SoapFaultClientException：找不到 header

Question

一個SOAP Web 服務，它接受以下格式的請求 -

<?xml version = "1.0"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV = "http://www.w3.org/2001/12/soap-envelope"
                   xmlns:ns="http://...." xmlns:ns1="http://...." xmlns:ns2="http://...."
                   xmlns:ns3="http://....">
    <SOAP-ENV:Header>
        <ns:EMContext>
            <messageId>1</messageId>
            <refToMessageId>ABC123</refToMessageId>
            <session>
                <sessionId>3</sessionId>
                <sessionSequenceNumber>2021-02-24T00:00:00.000+5:00</sessionSequenceNumber>
            </session>
            <invokerRef>CRS</invokerRef>
        </ns:EMContext>
    </SOAP-ENV:Header>
    <SOAP-ENV:Body>
        <ns1:getEmployee>
            <ns:empId>111</ns:empId>
        </ns1:getEmployee>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

當嘗試使用 JAXB2 向它發出 SOAP 請求時，它給出了org.springframework.ws.soap.client.SoapFaultClientException: EMContext Header is missing

我在用

啟動啟動器

spring-boot-starter-web 服務

org.jvnet.jaxb2.maven2：maven-jaxb2-plugin：0.14.0

和

客戶 -

public class MyClient extends WebServiceGatewaySupport {


    public GetEmployeeResponse getEmployee(String url, Object request){

        GetEmployeeResponse res = (GetEmployeeResponse) getWebServiceTemplate().marshalSendAndReceive(url, request);
        return res;
    }
}

配置 -

@Configuration
public class EmpConfig {

    @Bean
    public Jaxb2Marshaller marshaller(){
        Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
        jaxb2Marshaller.setContextPath("com.crsardar.java.soap.client.request");
        return jaxb2Marshaller;
    }

    @Bean
    public MyClient getClient(Jaxb2Marshaller jaxb2Marshaller){
        MyClient myClient = new MyClient();
        myClient.setDefaultUri("http://localhost:8080/ws");
        myClient.setMarshaller(jaxb2Marshaller);
        myClient.setUnmarshaller(jaxb2Marshaller);
        return myClient;
    }
}

應用程序 -

@SpringBootApplication
public class App {

    public static void main(String[] args) {

        SpringApplication.run(App.class, args);
    }

    @Bean
    CommandLineRunner lookup(MyClient myClient){

        return args -> {

            GetEmployeeRequest getEmployeeRequest = new GetEmployeeRequest();
            getEmployeeRequest.setId(1);
            GetEmployeeResponse employee = myClient.getEmployee("http://localhost:8080/ws", getEmployeeRequest);
            System.out.println("Response = " + employee.getEmployeeDetails().getName());
        };
    }
}

如何將 EMContext Header 添加到 SOAP 請求中？

Answer 1

服務器抱怨是因為您的 Web 服務客戶端未在您的 Z4DE361F0FCB49CDB3A 消息中發送EMContext SOAP header。

Unfortunately, currently Spring Web Services lack of support for including SOAP headers in a similar way as the SOAP body information is processed using JAXB, for example.

作為一種解決方法，您可以使用WebServiceMessageCallback 。 從文檔：

為了適應 SOAP 標頭的設置和消息上的其他設置，WebServiceMessageCallback 接口允許您在創建消息之后、發送之前訪問消息。

在你的情況下，你可以使用類似的東西：

public class MyClient extends WebServiceGatewaySupport {


  public GetEmployeeResponse getEmployee(String url, Object request){

    // Obtain the required information
    String messageId = "1";
    String refToMessageId = "ABC123";
    String sessionId = "3";
    String sessionSequenceNumber = "2021-02-24T00:00:00.000+5:00";
    String invokerRef = "CRS";

    GetEmployeeResponse res = (GetEmployeeResponse) this.getWebServiceTemplate().marshalSendAndReceive(url, request, new WebServiceMessageCallback() {

      @Override
      public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
        // Include the SOAP header content for EMContext
        try {
          SoapMessage soapMessage = (SoapMessage)message;
          SoapHeader header = soapMessage.getSoapHeader();
          StringSource headerSource = new StringSource(
            "<EMContext xmlns:ns=\"http://....\">" +
              "<messageId>" + messageId + "</messageId>" +
              "<refToMessageId>" + refToMessageId + "</refToMessageId>" +
              "<session>" +
                "<sessionId>" + sessionId + "</sessionId>" +
                "<sessionSequenceNumber>" + sessionSequenceNumber + "</sessionSequenceNumber>" +
              "</session>" +
              "<invokerRef>" + invokerRef + "</invokerRef>" +
            "</EMContext>"
          );

          Transformer transformer = TransformerFactory.newInstance().newTransformer();
          transformer.transform(headerSource, header.getResult());
        } catch (Exception e) {
          // handle the exception as appropriate
          e.printStackTrace();
        }
      }
    });
    return res;
  }
}
