Question

我是Spring框架的新手，我在使用Spring创建一个简单的SOAP客户端时遇到了一些问题。

就像一个好新手一样，我使用Spring教程来创建我的SOAP客户端。你可以在这里找到它 - ＆gt; https://spring.io/guides/gs/consuming-web-service/

使用示例中给出的Web服务测试是可以的。我已经更改了代码以使其适用于我的Web服务，因此这是文件：

SetCodePinConfigurartion.java

package hello;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;

@Configuration
public class SetPinCodeConfiguration {

@Bean
public Jaxb2Marshaller marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    // this package must match the package in the <generatePackage> specified in
    // pom.xml
    marshaller.setContextPath("hello.wsdl");
    return marshaller;
}

@Bean
public SetPinCodeClient SetPinCodeClient(Jaxb2Marshaller marshaller) {
    SetPinCodeClient client = new SetPinCodeClient();
    client.setDefaultUri("http://xxx.xxx.xx.x/PlayerServices/PlayerIntelligence/PlayerManagementService");
    client.setMarshaller(marshaller);
    client.setUnmarshaller(marshaller);
    return client;
}
}

SetPinCodeClient.java

package hello;

import javax.xml.bind.JAXBElement;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import org.springframework.ws.soap.client.core.SoapActionCallback;

import hello.wsdl.SetPinCode;
import hello.wsdl.SetPinCodeResponse;

public class SetPinCodeClient extends WebServiceGatewaySupport{

private static final Logger log = LoggerFactory.getLogger(SetPinCodeClient.class);

public SetPinCodeResponse SetPinCode(JAXBElement<String> pinCode, JAXBElement<String> cardNumber, JAXBElement<Integer> casinoCreationId) {

    SetPinCode request = new SetPinCode();
    request.setPinCode(pinCode);
    request.setCardNumber(cardNumber);
    request.setCasinoCreationId(casinoCreationId);

    log.info("Requesting save in database for card " + cardNumber + "with pin code" + pinCode + "from casino n°" + casinoCreationId);

    SetPinCodeResponse response = (SetPinCodeResponse) getWebServiceTemplate()
            .marshalSendAndReceive("http://xxx.xxx.xx.x/PlayerServices/PlayerIntelligence/PlayerManagementService",
                    request,
                    new SoapActionCallback("http://xxx.xxx.xx.x/PlayerServices/PlayerIntelligence/PlayerManagementService/SetPinCode"));

    return response;
}
}

Application.java

package hello;

import javax.xml.bind.JAXBElement;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import hello.wsdl.ObjectFactory;
import hello.wsdl.SetPinCodeResponse;

@SpringBootApplication
public class Application {

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

@Bean
CommandLineRunner lookup(SetPinCodeClient setPinCodeClient) {
    return args -> {
        JAXBElement<String> pinCode = new ObjectFactory().createSetPinCodeCardNumber("2004");
        JAXBElement<String> cardNumber = new ObjectFactory().createSetPinCodeCardNumber("B09B036");
        JAXBElement<Integer> casinoCreationId = new ObjectFactory().createSetPinCodeCasinoCreationId(185);

        SetPinCodeResponse response = setPinCodeClient.SetPinCode(pinCode, cardNumber, casinoCreationId);
        System.err.println(response.toString());
    };
}
}

但是当我使用该应用程序时出现错误

java.lang.IllegalStateException: Failed to execute CommandLineRunner

所以我似乎需要更改SOAP 1.2的协议，但我找不到正确的方法。我已经在 SetPinCodeClient.java

中测试了这个解决方案

public SetPinCodeResponse SetPinCode(JAXBElement<String> pinCode, JAXBElement<String> cardNumber, JAXBElement<Integer> casinoCreationId) {

    SetPinCode request = new SetPinCode();
    request.setPinCode(pinCode);
    request.setCardNumber(cardNumber);
    request.setCasinoCreationId(casinoCreationId);

    log.info("Requesting save in database for card " + cardNumber + "with pin code" + pinCode + "from casino n°" + casinoCreationId);

    SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory();
    messageFactory.setSoapVersion(SoapVersion.SOAP_12);
    WebServiceTemplate wsTemplate = getWebServiceTemplate();
    wsTemplate.setMessageFactory(messageFactory);

    SetPinCodeResponse response = (SetPinCodeResponse) wsTemplate
            .marshalSendAndReceive("http://192.168.67.63:8095/PlayerServices/PlayerIntelligence/PlayerManagementService",
                    request,
                    new SoapActionCallback("http://192.168.67.63:8095/PlayerServices/PlayerIntelligence/PlayerManagementService/SetPinCode"));

    return response;
}

但是，如果我这样做，它会将protocal更改为SOAP 1.2但是在

之后我有这个错误

NullPointerException，因为我的对象messageFactory为NULL ....

