学习WebService进行中......
今天总结一下前段时间学习WebServices的经验和成果......hehe
.........首先进行服务器端的编码
环境MyEclipse(服务器端)+Eclipse(客户端)+tomcat+jdk1.6+xFire
1....................创建工程
MyEclipse中集成了Xfire框架，这样给我们省了不少麻烦hh
.......接口
package com.demo;
//Generated by MyEclipse
public interface IHelloService {
public String example(String username);
}.......实现类
package com.demo;
//Generated by MyEclipse
public class HelloServiceImpl implements IHelloService {
public String example(String username) {
return username+"我来了!";
}
}
（做了点小动作....别见怪）
2................大头戏来了，用户验证监听处理器代码（大多通用直接copy吧）
package com.client;
import org.codehaus.xfire.MessageContext;
import org.codehaus.xfire.handler.AbstractHandler;
import org.jdom.Element;
public class ClientAuthenticationHandler extends AbstractHandler {
private String username = null;
private String password = null;
public ClientAuthenticationHandler() {
}
public ClientAuthenticationHandler(String username,String password) {
this.username = username;
this.password = password;
}
public void setUsername(String username) {
this.username = username;
}
public void setPassword(String password) {
this.password = password;
}
public void invoke(MessageContext context) throws Exception {
//为SOAP Header构造验证信息
Element el = new Element("header");
context.getoutMessage().setHeader(el);
Element auth = new Element("AuthenticationToken");
Element username_el = new Element("Username");
username_el.addContent(username);
Element password_el = new Element("Password");
password_el.addContent(password);
auth.addContent(username_el);
auth.addContent(password_el);
el.addContent(auth);
}
}
3.....................服务端收尾，配置service.xml文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://xfire.codehaus.org/config/1.0"> <service> <name>HelloService</name> <serviceClass>com.demo.IHelloService</serviceClass> <implementationClass> com.demo.HelloServiceImpl </implementationClass> <!--注册监听处理器--> <inHandlers> <handler handlerClass="com.handler.AuthentificationHandler"></handler> </inHandlers> <style>wrapped</style> <use>literal</use> <scope>application</scope> </service> </beans>
4......................服务端完成了，大家看看我的文件结构吧
5............................先给大家点惊喜，服务端配置好了，启动一下tomcat把我们的webService服务发布一下，
在浏览器中输入URL http://localhost:8080/WebService/services/HelloService?wsdl 如果显示
这个xml页面的话，恭喜你，发布成功了。
6.......................下面来看一下客户端如何进行编写
首先需要把xfire的架包导入工程（放到lib文件夹下）
先看看我的文件夹结构
在这里我用了config.properties进行存放接口路径（有点大材小用）
7...........................首先需要编写的是接口文件IHelloService.java(可以直接拷贝服务器端的)
package com.imp;
public interface IHelloService {
public String example(String username);
}
8................................然后编写PropertiesConfig用来读取properties文件
package com.test; import java.io.FileInputStream; import java.util.Properties; public class PropertiesConfig { public static String site; public static String getsite() { Properties p = new Properties(); try { p.load(new FileInputStream("src/config.properties")); } catch (Exception e) { e.printstacktrace(); } site = p.getProperty("webservice_site"); return site; } }
9........................................下面是客户端身份验证代码ClientAuthenticationHandler.java
package com.client;
import org.codehaus.xfire.MessageContext;
import org.codehaus.xfire.handler.AbstractHandler;
import org.jdom.Element;
public class ClientAuthenticationHandler extends AbstractHandler {
private String username = null;
private String password = null;
public ClientAuthenticationHandler() {
}
public ClientAuthenticationHandler(String username,String password) {
this.username = username;
this.password = password;
}
public void setUsername(String username) {
this.username = username;
}
public void setPassword(String password) {
this.password = password;
}
public void invoke(MessageContext context) throws Exception {
//为SOAP Header构造验证信息
Element el = new Element("header");
context.getoutMessage().setHeader(el);
Element auth = new Element("AuthenticationToken");
Element username_el = new Element("Username");
username_el.addContent(username);
Element password_el = new Element("Password");
password_el.addContent(password);
auth.addContent(username_el);
auth.addContent(password_el);
el.addContent(auth);
}
}
10....................................最后来到进行我们的接口调用吧
package com.test; import java.lang.reflect.Proxy; import java.net.MalformedURLException; import org.codehaus.xfire.client.*; import org.codehaus.xfire.service.Service; import org.codehaus.xfire.service.binding.ObjectServiceFactory; import com.client.ClientAuthenticationHandler; import com.imp.IHelloService; public class ClientTest { /** * @param args * @throws MalformedURLException */ public static void main(String[] args) { try { // 获取properties中的配置URL地址 String serviceUrl = PropertiesConfig.getsite();// 新增 Service serviceModel = new ObjectServiceFactory().create( IHelloService.class,null,serviceUrl + "?wsdl",null); IHelloService service = (IHelloService) new XFireProxyFactory() .create(serviceModel,serviceUrl); XFireProxy proxy = (XFireProxy) Proxy.getInvocationHandler(service); Client client = proxy.getClient(); // 发送授权信息 client.addOutHandler(new ClientAuthenticationHandler("admin","admin")); // 输出调用web services方法的返回信息 System.out.println(service.example("admin")); } catch (MalformedURLException e) { e.printstacktrace(); } catch (IllegalArgumentException e) { e.printstacktrace(); } } }
好了，代码部分到此为止
如果你的服务器还没有停止，那么我们现在可以来测试了
运行客户端程序
11...........................................客户端显示
12.....................................服务器端显示
13................................今天又进步一点.....................................good good study,day day up .
