我使用mule来公开Web服务。我已经构建了一个WSDL文件,我试图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。我使用Logger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>
所以基本上我想在ID,Name和行业节点中获取文本值并将它们映射到数据库表。有谁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,只放置了一个有效负载组件来从头部和主体中提取数据,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"?>

xml中的现在又报告了另一个错误: 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:// training / attributes:[] /&gt;] WARN 2015-01-22 12:22:39,850 [[ws-mule-cxf] .connector.http.mule.default.receiver.03] org.apache.cxf.phase.PhaseInterceptorChain:{http://training/的拦截器SF2DBService抛出异常,现在展开 org.apache.cxf.interceptor.Fault:无法将类org.dom4j.tree.DefaultElement转换为XMLStreamReader。
任何人都可以提供帮助吗?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>

使用带有SOAP连接器的Http Inbound,并配置了wsdl详细信息。
