webservice实验一

webservice实验一,第1张

实验目的:安装jdk1.6_21以后的版本,利用JAX-WS API自己发布webservice并调用,以及用wsimport生成webservice客户端代码调用一个免费的web服务(如webxml.com.cn上的获取手机归属地的服务)。

一、webservice原理了解

webservice是一种通用的跨语言跨平台的数据交互方式,之所以能够做到这一点,是因为它的底层实现机制是依赖于HTTP协议以及XML格式这些开发的标准。webservice使用SOAP(simple object access protocol)协议来传送请求和响应消息,使用WSDL(webservice description language)来描述发布的服务。其中,

1)SOAP=在HTTP的基础上+XML数据,按照规范,SOAP的组成有:

Envelope:必须,xml数据的根元素

Headers:可选

Body:必须,包含要执行的服务的方法和发送到服务器的数据

SOAP的请求(本质上认识POST方式的HTTP请求)类似于如下:

POST /WebServices/MobileCodeWS.asmx HTTP/1.1 Host: webservice.webxml.com.cn Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://WebXml.com.cn/getMobileCodeInfo" <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <getMobileCodeInfo xmlns="http://WebXml.com.cn/"> <mobileCode>18212124343</mobileCode> <userID>null</userID> </getMobileCodeInfo> </soap:Body> </soap:Envelope>

SOAP的响应信息类似如下:

HTTP/1.1 200 OK Content-Type: text/xml; charset=utf-8 Content-Length: 3223 <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <getMobileCodeInfoResponse xmlns="http://WebXml.com.cn/"> <getMobileCodeInfoResult>18212124343:上海 上海 上海移动全球通卡</getMobileCodeInfoResult> </getMobileCodeInfoResponse> </soap:Body> </soap:Envelope>

2)WSDL主要是给服务调用者看的,说明了服务的地址和端口,以及提供的方法和参数信息。由于WSDL规范,我们也可以使用JDK1.6以后提供的wsimport工具生长webservice调用的客户端代码,以简化webservice的调用。

WSDL的数据大概如下:

<?xml version="1.0" encoding="utf-8"?> <wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/"

其中,soap:address location=""说明了web服务所在的url地址,service name=""说明了web服务的实现类,operation name=""说明了实现类中公开的可以调用的方法。

二、发布一个简单的webservice并调用

1)发布webservice服务器端

package cn.itcast.webservices.test; import javax.jws.WebService; import javax.xml.ws.Endpoint; @WebService public class HelloService { /** * @param args */ public static void main(String[] args) { Endpoint.publish("http://192.168.152.128:6888/hello", new HelloService()); } public String sayHello(String name) { return name + ": hello!!!!"; } }

服务器端的代码比较简单,注解WebService把java类标记为实现webservice或者是将Java接口标记为webservice接口。Endpoint的publish方法,会将一个用@WebService注解的类绑定到一个特定地址上并发布为webservice。(publish方法执行的时候,会启动新的线程,在该线程上监听客户端的请求)

查看wsdl如下:

<?xml version="1.0" encoding="UTF-8"?><!-- Published by JAX-WS RI at http://jax-ws.dev.java.net. RI‘s version is JAX-WS RI 2.1.6 in JDK 6. --><!-- Generated by JAX-WS RI at http://jax-ws.dev.java.net. RI‘s version is JAX-WS RI 2.1.6 in JDK 6. --><definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://test.webservices.itcast.cn/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://test.webservices.itcast.cn/" name="HelloServiceService"> <types> <xsd:schema> <xsd:import namespace="http://test.webservices.itcast.cn/" schemaLocation="http://192.168.152.128:6888/hello?xsd=1"></xsd:import> </xsd:schema> </types> <message name="sayHello"> <part name="parameters" element="tns:sayHello"></part> </message> <message name="sayHelloResponse"> <part name="parameters" element="tns:sayHelloResponse"></part> </message> <portType name="HelloService"> <operation name="sayHello"> <input message="tns:sayHello"></input> <output message="tns:sayHelloResponse"></output> </operation> </portType> <binding name="HelloServicePortBinding" type="tns:HelloService"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"></soap:binding> <operation name="sayHello"> <soap:operation soapAction=""></soap:operation> <input> <soap:body use="literal"></soap:body> </input> <output> <soap:body use="literal"></soap:body> </output> </operation> </binding> <service name="HelloServiceService"> <port name="HelloServicePort" binding="tns:HelloServicePortBinding"> <soap:address location="http://192.168.152.128:6888/hello"></soap:address> </port> </service> </definitions>

 

2)生成客户端代码

wsimport -s . http://192.168.152.128:6888/hello?wsdl

生成代码目录如下:

3)测试调用

package cn.itcast.webservices.test; public class Client { public static void main(String[] args) { HelloServiceService hss = new HelloServiceService(); HelloService hs = hss.getHelloServicePort(); System.out.println(hs.sayHello("wsc")); } }

运行结果:

三、调用网络上的一个免费的web服务
