Mule - 安排流程以使用Web服务

我是Mule的新手,想做一件“简单”的事情:

  • 每隔X秒,调用一次soap webservice操作并将结果存储在一个文件中。

My Flow看起来真的像这样:

<?xml version="1.0" encoding="UTF-8"?>
    ...
    <custom-transformer class="net.cpy.samples.webservices.SampleMessage" name="MessageWs" doc:name="MessageWs"/>
    <flow name="csvPublisher" doc:name="csvPublisher">
        <quartz:inbound-endpoint jobName="job1" repeatInterval="5000" responseTimeout="10000" doc:name="Quartz">
            <quartz:event-generator-job/>
        </quartz:inbound-endpoint>
        <cxf:jaxws-client operation="getMessages" clientClass="net.cpy.samples.webservices.MessageServiceService" port="MessageServicePort" wsdlLocation="http://localhost:8080/webservices-0.0.1-SNAPSHOT/MessageService?wsdl" enableMuleSoapHeaders="true" doc:name="SOAP Client">
            <cxf:inInterceptors/>
            <cxf:outInterceptors/>
        </cxf:jaxws-client>
        <http:outbound-endpoint exchange-pattern="request-response" address="http://localhost:8080/webservices-0.0.1-SNAPSHOT/MessageService" doc:name="HTTP"/>
        <file:outbound-endpoint path="/tmp" outputPattern="output.xml" responseTimeout="10000" doc:name="File"/>
    </flow>
</mule>

我的示例Web服务的WSDL是:

    <?xml version='1.0' encoding='UTF-8'?><wsdl:definitions name="MessageServiceService" targetNamespace="http://webservices.samples.cpy.net/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://webservices.samples.cpy.net/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <wsdl:types>

<xs:element name="getMessages" type="tns:getMessages"/>
<xs:element name="getMessagesResponse" type="tns:getMessagesResponse"/>
<xs:element name="sampleMessage" type="tns:sampleMessage"/>

  </xs:complexType>
<xs:complexType name="getMessagesResponse">
    <xs:sequence>
      <xs:element maxOccurs="unbounded" minOccurs="0" name="return" type="tns:sampleMessage"/>
    </xs:sequence>
  </xs:complexType>
<xs:complexType name="sampleMessage">
    <xs:sequence>
      <xs:element minOccurs="0" name="content" type="xs:string"/>
      <xs:element minOccurs="0" name="date" type="xs:dateTime"/>
      <xs:element minOccurs="0" name="id" type="xs:long"/>
      <xs:element minOccurs="0" name="signature" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>
  </wsdl:types>
  <wsdl:message name="getMessagesResponse">
    <wsdl:part element="tns:getMessagesResponse" name="parameters">
    </wsdl:part>
  </wsdl:message>
  <wsdl:message name="getMessages">
    <wsdl:part element="tns:getMessages" name="parameters">
    </wsdl:part>
  </wsdl:message>
  <wsdl:portType name="MessageService">
    <wsdl:operation name="getMessages">
      <wsdl:input message="tns:getMessages" name="getMessages">
    </wsdl:input>
      <wsdl:output message="tns:getMessagesResponse" name="getMessagesResponse">
    </wsdl:output>
    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding name="MessageServiceServiceSoapBinding" type="tns:MessageService">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="getMessages">
      <soap:operation soapAction="" style="document"/>
      <wsdl:input name="getMessages">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="getMessagesResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="MessageServiceService">
    <wsdl:port binding="tns:MessageServiceServiceSoapBinding" name="MessageServicePort">
      <soap:address location="http://localhost:8080/webservices-0.0.1-SNAPSHOT/MessageService"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

目前,我尝试使用Quartz来安排Web服务调用, jaxws-client生成soap请求和http传输来调用服务。

我使用cxf从wsdl生成客户端代码。

有人可以给我一些建议,如何做到这一点?

我正在使用最新版本的mule(CE版)。

提前感谢您的帮助。

问题在于您没有在event-generator-job中指定有效负载,因此生成NullPayload,这可能会很快停止流程(无需发送)。

要么event-generator-job生成要用于CXF调用的对象。

或者,假设MessageWs转换器的工作是为CXF调用创建有效负载,让event-generator-job生成虚拟有效负载并让变换器用实际有效负载擦除它:

<flow name="csvPublisher" doc:name="csvPublisher">
    <quartz:inbound-endpoint jobName="job1" repeatInterval="5000" responseTimeout="10000" doc:name="Quartz">
        <quartz:event-generator-job>
            <quartz:payload>dummy</quartz:payload>
        </quartz:event-generator-job>
    </quartz:inbound-endpoint>
    <transformer ref="MessageWs" />
    <cxf:jaxws-client operation="getMessages" ...

您还可以使用Mule poll通过配置频率属性来安排流量。这里供您参考: - https://developer.mulesoft.com/docs/display/current/Poll+Reference
