Question

我创建了一个WSDL来创建一个问候语服务。下面给出的是WSDL。

我正在使用thsi wsdl创建一个生成并使用mule中的cxf：proxy-service公开Web服务。

这给了我错误。

请查看并帮助我解决此WSDL的问题。

    </wsdl:service>     
</wsdl:definitions>

如果我的WSDL出现问题，请帮助我。当我在mule cxf：proxy-service中使用它时，它无法正常工作。

FGiven下面是使用此WSDL公开服务的Mule Flow。

<flow name="WS_In">
    <http:inbound-endpoint address="http://localhost:8080/HelloService" exchange-pattern="request-response">
        <cxf:proxy-service  wsdlLocation="classpath:globalid3.wsdl" namespace="http://example.org/HelloService" service="ProxyService" />
    </http:inbound-endpoint>        
    <component>             
        <prototype-object class="com.example.ServiceProxy">                                                         
        </prototype-object>
    </component>        
    <echo-component></echo-component>
    <logger level="INFO"        />
</flow>

，错误是：

org.mule.api.lifecycle.LifecycleException: Lifecycle Manager 'WS_In.stage1' phase 'start' does not support phase 'dispose'
at org.mule.lifecycle.AbstractLifecycleManager.invokePhase(AbstractLifecycleManager.java:156)

Answer 1

您的WSDL中存在一个外壳问题。而不是：

  <wsdl:message name="greetingResponse">
    <wsdl:part type="tns:greeting" name="greetings"/>
  </wsdl:message>

你应该：

  <wsdl:message name="greetingResponse">
    <wsdl:part type="tns:Greeting" name="greetings"/>
  </wsdl:message>

通过这个修复，以下产生了一个从SOAPui调用时工作正常的Web服务：

<flow name="WS_In">
    <http:inbound-endpoint address="http://localhost:8080/HelloService"
        exchange-pattern="request-response">
        <cxf:proxy-service wsdlLocation="classpath:globalid3.wsdl"
            namespace="http://example.org/HelloService" service="ProxyService" />
    </http:inbound-endpoint>
    <custom-processor class="com.example.ServiceProxy" />
</flow>

消息处理器：

package com.example;

import javax.xml.namespace.QName;

import org.apache.commons.lang.StringEscapeUtils;
import org.mule.api.MuleEvent;
import org.mule.api.MuleException;
import org.mule.api.processor.MessageProcessor;

public class ServiceProxy implements MessageProcessor
{
    private final static QName SIMPLE_GREETING = new QName("http://example.org/HelloService",
        "simpleGreeting");

    public MuleEvent process(final MuleEvent event) throws MuleException
    {
        final QName operation = event.getFlowVariable("cxf_operation");

        if (operation.equals(SIMPLE_GREETING))
        {
            final String lastName = event.getMuleContext()
                .getExpressionLanguage()
                .evaluate("xpath('/lastName').text", event);

            final String responseXml = "<greetings><greet>Hi " + StringEscapeUtils.escapeXml(lastName)
                                       + "</greet></greetings>";

            event.getMessage().setPayload(responseXml);
            return event;
        }

        throw new UnsupportedOperationException(operation.getLocalPart() + " " + operation.getNamespaceURI()
                                                + " " + operation.getPrefix());
    }
}

有一种方法可以使用cxf：jaxws-service来完成此操作，但您需要生成服务类。看看here如何做到这一点。

之后，您可以以非常简单的方式配置服务。

        <cxf:jaxws-service
            serviceClass="mypackage.webservices.MyServicePortType"
            validationEnabled="false">
        </cxf:jaxws-service>

Answer 3

正在运行的流程如下。

<flow name="WS_In">
    <http:inbound-endpoint address="http://localhost:8080/HelloService" exchange-pattern="request-response">
            <cxf:proxy-service  wsdlLocation="classpath:helloservice.wsdl" namespace="http://example.org/HelloService" service="ProxyService" />
        </http:inbound-endpoint>        
        <component>             
            <prototype-object class="com.example.ServiceProxy">     
            </prototype-object>
        </component>        
        <echo-component></echo-component>
        <logger level="INFO"        />
 </flow>
