1、WebService工作原理-SOAP
?????? 当客户端调用一个WebService的方法时，首先将方法名称和需要传递的参数包装成XML，也就是SOAP包，通过HTTP协议传递到服务器端，然后服务器端解析这段XML，得到被调用的方法名称和传递过来的参数，进而调用WebService相应的方法，方法执行完毕后，将返回结果再次包装为XML，也就是SOAP响应，发送到客户端，最后客户端解析这段XML，最终得到返回结果。
2、WebService实现
?????? 创建WebService 项目
?????????????
?????? 创建WebService类
[java]
?
package service;?
?
import javax.jws.WebMethod;?
import javax.jws.WebService;?
import javax.xml.ws.Endpoint;?
??
@WebService?
public class Hello {?
?????
??? @WebMethod(operationName="sayHello1")?
??? public String sayHello(String userName)?
??? {?
??????? return "Hello,"+userName+"!";?
??? }?
?????
??? @WebMethod(operationName="sayHello2")?
??? public String sayHello(){?
??????? return "Hello World!";?
??? }?
??? public static void main(String[] args){?
??????? //将WebService发布到指定地址??
??????? Endpoint.publish("http://192.168.24.170:8888/WebServiceTest/Hello",new Hello());????????????
??? }?
}?
??
??package service;
??
??import javax.jws.WebMethod;
??import javax.jws.WebService;
??import javax.xml.ws.Endpoint;
??
??@WebService
??public class Hello {
???
???@WebMethod(operationName="sayHello1")
???public String sayHello(String userName)
???{
????return "Hello,"+userName+"!";
???}
???
???@WebMethod(operationName="sayHello2")
???public String sayHello(){
????return "Hello World!";
???}
???public static void main(String[] args){
????//将WebService发布到指定地址
????Endpoint.publish("http://192.168.24.170:8888/WebServiceTest/Hello",new Hello());???
???}
??}
?
?????? 编译Hello.java
?????????????
?????? 测试WebService是否发布成功
?????????????
?????????????
?????? 使用wsimport 生成客户端?
???
?????????? 使用如下：wsimport -p client -keep???????????????
???????????? 这时，会在当前目录中生成如下文件：
?????????????
?
?????? 创建客户端类[java]
public class HelloClient {?
??????????? public static void main(String args[]) {????
??????????????? HelloService service = new HelloService();????
??????????????? Hello helloProxy = service.getHelloPort();????
??????????????? String hello = helloProxy.sayHello1("世界");?
??????????????? System.out.println(hello);?
??????????????? String hello1 = helloProxy.sayHello2("");?
??????????????? System.out.println(hello1);??
??????????? }?
??????? }?
?????????
public class HelloClient {
???public static void main(String args[]) {??
????HelloService service = new HelloService();??
????Hello helloProxy = service.getHelloPort();??
????String hello = helloProxy.sayHello1("世界");
????System.out.println(hello);
????String hello1 = helloProxy.sayHello2("");
????System.out.println(hello1);
???}
??}
??
????????????? 运行结果如下
