为什么WSDL解析器仍然导入外部文档？

Question

我试图以API文档建议的方式关闭导入WSDL4J（1.6.2）中的文档：

  wsdlReader.setFeature("javax.wsdl.importDocuments", false);

实际上，它会停止导入使用wsdl：import标记声明的XML模式文件，但会停止导入使用xs：import标记声明的文件。

以下代码片段[请参阅信函末尾]以获取示例文件

http://www.ibspan.waw.pl/~gawinec/example.wsdl

返回以下异常：

javax.wsdl.WSDLException: WSDLException (at /definitions/types/xs:schema):
faultCode=OTHER_ERROR: An error occurred trying to resolve schema referenced
at 'EchoExceptions.xsd', relative to
'http://www.ibspan.waw.pl/~gawinec/example.wsdl'.:

    ... 10 more

你能建议我解决这个问题吗？我只是不想导入外部XML模式。

此致，Maciej

import javax.wsdl.WSDLException;
import javax.wsdl.factory.WSDLFactory;
import javax.wsdl.xml.WSDLReader;

public class IsolatedExample {
  public static void main(String[] args) {

    WSDLFactory wsdlFactory;
    try {
      wsdlFactory = WSDLFactory.newInstance();
      WSDLReader wsdlReader = wsdlFactory.newWSDLReader();
      wsdlReader.setFeature("javax.wsdl.verbose", false);
      wsdlReader.setFeature("javax.wsdl.importDocuments", false);
      wsdlReader.readWSDL("http://www.ibspan.waw.pl/~gawinec/example.wsdl");
    } catch (WSDLException e) {
      e.printStackTrace();
    }
  }
}

快速浏览一下WSDL4J（我直接使用这个项目已经有一段时间了）表明没有专门用来阻止读取导入模式的选项。您可能偶然发现了WSDL4J反序列化模式的错误。也就是说，如果您对任何模式的内容不感兴趣，包括在WSDL文档中内联的那些模式，您可以注册自己的扩展注册表（只需修改PopulatedExtensionRegistry类以省略SchemaDeserializer）。

具体来说，省略以下几行：

mapExtensionTypes(Types.class, SchemaConstants.Q_ELEM_XSD_1999,
    SchemaImpl.class);
registerDeserializer(Types.class, SchemaConstants.Q_ELEM_XSD_1999,
    new SchemaDeserializer());
registerSerializer(Types.class, SchemaConstants.Q_ELEM_XSD_1999,
    new SchemaSerializer());

mapExtensionTypes(Types.class, SchemaConstants.Q_ELEM_XSD_2000,
    SchemaImpl.class);
registerDeserializer(Types.class, SchemaConstants.Q_ELEM_XSD_2000,
    new SchemaDeserializer());
registerSerializer(Types.class, SchemaConstants.Q_ELEM_XSD_2000,
    new SchemaSerializer());

mapExtensionTypes(Types.class, SchemaConstants.Q_ELEM_XSD_2001,
    SchemaImpl.class);
registerDeserializer(Types.class, SchemaConstants.Q_ELEM_XSD_2001,
    new SchemaDeserializer());
registerSerializer(Types.class, SchemaConstants.Q_ELEM_XSD_2001,
    new SchemaSerializer());

我没有将Java用于Web服务，但您是否尝试过设置导入模式的绝对路径？也许它正在尝试加载本地文件。

你也可以尝试嗅探电线，看看你是否提出了要求，也许它是不正确的。
