通过JDK自带API发布webservice
首先，webservice是通过接口进行发布的
package com.nomouse.webservice;import javax.jws.WebService;@WebServicepublic interface HelloWorld {String sayHi(String text);} 然后是实现
package com.nomouse.webservice;import javax.jws.WebService;@WebService(endpointInterface = "com.nomouse.webservice.HelloWorld")public class HelloWorldImpl implements HelloWorld {public String sayHi(String text) {System.out.println("sayHi called");return "Hello " + text;}} 最后是发布
package com.nomouse.webservice;import javax.xml.ws.Endpoint;public class Test {public static void main(String[] args) {Endpoint.publish(":8080/hello", new HelloWorldImpl());}} 这样，我们就在这个地址:8080/hello 发布了一个webservice，我们通过浏览器访问:8080/hello?wsdl，可以获取到一个xml文件，那么webservice发布就成功了。
java中调用其他系统发布的webservice
以我们上面发布的webservice为例，首先我们要获知webservice发布的地址，既上面的:8080/hello?wsdl，，然后我们用JDK自带的wsimport工具生成webservice客户端代码，在cmd命令行下输入wsimport -keep :8080/hello?wsdl，然后我们可以看到在当前cmd目录下生成一个com目录，把目录连同里边的java文件导入到客户端项目中。
然后我们开始编写客户端代码如下：
package com.nomouse.webservice;public class Client {public static void main(String[] args) {HelloWorldImplService service = new HelloWorldImplService();HelloWorld client = service.getHelloWorldImplPort();String result = client.sayHi("nomouse");System.out.println(result);}} 控制台输出：Hello nomouse，说明我们调用成功。
用cxf +spring发布webservice
用JDK原生方法生成webservice固然简单，但是不好与我们自己的web系统集成，在项目中，我们更多地使用一些成熟的java webservice框架进行webservice发布，在这里我用cxf框架结合spring进行webservice发布，使用maven做项目构建，jetty作为web服务器。
第一步，用pom文件构建项目结构，项目名为webservice

我们人生中最大的懒惰，就是当我们明知自己拥有作出选择的能力，
