webservice方式如何在java项目中实现？很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
具体内容如下
1、定义接口
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、实现接口
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与b比较大小，取大值"+((a>b)?a:b));
return (a>b)?a:b;
}
}3、定义服务
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、测试服务
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");
//创建服务
Service service = Service.create(url,sname);
//实现接口
IMyService ms = service.getPort(IMyService.class);
System.out.println(ms.add(12,33));
//以上服务有问题，依然依赖于IMyServie接口
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}5、TestSoap
