用xfire开发webservice总结

本实例是以简单的加减法（a+b和a-b）运算实现用xfire开发webservice服务端和客户端。 一、开发环境 运行环境： Tomcat 6.0.14,jdk 1.5 开发工具：Eclipse3.2 + MyEclipse 5.5 二、开发service(服务端) 开发之前请先到官方(http://xfire.codehaus.org/Download)下载xfire-distribution-1.2.6.zip并解压缩. 1.在MyEclipse 建立一个web工程，命名为：XFireWebService,在src目录下新建一个META-INF文件夹里包含xfire/service.xml，把xfire-1.2.6里lib所有jar和xfire-all-1.2.6.jar拷贝到工程lib里，工程具体信息如附件图 2.修改WebRoot/Web-INF/web.xml文件 <?xml version="1.0" encoding="UTF-8"?> <web-app> <welcome-file-list> ? <welcome-file>index.jsp</welcome-file> </welcome-file-list> ? <context-param> ???? <param-name>log4jConfigLocation</param-name> ???? <param-value>/WEB-INF/log4j.properties</param-value> ? </context-param> <servlet> ? <servlet-name>XFireServlet</servlet-name> ? <servlet-class> ?? org.codehaus.xfire.transport.http.XFireConfigurableServlet ? </servlet-class> ? <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> ???? <servlet-name>XFireServlet</servlet-name> ???? <url-pattern>/servlet/XFireServlet/*</url-pattern> </servlet-mapping> <servlet-mapping> ? <servlet-name>XFireServlet</servlet-name> ? <url-pattern>/services/*</url-pattern> </servlet-mapping> </web-app> 3.修改src/META-INF/xfire/services.xml文件 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://xfire.codehaus.org/config/1.0"> <service> ? <name>MathService</name> ? <namespace> ?? http://localhost:8080/XFireWebService/MathService ? </namespace> ? <serviceClass>com.test.ws.MathServiceImpl</serviceClass> </service> </beans> 4.写MathService接口类和MathServicImpl实现类 MathService接口类 package com.test.ws; public interface? MathService { public long add(int p1,int p2); public long minus(int p3,int p4); } MathServiceImpl实现类 package com.test.ws; public class MathServiceImpl implements? MathService{ public long add(int p1,int p2) { System.out.println(p1 + p2); ???? return p1 + p2; } public long minus(int p3,int p4) { System.out.println(p3 - p4); return p3 - p4; } } 5.MyEclipse会自动编译src文件，请到MyEclipse的workspace里找到刚才建的XFireWebService工程，打开工程并copy WebRoot文件夹到%TOMCAT_HOME%/webapps里并把WebRoot改名为xfire，参照图如附件： 三、开发client(客户端) 开发client有几种模式 1． 纯POJO模式 需要service端提供MathService接口类 package com.test.client; import java.net.MalformedURLException; import org.codehaus.xfire.XFire; import org.codehaus.xfire.XFireFactory; import org.codehaus.xfire.client.XFireProxyFactory; import org.codehaus.xfire.service.Service; import org.codehaus.xfire.service.binding.ObjectServiceFactory; import com.test.ws.MathService; public class CallXfireWebService_POJO { /** * @param args */ public static void main(String[] args) { Service serviceModel = new ObjectServiceFactory().create(MathService.class); XFire xfire = XFireFactory.newInstance().getXFire();? XFireProxyFactory factory = new XFireProxyFactory(xfire); String serviceUrl = "http://localhost:8080/xfire/services/MathService"; int p1 = 115; int p2 = 4; int p3 = 9; int p4 = 240; MathService client = null; try { client = (MathService) factory.create(serviceModel,serviceUrl); } catch (MalformedURLException e) { System.out.println( "Client call webservice has exception: " + e.toString()); } int result1 = (int) client.add(p1,p2); int result2 = (int) client.minus(p3,p4); System.out.println(result1); System.out.println(result2); } } 2． JSR181模式 Server端开发组需要向Client提供MathService的实现类MathServiceImpl，而不止于接口，有点危险,不提倡用这个模式。暂不研究。 3． SpringSide 暂空着，下轮用到再详解。 4． 动态模式 动态模式不需要服务端的class,但在性能上有所欠佳。 package com.test.client; import java.net.MalformedURLException; import java.net.URL; import org.codehaus.xfire.client.Client; public class DynamicXfireWebService { /** * @param args */ public static void main(String[] args) { Client client = null; try { client = new Client(new URL("http://localhost:8080/xfire/services/MathService?wsdl")); Object[] result1 = client.invoke("add",new Object[] {1,2}); Object[] result2 = client.invoke("minus",2}); System.out.println(result1[0]); System.out.println(result2[1]); } catch (MalformedURLException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } } } 5． 根据WSDL生成Client Stub 创建client文件夹里含build.xml文件，内容如下 <?xml version="1.0"?> <project default="genfiles" basedir="."> ??? <property name="lib" value="WebRoot/WEB-INF/lib" /> ??? <path id="myclasspath"> ??????? <fileset dir="${lib}"> ??????????? <include name="*.jar" /> ??????? </fileset> ??????? <pathelement location="${genfiles}" /> ??? </path> ??? <property name="code_path" value="src" /> ??? <property name="wsdl_path" value="http://localhost:8080/xfire/MathService?wsdl" /> ??? <property name="code_package" value="com.playphone.ws.client" /> ??? <target name="genfiles" description="Generate the files"> ??????? <taskdef name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask" classpathref="myclasspath" /> ??????? <wsgen outputDirectory="${code_path}" wsdl="${wsdl_path}" package="${code_package}" binding="xmlbeans" overwrite="true" /> ??? </target> </project> 用ms dos打开至client文件夹，执行ant. 在所生成的client工程里写一个含math方法的ClientTest类 四、启动Tomcat,测试 运行客户端程序即可看到结果。
