如何从 mule 中的 Web 服务获取数据

how to get data from web service in mule

我正在使用 mule 公开 Web 服务。我已经构建了一个 WSDL 文件,我正在尝试从消息中获取文本以加载到数据库中,但我不知道如何获取文本。我正在使用 Logger 来记录我的有效负载,如下所示。

INFO  2015-01-20 11:00:54,470 [[ws-mule-cxf].connector.http.mule.default.receiver.03] org.mule.api.processor.LoggerMessageProcessor: <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tra="http://training/">
   <soapenv:Header/>
   <soapenv:Body>
      <tra:sayHi>
         <!--Optional:-->
         <ID>111</ID>
         <!--Optional:-->
         <name>John</name>
         <!--Optional:-->
         <industry>IT</industry>
         <!--Optional:-->
         <REF/>
      </tra:sayHi>
   </soapenv:Body>
</soapenv:Envelope>

所以基本上我想获取 ID、名称和行业节点中的文本值并将它们映射到数据库 table。任何人请让我知道如何编写代码来获取这些信息?谢谢!

现在我删除了数据库连接器部分,只放置了一组有效负载组件以从 header 和 body 中提取数据以检查 xpath 是否正常工作,但它不能。

配置XML在这里:

<?xml version="1.0" encoding="UTF-8"?>

        <logger message="#[payload]" level="INFO" doc:name="Logger"/>
    </flow>
</mule>

错误信息是:

表达式 "xpath('//soapenv:Envelope/soapenv:Body/*')" 的执行失败。 (org.mule.api.expression.ExpressionRuntimeException)。消息负载的类型为:String

**更新:我添加了

  <mulexml:namespace-manager includeConfigNamespaces="true">
    <mulexml:namespace prefix="soapenv" uri="http://schemas.xmlsoap.org/soap/envelope/"/>
    <mulexml:namespace prefix="tra" uri="http://training/"/>
  </mulexml:namespace-manager>

在 xml 中,现在它报告另一个错误: INFO 2015-01-22 12:22:39,847 [[ws-mule-cxf].connector.http.mule.default.receiver.03] org.mule.api.processor.LoggerMessageProcessor: org.dom4j.tree.DefaultElement@4586a9c5 [元素: http: //训练/属性:[]/>] WARN 2015-01-22 12:22:39,850 [[ws-mule-cxf].connector.http.mule.default.receiver.03] org.apache.cxf.phase.PhaseInterceptorChain:{http://training/}SF2DBService 的拦截器抛出异常,现在放松 org.apache.cxf.interceptor.Fault: 无法将 class org.dom4j.tree.DefaultElement 转换为 XMLStreamReader.

有人可以帮忙吗?谢谢! **

您需要使用Database connector,看看它是如何工作的。您通常会使用参数化查询。并使用 MEL 的 XPath 支持。像这样:

<your-inbound-endpoint-here.../>
<set-variable variableName="id" value="#[xpath('//Body/sayHi/ID').text]"/>
<set-variable variableName="name" value="#[xpath('//Body/sayHi/name')]"/>
<set-variable variableName="industry" value="#[xpath('//Body/sayHi/industry')]"/>
<db:template-query name="insert">
  <db:parameterized-query>
    <![CDATA[
      INSERT INTO YOUR_TABLE("ID", "NAME", "INDUSTRY") VALUES (:id, :name, :industry);
    ]]>
  </db:parameterized-query>
  <db:in-param name="id" defaultValue="#[id"/>
  <db:in-param name="name" defaultValue="#[name]"/>
  <db:in-param name="industry" defaultValue="#[industry]"/>
</db:template-query>

将 Http Inbound 与配置了 wsdl 详细信息的 SOAP 连接器结合使用。
