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:

bubuko.com,布布扣
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>
bubuko.com,布布扣

SOAP的响应信息类似如下:

bubuko.com,布布扣
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>
bubuko.com,布布扣

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:

bubuko.com,布布扣
<?xml version="1.0" encoding="utf-8"?>

    <wsdl:port name="MobileCodeWSSoap" binding="tns:MobileCodeWSSoap">
      <soap:address location="http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx" />
    </wsdl:port>
    <wsdl:port name="MobileCodeWSSoap12" binding="tns:MobileCodeWSSoap12">

      <http:address location="http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx" />
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>
View Code

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

bubuko.com,布布扣
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!!!!";
    }

}
bubuko.com,布布扣

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:

bubuko.com,布布扣
<?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>
bubuko.com,布布扣

 

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:

bubuko.com,布布扣

3)测试调用

bubuko.com,布布扣
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"));
    }
}
bubuko.com,布布扣

运行结果:

bubuko.com,布布扣

三、调用网络上的一个免费的web服务
