webservice-demo

webservice开发步骤：

  服务端开发

—定义服务接口

—实现服务接口

—经过CXF、xfire、axis等框架对外发布服务

 客户端调用

—经过有效途径（双方沟通、UDDI查找等）获取到Webservice的信息

—经过wsdl生成客户端（或者服务提供方提供对应的接口jar包）

—调用服务

service接口：

package com.ws.jaxws.sayHello.service;

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

@WebService
//@SOAPBinding(style=Style.RPC)
public interface SayHelloService {
    public String sayHello(String name);
}

service接口的实现类：

package com.ws.jaxws.sayHello.service.impl;

import javax.jws.WebService;

import com.ws.jaxws.sayHello.service.SayHelloService;

@WebService(endpointInterface = "com.ws.jaxws.sayHello.service.SayHelloService", name = "sayHelloService", targetNamespace = "sayHello")

public class SayHelloServiceImpl implements SayHelloService {

    @Override
    public String sayHello(String name) {
        // TODO Auto-generated method stub
        if("".equals(name)||name==null){
            name="nobody";
        }
        return "hello "+name;
    }

}

客户端：

package com.ws.jaxws.sayHello.server;

import javax.xml.ws.Endpoint;

import com.ws.jaxws.sayHello.service.impl.SayHelloServiceImpl;

public class SayHelloServer {
    public static void main(String[] args) throws Throwable{
        Endpoint.publish("http://localhost:8888/sayHelloService", new SayHelloServiceImpl());
        System.out.println("SayHelloService is running....");
        Thread.sleep(5 * 60 * 1000);
        System.out.println("time out....");
        System.exit(0);
    }
}

运行客户端代码后在浏览器输入http://localhost:8888/sayHelloServoce?wsdl，便可生成wsdl代码，以下所示：

客户端调用：

package com.ws.jaxws.sayHello.client;

import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.namespace.QName;
import javax.xml.ws.Service;

import com.ws.jaxws.sayHello.service.SayHelloService;

public class SayHelloClient {
    public static void main(String[] args) throws MalformedURLException {
        String url="http://localhost:8888/sayHelloService?wsdl";
        Service service=Service.create(new url), new QName("sayHello","SayHelloServiceImplService")); //得到webservice的信息
        SayHelloService sayHelloService=service.getPort(SayHelloService.class);//return a proxy
        System.out.println(sayHelloService.sayHello(null));//调用服务
        System.out.println(sayHelloService.sayHello("zhangsan"));
    }
}

运行客户端代码，控制端输出： hello nobody hello zhangsan
