Webservice是SOAP+XML，SOAP是基于Http的，Http底层是Socket，先回顾一下Socket：
Server：
public class Server { public static void main(String[] args) throws Exception { ServerSocket ss = new ServerSocket(6789); while(true){ Socket s = ss.accept(); InputStream is = s.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(is)); String str = br.readLine(); System.err.println("收到客户端消息："+str); br.close(); is.close(); s.close(); } }} Client：
public class Client { public static void main(String[] args) throws Exception { Socket s = new Socket("172.28.12.128",6789); OutputStream os = s.getOutputStream(); BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os)); bw.write("吃饭了某"); bw.close(); os.close(); s.close(); }} ++++++++++++++++++++++分割线+++++++++++++++++++++++++++++++++++++++++++++++++++++

WebService用的是SOAP协议：

使用jdk发布第一个WebService服务并调用

1，发布代码，新建java项目WS_01
package com.lhy.ws;import javax.jws.WebService;import javax.xml.ws.Endpoint;/** * @WebService:将 Java 类标记为实现 Web Service，或者将 Java 接口标记为定义 Web Service 接口。 */@WebServicepublic class HelloService { public String sayHello(String name){ return "Hello "+name; } public String sayByeBye(String name){ return "Bye bye "+name; } public static void main(String[] args) { /** * 参数1：服务的发布地址 * 参数2：服务的实现者 * publish 会新启动一个线程 */ Endpoint.publish("http://127.0.0.1:8889/hello", new HelloService()); System.err.println("publish是新开的线程监听客户端请求，所以这里能够输出"); }}
2，查看WSDL：WSDL－说明服务在哪里，如何调用，其实就是一个使用说明书
浏览器输入 http://127.0.0.1:8889/hello?wsdl
3，调用，wsimport命令生成客户端代码
这个命令为什么能执行？和java、javac一样，jdk/bin目录下有这个命令，只要配置了环境变量就能执行
找一个目录E:\杂项\WebService\client_code 在这里生成客户端代码
-s . 指定代码生成在当前目录，也可以自定义包名，加上参数 -p com.xxxx
生成的代码：
新建java项目，把客户端.java代码copy到项目
测试类APP：
package com.lhy.ws;/** * 通过wsimport生成客户端代码调用WebService服务 */public class App { public static void main(String[] args) { /** * WSDL: * */ HelloServiceService hss = new HelloServiceService(); /** * WSDL: * */ HelloService hs = hss.getHelloServicePort(); String result = hs.sayHello("NB"); System.err.println(result); //com.sun.proxy.$Proxy32 JDK动态代理生成的代理类 System.err.println(hs.getClass().getName()); }} 这个网站上有一些免费的服务可以调用，下边调用一下手机卡信息的服务
wsimport生成客户端代码
照着wsdl写代码：
public class MobileApp { public static void main(String[] args) { MobileCodeWS mobileCodeWS = new MobileCodeWS(); MobileCodeWSSoap mobileCodeWSSoap = mobileCodeWS.getMobileCodeWSSoap(); String result = mobileCodeWSSoap.getMobileCodeInfo("xxxxxxxx", ""); System.err.println(result); }}
