Spring integration 调用SimpleWebServiceInboundGateway.invoke方法时出错

这是我第一次尝试使用Spring集成调用SOAP web服务。下面是我的bean配置类

    @Configuration
@EnableIntegration
@PropertySource(value = { "application.properties" })
public class SoapGatewayConfiguration {

    /**
     * URL mappings used by WS endpoints
     */
    public static final String[] WS_URL_MAPPINGS = { "/services/*", "*.wsdl", "*.xsd" };
    public static final String GATEWAY_INBOUND_CHANNEL_NAME = "wsGatewayInboundChannel";
    public static final String GATEWAY_OUTBOUND_CHANNEL_NAME = "wsGatewayOutboundChannel";

    @Bean
    public ServletWebServerFactory servletWebServerFactory() {
        TomcatServletWebServerFactory f = new TomcatServletWebServerFactory();
        f.setPort(9000);
        return f;
    }

    /**
     * Register the servlet mapper, note that it uses MessageDispatcher
     */
    @Bean
    public ServletRegistrationBean<MessageDispatcherServlet> messageDispatcherServlet(
            ApplicationContext applicationContext) {
        MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(applicationContext);
        servlet.setTransformWsdlLocations(true);
        servlet.setTransformSchemaLocations(true);
        servlet.setPublishEvents(true);
        ServletRegistrationBean<MessageDispatcherServlet> servletDef = new ServletRegistrationBean<>(servlet,
                WS_URL_MAPPINGS);
        servletDef.setLoadOnStartup(1);
        return servletDef;
    }

    /**

     */
    @Bean
    public MessageChannel wsGatewayInboundChannel() {

    }

    @Bean

        return MessageChannels.direct(GATEWAY_OUTBOUND_CHANNEL_NAME).get();
    }

    /**

            @Value("${spring.ws.should.track:true}") boolean shouldTrack) {
        SimpleWebServiceInboundGateway wsg = new SimpleWebServiceInboundGateway();
        wsg.setRequestChannel(wsGatewayInboundChannel());
        wsg.setReplyChannel(wsGatewayOutboundChannel());
        wsg.setExtractPayload(false); // Send the full RAW SOAPMessage and not just payload
        wsg.setLoggingEnabled(true);
        wsg.setShouldTrack(shouldTrack);
        wsg.setReplyTimeout(replyTimeout); // Do not believe this prop supported currently
        wsg.setRequestTimeout(requestTimeout); // Do not believe this prop is supported currently
        wsg.setCountsEnabled(true);
        return wsg;
    }

    /**
     * You must enable debug logging on
     * org.springframework.ws.server.endpoint.interceptor.PayloadLoggingInterceptor

        li.setLogResponse(true);
        li.setLogFault(true);
        return li;
    }

    /**
     * Validate the incoming web service against the schema
     *

    @Bean
    public AbstractValidatingInterceptor payloadValidatingInterceptor(XsdSchema xsdSchema,

    ) throws IOException {

        interceptor.setXsdSchema(xsdSchema);

        interceptor.setValidateResponse(soapValidateResponse);
        return interceptor;
    }

    @Bean
    public EndpointMapping uriEndpointMapping(PayloadValidatingInterceptor payloadValidatingInterceptor,
            SimpleWebServiceInboundGateway webServiceInboundGateway,
            SoapEnvelopeLoggingInterceptor loggingInterceptor) {
        UriEndpointMapping mapping = new UriEndpointMapping();
        mapping.setUsePath(true);
        mapping.setDefaultEndpoint(webServiceInboundGateway(1000L, 1000L, true));
        // mapping.setInterceptors({loggingInterceptor, payloadValidatingInterceptor});
        return mapping;
    }


    @Bean
    public Wsdl11Definition defaultWsdl11Definition() {
        SimpleWsdl11Definition wsdl11Definition = new SimpleWsdl11Definition();
        wsdl11Definition.setWsdl(new ClassPathResource("employees.wsdl.xml"));
        return wsdl11Definition;
    }

    /**
     * Expose the xsd at http://localhost:8080/services/mySchema.xsd
     **/
    @Bean
    public XsdSchema mySchema() {
        return new SimpleXsdSchema(new ClassPathResource("Employee.xsd"));
    }
}

问题：

需要建议我们是否需要在SOAP请求头中设置replyChannel&errorChannel属性？如果是，请告诉我怎么做

编辑1: 下面是@ServiceActivator端点的配置

@ServiceActivator(inputChannel = "wsGatewayOutboundChannel")
public void makeCall(Message<Employee> pr) {
    Employee response = pr.getPayload();
    System.out.println(response);
}

@ServiceActivator（inputChannel=“wsGatewayOutboundChannel”）
公共无效呼叫（消息pr）{
员工响应=pr.getPayload（）；
System.out.println（响应）；
}

您需要确保订阅了wsGatewayInboundChannel。这就是你得到例外的原因

换句话说，WS-Inbound Gateway向通道发送消息，但在通道的另一端没有什么可以处理的。

Hello Artem，我确实有一个@ServiceActivator端点配置为侦听wsGatewayOutboundChannel通道，该通道配置为SimpleWebServiceInboundGateway bean中的应答通道（如编辑1所示）。在错误消息中，它抱怨没有临时ReplyChannel的侦听器。我假设它会说wsGatewayOutboundChannel没有订户。请帮助我了解如何配置SimpleWebServiceInboundGateway以获得SOAP服务的响应。好吧，但我指的是

wsGatewayInboundChannel

-此网关发送消息的位置。基本上，您根本不需要回复通道，因为WS-gateway正在等待回复，但根本不发送消息。
