WebService简单实例

一、创建对外公布的接口

package webService;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;

@WebService
@SOAPBinding
public interface MyServiceInter {
@WebResult(name="addResult")
int add(@WebParam(name="a")int a,@WebParam(name="b")int b);

}

二、创建接口的实现类

package webService;

import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;

@WebService
@SOAPBinding
public class MyService implements MyServiceInter{
@Override
public int add(int a, int b) {
System.out.println("a+b="+(a+b));
return a+b;
}

}

三、创建服务器对外发布接口

package webService;
import javax.xml.ws.Endpoint;

public class Server {
public static void main(String[] args) {
String address = "http://localhost:8888/webService";
Endpoint.publish(address, new MyService());
System.out.println("publish success");
}

}

服务器必须全程启动状态才能进行下一步，启动后可开启浏览器访问地址：http://localhost:8888/webService?wsdl    显示如下：

<port name="MyServicePort" binding="tns:MyServicePortBinding">

<soap:address location="http://localhost:8888/webService"/>

</port>

</service>

</definitions>

四、创建一个空的客户端web项目

五、利用cmd命令生产客户端代码

wsimport -d "（客户端项目src路径:E:\tan\Java\Workspaces\TheClient\src）" -keep (接口调用url：http://localhost:8888/webService?wsdl)

六、创建客户端测试类测试

package webservice;

public class MyClient {
public static void main(String[] args) {
MyServiceService myServiceService = new MyServiceService();
MyService myServicePort = myServiceService.getMyServicePort();
System.out.println(myServicePort.add(44, 570));
}

}

客户端输出：614

服务的输出：a+b=614
