title: webService的一些记录

简介

webService是什么
(1) 服务端提供资源给客户端应用访问
(2) 跨语言，跨平台的应用间通信整合方案
为什么使用webservice
能解决跨语言，跨平台，远程调用
什么时候用webservice
(1)新旧系统
(2)不同公司之间的应用
(3)提供数据的应用
webService中的术语
(1) WSDL(web service definition language) - WSDL是webservice定义语言, 对应.wsdl文档, 一个webservice会对应一个唯一的wsdl文档, 定义了客户端与服务端发送请求和响应的数据格式和过程
(2)SOAP(simple object access protocal) - SOAP是"简单对象访问协议"是一种简单的、基于HTTP和XML的协议, 用于在WEB上交换结构化的数据 ; soap消息：请求消息和响应消息
(3)SEI(WebService EndPoint Interface) - SEI是web service的终端接口，就是WebService服务器端用来处理请求的接口
(4) CXF(Celtix + XFire) - 一个apache的用于开发webservice服务器端和客户端的框架。

接口定义

@WebService
public interface HelloWorld {

   public String say(String str);

}

实现类

@WebService(endpointInterface="com.itic.webservice.HelloWorld")
//@Component("helloWorld")
public class HelloWorldImpl implements HelloWorld {

	@Override
	public String say(String str) {
		return "Hello " + str;
	}

}

部署到Tomcat ，访问 http://localhost:7090/WS_CXF/webservice 或 http://localhost:7090/WS_CXF/webservice/helloWorld?wsdl

客户端

客户端代码编写，可以采用工具生成：

进入到要生成的目录，执行wsdl2java http://localhost:7090/WS_CXF/webservice/helloWorld?wsdl, 刷新工程
我们需要做的是编写client的调用
- 创建服务视图对象
- 从服务视图中获得PortType对象。
- 调用PortType的方法(可以实现远程通信)
- 接收方法的返回值(服务端响应的结果)。

public static void main(String[] args) {
		HelloWorld service = new HelloWorldImplService().getHelloWorldImplPort();
		System.out.println(service.say("wanglao"));
	}