所以问题是，我如何才能改进SOAP 1.2的好方法？谢谢你的回答。

Answer 1

还有一种更简单的方法来启用 SOAP 1.2 支持，这类似于为您的客户端设置编组器的方式。只需使用正确的 SOAP 版本创建一个 WebServiceMessageFactory bean：

@Bean
WebServiceMessageFactory messageFactory()
{
    SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory();
    messageFactory.setSoapVersion(SoapVersion.SOAP_12);
    return messageFactory;
}

您只需要将上述 bean 添加到您的配置类中，将其作为参数传递给您的客户端 bean，然后调用 setMessageFactory(..)：

@Configuration
public class SetPinCodeConfiguration
{
    @Bean
    public Jaxb2Marshaller marshaller()
    {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        // this package must match the package in the <generatePackage> specified in
        // pom.xml
        marshaller.setContextPath("hello.wsdl");
        return marshaller;
    }

    @Bean
    public SetPinCodeClient SetPinCodeClient(Jaxb2Marshaller marshaller, WebServiceMessageFactory messageFactory)
    {
        SetPinCodeClient client = new SetPinCodeClient();
        client.setDefaultUri("http://xxx.xxx.xx.x/PlayerServices/PlayerIntelligence/PlayerManagementService");
        client.setMessageFactory(messageFactory); // <-- set the message factory
        client.setMarshaller(marshaller);
        client.setUnmarshaller(marshaller);
        return client;
    }
}

所以我终于找到了一种使用SOAP 1.2协议进行调用的方法。

以下是 SetPinCodeClient.java的完整代码

package hello;

import javax.xml.bind.JAXBElement;
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPConstants;
import javax.xml.soap.SOAPException;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.ws.WebServiceMessage;
import org.springframework.ws.client.core.WebServiceTemplate;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import org.springframework.ws.soap.SoapHeader;
import org.springframework.ws.soap.SoapHeaderElement;
import org.springframework.ws.soap.client.core.SoapActionCallback;
import org.springframework.ws.soap.saaj.SaajSoapMessage;
import org.springframework.ws.soap.saaj.SaajSoapMessageFactory;

import hello.wsdl.SetPinCode;
import hello.wsdl.SetPinCodeResponse;

public class SetPinCodeClient extends WebServiceGatewaySupport{

private static final Logger log = LoggerFactory.getLogger(SetPinCodeClient.class);

public SetPinCodeResponse SetPinCode(JAXBElement<String> pinCode, JAXBElement<String> cardNumber, JAXBElement<Integer> casinoCreationId) throws SOAPException {
    String action ="http://tempuri.org/Player_x0020_Management_x0020_Service/SetPinCode";
    String uri = "http://xxx.xxx.xx.x/PlayerServices/PlayerIntelligence/PlayerManagementService";

    SetPinCode request = new SetPinCode();
    request.setPinCode(pinCode);
    request.setCardNumber(cardNumber);
    request.setCasinoCreationId(casinoCreationId);

    log.info("Requesting save in database for card " + cardNumber + "with pin code" + pinCode + "from casino n°" + casinoCreationId);

    MessageFactory msgFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
    SaajSoapMessageFactory saajSoapMessageFactory = new SaajSoapMessageFactory(msgFactory);
    WebServiceTemplate wsTemplate = getWebServiceTemplate();
    wsTemplate.setMessageFactory(saajSoapMessageFactory);

    SoapActionCallback requestCallback = new SoapActionCallback(action) {
        public void doWithMessage(WebServiceMessage message) {
            SaajSoapMessage soapMessage = (SaajSoapMessage) message;
            SoapHeader soapHeader = soapMessage.getSoapHeader();

            QName wsaToQName = new QName("http://www.w3.org/2005/08/addressing", "To", "wsa");
            SoapHeaderElement wsaTo =  soapHeader.addHeaderElement(wsaToQName);
            wsaTo.setText(uri);

            QName wsaActionQName = new QName("http://www.w3.org/2005/08/addressing", "Action", "wsa");
            SoapHeaderElement wsaAction =  soapHeader.addHeaderElement(wsaActionQName);
            wsaAction.setText(action);
        }
    };

    SetPinCodeResponse response = (SetPinCodeResponse) wsTemplate.marshalSendAndReceive(uri, request, requestCallback);

    return response;


}
}

在Spring中将SOAP 1.2与WebServiceGatewaySupport一起使用
