使用Camel生成soap請求

Question

我想使用wsdl文件從camel調用第三方web服務，而不使用任何生成客戶端代碼（因為我認為如果我提供wsdl文件，那么我們可以生成我們之前生成的客戶端，並且在我們的舊代碼中工作）

經過長時間的搜索，我找到了一些幫助我實現目標的代碼

代碼是

import org.apache.camel.CamelContext;
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.dataformat.soap.Soap11DataFormatAdapter;
import org.apache.camel.dataformat.soap.Soap12DataFormatAdapter;
import org.apache.camel.dataformat.soap.name.ServiceInterfaceStrategy;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.model.dataformat.SoapJaxbDataFormat;

import com.camel.model.Application;
public class TestMain {
    static CamelContext context;

    public static void main(String args[]) throws Exception {
        CamelContext context = new DefaultCamelContext();
        ProducerTemplate template = context.createProducerTemplate(0);
        context.start();
        String url="cxf://http://localhost:8081/buzzor-service/services/ApplicationService?" +
          "wsdlURL=http://localhost:8081/buzzor-service/services/ApplicationService?wsdl&" +
          "serviceName={http://service.application.buzzor.atpl.com}ApplicationService&" +
          "portName={http://service.application.buzzor.atpl.com}ApplicationServiceHttpPort&" +
          "dataFormat=MESSAGE";
        Exchange reply = sendSimpleMessage(template, url);
        org.apache.camel.Message out = reply.getOut();
        String result = out.getBody(String.class);

        System.out.println(result);
        Thread.sleep(10000);
        context.stop();
    }

    private static Exchange sendSimpleMessage(ProducerTemplate template,
            String endpointUri) {


        Exchange exchange = template.request(endpointUri, new Processor() {
            public void process(final Exchange exchange) throws Exception {

                exchange.getIn().setBody("<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
                         + "<soap:Body><ns1:getApplication xmlns:ns1=\"http://cxf.component.camel.apache.org/\">"
//                         + "<arg0 xmlns=\"http://cxf.component.camel.apache.org/\">hello world</arg0>"
                         + "</ns1:getApplication></soap:Body></soap:Envelope>");


                 System.out.println(exchange.getIn().getBody());
            }
        });
        return exchange;
    }
}

這工作正常，但在這里我手動生成肥皂信封

wsdl文件是

現在我想生成肥皂請求而不是靜態

請幫我

提前致謝

Answer 1

我改變了我的代碼如下現在它工作正常，但我想我沒有正確使用駱駝

所以幫助我使用camel改進生成soap請求而無需編寫任何java代碼。

package com.camel.test;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.xml.soap.MessageFactory;
import javax.xml.soap.MimeHeaders;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;

import org.apache.camel.CamelContext;
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.component.cxf.DefaultCxfBinding;
import org.apache.camel.component.cxf.common.message.CxfConstants;
import org.apache.camel.impl.DefaultCamelContext;

public class CamelViralTest {
    static CamelContext context;

    public static void main(String args[]) throws Exception {
        CamelContext context = new DefaultCamelContext();
        ProducerTemplate template = context.createProducerTemplate(0);

        context.start();
        String url = "cxf://http://localhost:8081/buzzor-service/services/ApplicationService?"
                + "wsdlURL=http://localhost:8081/buzzor-service/services/ApplicationService?wsdl&"
                + "serviceName={http://service.application.buzzor.atpl.com}ApplicationService&"
                + "portName={http://service.application.buzzor.atpl.com}ApplicationServiceHttpPort"
        +"&dataFormat=MESSAGE";
        Exchange e=sendSimpleMessage1(template,url);
        System.out.println(e.getOut().getBody());
        Thread.sleep(10000);
        context.stop();
    }

    private static Exchange sendSimpleMessage1(ProducerTemplate template,
            String endpointUri) {

        final List<String> params = new ArrayList<String>();
        Map<String, Object> headers = new HashMap<String, Object>();
        headers.put(CxfConstants.OPERATION_NAME, "getApplication");
        headers.put("requestObject", new DefaultCxfBinding());
        params.add("hello world");

        Exchange exchange = template.request(endpointUri, new Processor() {
            public void process(final Exchange exchange) throws Exception {
                SOAPMessage soapMessage=createSOAPRequest();
                exchange.getIn()
                        .setBody(  soapMessage.getSOAPBody());
            }
        });
        return exchange;

