4.补充：如果运行客户端中以下代码可以正常运行
public static void main(String[] args) {
//调用webservice
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(IHelloWorldService.class);
factory.setAddress("http://172.16.3.61:9000/helloWorld");

IHelloWorldService service = (IHelloWorldService) factory.create();
System.out.println("[result]" + service.sayHello("chain"));
}
运行结果：
