wsdl和soap协议详细解析

1.服务端：

package zhou;import javax.jws.WebService;/** 可写成接口形式去实现* 实现类必须指定接口包路径* @WebService(endpointInterface = "...")* */@WebService(targetNamespace = "http://192.168.0.108:8099/hello")public class PersonService {public String sayHello(String name) {return name + "hello";}}

2.启动服务端调用：

import zhou.PersonService;import javax.xml.ws.Endpoint;public class Publisher {public static void main(String[] args) {Endpoint publish = Endpoint.publish("http://192.168.0.108:8099/hello", new PersonService());}}