    }

    private static SOAPMessage createSOAPRequest() throws Exception {
         MessageFactory messageFactory = MessageFactory.newInstance();
            SOAPMessage soapMessage = messageFactory.createMessage();
            SOAPPart soapPart = soapMessage.getSOAPPart();

            String serverURI = "http://ws.cdyne.com/";

            // SOAP Envelope
            SOAPEnvelope envelope = soapPart.getEnvelope();
            envelope.addNamespaceDeclaration("example", serverURI);

            javax.xml.soap.SOAPBody soapBody = envelope.getBody();
            SOAPElement soapBodyElem = soapBody.addChildElement("getApplication", "example");
           /* SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("data", "example");
            soapBodyElem1.addTextNode("mutantninja@gmail.com");*/
            MimeHeaders headers = soapMessage.getMimeHeaders();
            headers.addHeader("SOAPAction", serverURI  + "getApplication");

            soapMessage.saveChanges();

            /* Print the request message */
            System.out.print("Request SOAP Message = ");
            soapMessage.writeTo(System.out);
            System.out.println();

            return soapMessage;
    }
}

Answer 2

如果您使用的是JAXB實體而不是String，則可以使用SOAP數據格式將其封送到SOAP信封中。 從那頁...

<route>
  <from uri="direct:start"/>
  <marshal>
     <soapjaxb contentPath="com.example.customerservice" version="1.2" elementNameStrategyRef="myNameStrategy"/>
  </marshal>
  <to uri="jms:myQueue"/>
</route>

一般來說，建議您手動編寫XML，因為它非常容易出錯而且您無法使用這些方便的功能。 您還會發現很難使用XPath以外的任何表達式語言來處理普通字符串。

Answer 3

1）讓我打電話給你的wsdl文件buzzor.wsdl 。 將wsdl保存在項目目錄中，如下所示，然后使用wsdl2java插件從wsdl文件生成類。 在你的pom.xml中添加這個。

<build>
<plugins>
    <plugin>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-codegen-plugin</artifactId>
    <version>3.1.0</version>
    <executions>
        <execution>
            <id>generate-sources</id>
            <phase>generate-sources</phase>
            <configuration>
                <sourceRoot>${project.build.directory}/generated-sources/cxf</sourceRoot>
                <wsdlOptions>
                    <wsdlOption>
                        <wsdl>${project.basedir}/src/main/resources/wsdl/buzzor.wsdl</wsdl>
                        <wsdlLocation>classpath:wsdl/buzzor.wsdl</wsdlLocation>
                         <extraargs>
                          <!--this will generate client for you-->
                            <extraarg>-client</extraarg>
                        </extraargs>
                   </wsdlOption>
                </wsdlOptions>
            </configuration>
            <goals>
                <goal>wsdl2java</goal>
            </goals>
        </execution>
    </executions>
</plugin>
</plugins>
</build> 

您將看到生成的類如下。

ApplicationServicePortType_ApplicationServiceHttpPort_Client.java是一個示例客戶端，您可以根據需要使用它來編寫自定義客戶端。

在您的情況下，讓我們使用ApplicationServicePortType.java來定義2個方法

a) public java.lang.String getApplication();
b) public http.model_application_buzzor_atpl.ApplicationResult addApplication(...);

2）在spring上下文中配置Jaxws客戶端。

<beans xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation="http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
    <jaxws:client id="applicationService" serviceClass="com.atpl.buzzor.application.service.ApplicationServicePortType" address="http://localhost:8081/buzzor-service/services/ApplicationService" />

3）在您的Camel路線中，您可以調用豆...

@Inject
private SoapUtils soapUtils;
...
from("direct:some-endpoint")
.bean(soapUtils,"invokeWebserviceAndGetResponse")

4）在SoapUtils類中，您可以注入applicationService bean並調用webservice

import com.atpl.buzzor.application.service.ApplicationServicePortType;
import http.model_application_buzzor_atpl.ApplicationResult;
import http.model_application_buzzor_atpl.Application;
import http.model_application_buzzor_atpl.User;
public class SoapUtils {
    @Inject
    private ApplicationServicePortType applicationService;

    public void invokeWebserviceAndGetResponse(Exchange exchange) {
         java.lang.String response = applicationService.getApplication();
         ..or..
         Application application = new Application(); //or whichever way you generate this.
         User user = new User(); //or which ever way u generate this.
         ApplicationResult result = applicationService.addApplication(application,user);
         ...
    }
}
