webService开发笔记（二）

schema和http我们都了解的差不多了，下面我们就谈谈发布webservice和用jdk生成客户端代码以及使用Eclipse的监听；

1.启动webservice

这里我们用jdk自带的功能

helloWS.java

package com.atguigu.day01_ws.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;

/*
 * SEI: 
 */
@WebService
public interface HelloWS {

	@WebMethod
	public String sayHello(String name);
}

helloWSImpl.java

package com.atguigu.day01_ws.ws;

import javax.jws.WebService;

/*
 * SEI
 */
@WebService
public class HelloWSImpl implements HelloWS {

	@Override
	public String sayHello(String name) {
		System.out.println("server sayHello()"+name);
		return "goodNight " +name;
	}

}

这里@webService 和@WebMethod注解分别对应的是类和方法，这里简单的我们以及写好，下面写发布测试类

test.java

package com.atguigu.day01_ws.ws.server;

import javax.xml.ws.Endpoint;

import com.atguigu.day01_ws.ws.HelloWSImpl;

/*
 * 发布Web Service
 */
public class ServerTest {

	public static void main(String[] args) {

		String address = "http://localhost:8989/day01_ws/hellows";
		Endpoint.publish(address,new HelloWSImpl());
		System.out.println("发布webservice成功!");
	}
}

这时候启动，我们会发现以及启动成功，用网页打开

</definitions>

http://localhost:8989/day01_ws/hellows?wsdl地址查看如上
这是发布后的xml信息，分为五大结构，后面会介绍

2.用jdk的工具生成客户端代码

这就是jdk下bin文件夹下的工具，可以用它生成客户端代码

新建一个工程，运行cmd,进入dos命令下，cd ? ?(地址） ? ?地址是新建工程的src目录，也就是 生成客户端代码的地方，然后运行

wsimport ? -keep ? ? ? (wsdl地址） ? ? ? ? ? ?这里的地址可以网上免费的wsdl地址。也可以是你自己写的wsdl地址，运行后，刷新目录。

这里就是生成的代码，这里就需要我们写一个测试类来测试了

clientTest.java

<pre name="code" class="java">package com.atguigu.day01_ws.ws_server;
import com.atguigu.day01_ws.ws.HelloWSImpl;
import com.atguigu.day01_ws.ws.HelloWSImplService;

/**
 *调用webservice
 * @author yb
 *
 */
public class ClientTest {

	public static void main(String[] args) {
		HelloWSImplService factory = new HelloWSImplService();
		HelloWSImpl helloWS = factory.getHelloWSImplPort();
		System.out.println(helloWS);
		System.out.println(helloWS.getClass());
		String result = helloWS.sayHello("yb");
		System.out.println("client: "+result);
	}

}

运行后，

<pre name="code" class="java"><img src="http://img.blog.csdn.net/20140831190829617?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQveWliaW5nNTQ4/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="" />

这就表示发布成功了。

3.监听，这里我就不多讲了，我介绍下
