java實現(xiàn)簡單的webservice方式
更新時間：2017年05月12日 14:17:56 作者：夢想如歌！
這篇文章主要為大家詳細介紹了java實現(xiàn)簡單的webservice方式，具有一定的參考價值，感興趣的小伙伴們可以參考一下
本文實例為大家分享了java實現(xiàn)webservice方式的具體代碼，供大家參考，具體內(nèi)容如下
經(jīng)過測試 jdk1.6.10以下會出現(xiàn)bug 建議使用10以上版本
1、定義接口
package org.enson.chan;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
@WebService
@SOAPBinding(style=SOAPBinding.Style.RPC)
public interface IMyService {
public int add(int a , int b);
public int max(int a , int b);
}
2、實現(xiàn)接口
package org.enson.chan;
import javax.jws.WebService;
@WebService(endpointInterface="org.enson.chan.IMyService")
public class MyServiceImpl implements IMyService {
public int add(int a, int b) {
System.out.println(a+"+"+b+"="+(a+b));
return a+b;
}
public int max(int a, int b) {
System.out.println("a與b比較大小，取大值"+((a>b)?a:b));
return (a>b)?a:b;
}
}
3、定義服務(wù)
package org.enson.chan;
import javax.xml.ws.Endpoint;
public class MyServer {
public static void main(String[] args) {
String address = "http://localhost:8090/ns";
Endpoint.publish(address, new MyServiceImpl());
}
}
4、測試服務(wù)
package org.enson.chan;
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:8090/ns?wsdl");
QName sname = new QName("http://chan.enson.org/", "MyServiceImplService");
//創(chuàng)建服務(wù)
Service service = Service.create(url,sname);
//實現(xiàn)接口
IMyService ms = service.getPort(IMyService.class);
System.out.println(ms.add(12,33));
//以上服務(wù)有問題，依然依賴于IMyServie接口
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
5、TestSoap
