。如果我通过注释@Autowired对象手动创建（new Service（）），流可以到达服务实现，然后DAO对象失败，因为它无法@Autowire DAO Impl，进一步当我创建手动DAO Impl对象时在@PersistenceContext失败，因为实体管理器为空。

我已确保服务使用@Service，带有@Repository的DAO层注释，但问题仍然存在。我还添加了@ComponentScan并提供了所有的包名，但我仍然为所有@Autowired获取null。

以下代码：配置类

@SpringBootApplication
public class EmWebSvcBootApplication extends SpringBootServletInitializer{

public static void main(String[] args) {
    SpringApplication.run(EmWebSvcBootApplication.class, args);
}

public static final String SERVICE_NAME_URL_PATH = "/em";
public static final String EM_ISSUER_SERVICE_NAME_URL_PATH = "/EntitlementIssuer";


@Bean(name=Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {      
    return new SpringBus();
}


@Bean
public ServletRegistrationBean cxfServlet() {
    ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new CXFServlet(), SERVICE_NAME_URL_PATH + "/*");
    // Add custom Title to CXF´s ServiceList
    Map<String, String> initParameters = servletRegistrationBean.getInitParameters();
    initParameters.put("service-list-title", "My Test service");
    return servletRegistrationBean;
}

@Bean
public Endpoint endpoint() {
    EndpointImpl endpoint = new EndpointImpl(springBus(), new EntitlementIssuerEndpointImpl());
    endpoint.setServiceName(entitlementIssuer_Service().getServiceName());
    endpoint.setWsdlLocation(entitlementIssuer_Service().getWSDLDocumentLocation().toString());
    endpoint.publish(EM_ISSUER_SERVICE_NAME_URL_PATH);
    return endpoint;
}

 @Bean EntitlementIssuer_Service entitlementIssuer_Service(){
     return new  EntitlementIssuer_Service();
 }

}

服务类：

@Service
public class EntitlementIssuerServiceImpl implements EntitlementIssuerService {

private static final Logger logger = LoggerFactory.getLogger(EntitlementIssuerServiceImpl.class);

@Autowired
private EntitlementIssuerDAO entitlementIssuerDAO;

@Transactional(readOnly=true)
public List<EntitlementIssuerResponseWrapper> getEntitlementIssuers(EntitlementIssuerRequestWrapper requestWrapper)
        throws EMSystemException, EMBusinessException {

try{
            daoResponse = entitlementIssuerDAO.findEntitlementIssuers(requestWrapper);
        }catch(Throwable t){
        logger.error("Error while getting entitlement issuers: " + t.getMessage());
        throw new EMSystemException("Error while getting entitlement issuers: " + t.getMessage());
    }

}

DAO层：

@Repository
public class EntitlementIssuerDaoImpl implements EntitlementIssuerDAO{

    @PersistenceContext
private EntityManager entityManager;

public EntityManager getEntityManager() {
    return entityManager;
}

@Override
public List<EntitlementIssuer> findEntitlementIssuers(EntitlementIssuerRequestWrapper request) {

    Session session = (Session) entityManager.getDelegate();
    Criteria criteria = session.createCriteria(EntitlementIssuer.class, "entitlementIssuer");

    setupCriteria(request,criteria);
    List<EntitlementIssuer> output = criteria.list();
    return output;

}
}

我已添加了我正在使用的所有配置，我们非常感谢任何帮助解决此问题。基本上所有@Autowired服务，数据层和实体管理器都没有加载（因为我在调试中看到它们为null）。

我已经能够根据来自 https://github.com/codecentric/cxf-spring-boot-starter

的信息解决问题

/**
 * Configuration of SOAP Web services
 */
@Configuration
public class EntitlementIssuerServiceSOAPConfig {

    @Autowired
    private Bus bus;

    @Bean
    public EntitlementIssuerService getEntitlementIssuerServiceWebServiceImpl() {
        return new EntitlementIssuerServiceWebServiceImpl();
    }

    @Bean (name = "EntitlementIssuerServiceWebService")
    public Endpoint endpoint() {
        EndpointImpl endpoint = new EndpointImpl(bus, getEntitlementIssuerServiceWebServiceImpl());
        endpoint.publish("/EntitlementIssuerService");
        return endpoint;
    }

}

@Autowired在SpringBoot CXF应用程序中提供空指针异常
