动态客户端 WSDL

Question

我是网络服务的新手。我的要求是一个 WSDL 链接

1. 我要动态查找所有支持的操作（方法 由 WSDL 发布）
2. 迭代列出的不同操作
3. 动态获取每个操作的参数列表和返回值
4. 获取Operation Name、Param和return的详细信息后动态消费一个Service

我能够编写一个动态客户端应用程序（Axis 2，WSDL4J），它将使用 WSDL 并给出方法名称、为方法定义的参数、数据类型等。 我创建了一个应用程序，它采用 WSDL 并为我提供 WSDL 中存在的所有方法。

Definition def = reader.readWSDL(null, wsdlURI);
Map services = def.getServices();
// Services when Iterated will give all the Method Names 
// .......
Operation operation = boperation.getOperation();
String OperationName = operation.getName();
System.out.println("OperationName :" + OperationName.toString());

除此之外，我不确定如何动态获取给定方法的参数名称。 非常感谢任何示例代码/教程

附上客户端的完整代码。

    public class DynamicInvoke {

    public static void main(String[] args) throws WSDLException {

        String wsdlURI = "WORKING_WSDL_LINK";
        DynamicInvoke di = new DynamicInvoke();
        List wsdlList = new ArrayList();

        wsdlList = di.buildComponents(wsdlURI);

    }

    public List buildComponents(String wsdlURI) throws WSDLException {
        // The list of components that will be returned
        List serviceList = Collections.synchronizedList(new ArrayList());

        // Create the WSDL Reader object
        WSDLFactory factory = WSDLFactory.newInstance();
        WSDLReader reader = factory.newWSDLReader();

        try {
            // Read the WSDL and get the top-level Definition object
            Definition def = reader.readWSDL(null, wsdlURI);

                    // Add the new component to the List to be returned
                    serviceList.add(serviceInfo);
                }

        while (portIter.hasNext()) {

            // Get the Port's Binding
            javax.wsdl.Binding binding = port.getBinding();

            // Now we will create operations from the Binding information
            List operations = buildOperations(binding);

            // Process methods built from the binding information

                String OperationName = operation.getName();
                System.out.println("OperationName :" + OperationName.toString());

                Input inDef = operation.getInput();
                String ParamName = inDef.getName();
                System.out.println("inDef--->" + ParamName);
                Message inMessage = inDef.getMessage();
                Map parts = inMessage.getParts();


                System.out.print("\nAxis parameters gathered:\nTargetNamespace = " +"\n"+
                        "Service Name = "+namespace.toString() +"\n"+

            }
        }

        return component;
    }

    private List buildOperations(Binding binding) {
        // TODO Auto-generated method stub

        List list = binding.getBindingOperations();

        System.out.println("Bindings :" + list);
        return list;

    }

}

您需要使用 wsdl2java-tool（它与 axis2-zip 打包在一起）从给定的 WSDL 编译存根代码。 然后你会发现你的 web 服务相关的类，包括所有的方法，为你准备好参数。
