我是网络服务的新手。我的要求是一个 WSDL 链接
- 我想动态查找所有支持的操作（WSDL 发布的方法）
- 迭代列出的不同操作
- 动态获取每个操作的参数列表和返回值
- 获取到Operation Name、Param的详细信息后动态消费一个Service并返回
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 并给我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。
