这里有一个service 叫HelloServiceImplService
它有一个port 叫HelloService1Port
这个port的地址是location
这个port绑定的类是HelloService1
这个类有一个方法say

整体阅读应该是由下往上看
tns 为 target name space

// String namespaceURI, String localPart
QName qname = new QName("http://impl.service.zno.cn/","HelloServiceImplService");
        
Service service = Service.create(new URL("http://localhost:8080/hello?wsdl"),qname);
HelloService1 serv = service.getPort(HelloService1.class);
serv.say("hi");
