JAVA中的SOAP请求：无法添加包含SOAP命名空间中元素的片段

java xml soap

JAVA中的SOAP请求：无法添加包含SOAP命名空间中元素的片段,java,xml,soap,wsdl,soap-client,Java,Xml,Soap,Wsdl,Soap Client,我目前正在用Java编写一个独立的soap请求/响应应用程序，并使用以下项目：我使用此示例WSDL来开发代码：从上面的WSDL中，我试图调用操作：LatLonListCityNames 其中包含以下soap请求： <soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http:/

我目前正在用Java编写一个独立的soap请求/响应应用程序，并使用以下项目：

我使用此示例WSDL来开发代码：

从上面的WSDL中，我试图调用操作：LatLonListCityNames 其中包含以下soap请求：

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ndf="https://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl">
   <soapenv:Header/>
   <soapenv:Body>
      <ndf:LatLonListCityNames soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
         <displayLevel xsi:type="xsd:integer">1</displayLevel>
      </ndf:LatLonListCityNames>
   </soapenv:Body>
</soapenv:Envelope>

我不确定我在这里做错了什么。这里有什么指示吗

先谢谢你

再次感谢您。

您的代码存在多个潜在问题。在未来，你应该坚持一个特定的问题和/或错误，你的帖子，这样我们可以回答清楚

用WSDL实现SOAP API可能很棘手，因为涉及到太多的元素。关于第一个错误示例：“前缀ndf…未绑定”- 此错误表示您违反了为此SOAP API定义的XML架构。你不能那样做。您需要提供/绑定ndf前缀或调整模式。这将修复XML解析器错误。此问题很常见，您可以在此处找到更多信息：

代码中导致ndf错误的主要问题：这是由于您从以下位置删除了ndf架构声明：
