java实现简单的webservice方式

本文实例为大家分享了java实现webservice方式的具体代码，供大家参考，具体内容如下

经过测试 jdk1.6.10以下会出现bug 建议使用10以上版本

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
