Question

我是网络服务的新手。我的要求是WSDL链接

我想动态查找所有支持的操作（方法由WSDL出版）
迭代列出的不同操作
动态获取参数列表并返回每个操作的值
在获取Operation Name，Param和return

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Name，为方法定义的参数，数据类型等。我已经创建了一个应用程序，它接受了WSDL并向我提供了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。任何示例代码/教程都非常感谢

附上客户的完整代码。

您需要使用wsdl2java-tool（使用axis2-zip打包）从给定的WSDL编译存根代码。然后，您将找到与您的Web服务相关的类，包括为您准备的所有方法，参数。
