Question

美好的一天！

我最近才开始研究ESB总线。我需要使用Content-Type转换HTTP请求中的传入SOAP消息：application / x-www-form-urlencoded。

我在Java中创建了一个代理服务，自定义中介1，转换了消息，如何将其传递到端点并在Custom Mediator 2中获得答案？

在图片中，我画了一个如何转换信息的例子。

Answer 1

您不需要编写自定义调解器，您可以将SOAP转换为其余调用，使用等待2个参数的休息服务进行采样，例如

参数1 =值1＆安培; param2的=值2

<!-- prepare data for org.apache.axis2.transport.http.XFormURLEncodedFormatter message formatter -->
<payloadFactory media-type="xml">
    <format> 
        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> 
            <soapenv:Body> 
                <root> 
                    <param1>$1</param1> 
                    <param2>$2</param2> 
                </root> 
            </soapenv:Body> 
        </soapenv:Envelope> 
    </format> 
    <args> 
        <arg evaluator="xml" expression="$body/node1/node11/text()"/> 
        <arg evaluator="xml" expression="$body/node1/node12/text()"/> 
   </args> 
</payloadFactory>  

<!-- set output format -->

<property name="messageType" value="application/x-www-form-urlencoded" scope="axis2" type="STRING"/> 
<property name="DISABLE_CHUNKING" value="true" scope="axis2" type="STRING"/> 

<!-- call the REST endpoint with synch call : response is received in this sequence -->

<call> 
   <endpoint key="conf:endpoints/MyServiceEndpoint.xml"/> 
</call> 

<!-- the response is here, transform it has needed -->
<xslt key="myxsl"/>

<!-- send this response to the client -->
<property name="messageType" value="application/soap+xml" scope="axis2" type="STRING"/>  
<!-- or test/xml and in this case, don't forget to specify a SOAP Action, below, a sample to specify a blank soapAction : -->
<header name="Action" value="&quot;&quot;"/>
<send/>

示例端点conf（使用此示例，您需要在序列中定义属性uri.var.ServiceURL）：

<endpoint>
  <http method="POST" uri-template="{uri.var.ServiceURL}/Path/2011-10-01"/>
</endpoint>

但如果您真的需要自定义调解器，只需将payloadFactory和xslt调解器替换为它们

感谢您的回复，我仍然需要编写自定义中介，只需要一个非常复杂的转换消息我将举例说明如何转换消息

我的代理服务中的SOAP消息，发送到custrom mediator

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <AddPay xmlns="http://MyTestService">
      <!--input dynamic data-->
      <fields>
        <Items>
          <Data>
            <Name>Field1</Name>
            <Value>11</Value>
          </Data>
          <Data>
            <Name>Field2</Name>
            <Value>22</Value>
          </Data>
        </Items>
      </fields>
    </AddPay>
  </soap:Body>
</soap:Envelope>
