概念性東東
webservice目的:異構平台之間的交互
JAX-WS:Java Api XML Web Service(基於JAVAAPI XML實現的WebService)
SEI:Service Endpoint Interface(實例中的IMyService)
SIB:Service Implements Bean(實例中的MyServiceImpl)
一個簡單的WebService實例
1 服務器的建立
1.1 創建接口
package com.lul.service;
import javax.jws.WebService;
@WebService()
public interface IMyService {
public int add(int a, int b);
public int minus(int a, int b);
}1.2 創建實現類
package com.lul.service;
import javax.jws.WebService;
@WebService(endpointInterface="com.lul.service.IMyService")
public class MyServiceImpl implements IMyService {
@Override
public int add(int a, int b) {
System.out.println(a+"+"+b+"="+(a+b));
return (a+b);
}
@Override
public int minus(int a, int b) {
System.out.println(a+"-"+b+"="+(a-b));
return (a-b);
}
}
1.3 開啟服務
package com.lul.service;
import javax.xml.ws.Endpoint;
public class MyService {
public static void main(String[] args){
String address="http://localhost:8888/ns";
Endpoint.publish(address,new MyServiceImpl());
}
}


2 客戶端的建立
package com.lul.service;
import java.net.MalformedURLException;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
public class TestClient {
public static void main(String[] args) {
try {
URL url=new URL("http://localhost:8888/ns?wsdl");
QName sname=new QName("http://service.lul.com/","MyServiceImplService");
Service service=Service.create(url, sname);
IMyService ms=service.getPort(IMyService.class);
System.out.println(ms.add(10, 9));
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}運行結果:
