WSDL4J解析WSDL 获取方法

WSDL4J是用于解析WSDL文档的Java API。下面是使用WSDL4J获取方法的步骤：

1. 首先，您需要将WSDL文档读入到org.apache.ws.commons.schema.utils.DOMUtil类的Document对象中。例如：

URL wsdlURL = new URL("http://example.com/MyService?wsdl");
Document doc = DOMUtil.parse(wsdlURL.openStream());

2. 创建WSDLReader对象并使用它来读取WSDL文档：

WSDLFactory factory = WSDLFactory.newInstance();
WSDLReader reader = factory.newWSDLReader();
Definition wsdlDefinition = reader.readWSDL(wsdlURL.toString(), doc);

3. 获取服务(Service)和端口(Port)：

Map services = wsdlDefinition.getServices();
Service service = (Service) services.values().iterator().next();
Map ports = service.getPorts();
Port port = (Port) ports.values().iterator().next();

4. 获取操作(Operation)和消息(Message)：

Binding binding = port.getBinding();
List operations = binding.getBindingOperations();
BindingOperation operation = (BindingOperation) operations.get(0);
Operation op = operation.getOperation();
Input input = op.getInput();
List messages = input.getMessage().getOrderedParts(null);
Message message = (Message) messages.get(0);

5. 获取操作的输入(Input)和输出(Output)消息的元素(Element)：

Part part = message.getPart("partName");
QName elementQName = part.getElementName();
Element element = wsdlDefinition.getTypes().getElement(elementQName);

6. 获取元素(Element)的类型(Type)：

XmlSchemaType schemaType = null;
if (element != null) {
    schemaType = element.getSchemaType();
}
