XFire创建WebService服务端和客户端
感谢这篇博客http://clq9761.iteye.com/blog/1261963的分享。
可能是环境搭建的原因,按照资料有些地方没有成功,于是自己改了一部分,写了下面的demo
1、服务端
1.1、新建web工程,复制需要的jar包到lib文件夹
1.2、web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>XFireTest</display-name> <servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class> org.codehaus.xfire.transport.http.XFireConfigurableServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> </web-app>
1.3、程序结构
1.3.1、写service接口
package service; import entity.User; public interface IHelloWorld { public String getHello(); public User getUser(User user); }
1.3.2、写实现类
package service; import entity.User; public class HelloWorld implements IHelloWorld { public String getHello() { return "Hello"; } public User getUser(User user) { User helloUser = new User(); helloUser.setName("hello," + user.getName()); return helloUser; } }
1.3.3、接口中用到了User对象的代码如下
package entity; public class User { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } }
1.3.4、写services.xml
services.xml的路径:src/META-INF/xfire/
<?xml version="1.0" encoding="UTF-8"?> <beans> <service xmlns="http://xfire.codehaus.org/config/1.0"> <!-- 服务名称,客户端调用时需要这个 --> <name>HelloWorld</name> <!-- 一般是网址,意义不大 --> <namespace>http://www.hello.com</namespace> <!-- 接口类 --> <serviceClass>service.IHelloWorld</serviceClass> <!-- 实现类 --> <implementationClass>service.HelloWorld</implementationClass> </service> </beans>
服务端程序完成。
1.4、测试服务端
将项目部署到tomcat中,并启动tomcat
在浏览器中输入:
http://localhost:8080/XFireTest/services/HelloWorld?wsdl
看到如下即服务端部署成功
2、写客户端
2.1、客户端和服务端在同一项目中;或者客户端有服务端的接口和实体类,例如:IHelloWorld.java、User.java
路径:/XFireTest/src/client/ClientTest.java
package client; import java.net.MalformedURLException; 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 service.IHelloWorld; import entity.User; public class ClientTest { public static void main(String[] args) throws MalformedURLException { Service service = new ObjectServiceFactory().create(IHelloWorld.class); XFireProxyFactory factory = new XFireProxyFactory(XFireFactory.newInstance().getXFire()); String url = "http://localhost:8080/XFireTest/services/HelloWorld"; IHelloWorld helloWorld = (IHelloWorld)factory.create(service, url); //String String str = helloWorld.getHello(); System.out.println(str); //User User user = new User(); user.setName("张三"); String userName = helloWorld.getUser(user).getName(); System.out.println(userName); } }
运行结果:
Hello
hello,张三
2.2、客户端和服务端不在同一项目中,利用build.xml
2.2.1、新建一个web工程,XFireClientTest,复制需要的jar到lib,除了写服务端用到的jar,还有其他jar包
web.xml没有要添加的内容,就是简单的默认配置,例如
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>XFireClientTest</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
程序结构
2.2.2、写build.properties,路径:/XFireClientTest/src/build.properties
src.dir=E:/workspaceJEE/XFireClientTest/src lib.dir=E:/workspaceJEE/XFireClientTest/WebContent/WEB-INF/lib wsdl.dir=http://localhost:8080/XFireTest/services/HelloWorld?wsdl
2.2.3、写build.xml,路径:/XFireClientTest/src/build.xml
<?xml version="1.0" encoding="UTF-8"?> <project name="WebService" basedir="." default="gen-webservice"> <property file="build.properties"></property> <path id="project-classpath"> <fileset dir="${lib.dir}"> <include name="**/*.jar" /> </fileset> </path> <target name="gen-webservice"> <taskdef name="wsgen" classname="org.codehaus.xfire.gen.WsGenTask" classpathref="project-classpath" /> <wsgen outputDirectory="${src.dir}" wsdl="${wsdl.dir}" package="test.client" overwrite="true"/> </target> </project>
2.2.4、右击运行build.xml
自动生成了如下代码,这些代码就是写客户端要用到的:
2.2.5、写客户端程序
路径:/XFireClientTest/src/client/ClientTest.java
package client; import entity.ObjectFactory; import entity.User; import test.client.HelloWorldClient; import test.client.HelloWorldPortType; public class ClientTest { public static void main(String[] args) { HelloWorldClient service = new HelloWorldClient(); HelloWorldPortType portType = service.getHelloWorldHttpPort(); //String String hello = portType.getHello(); System.out.println(hello); //User ObjectFactory factory = new ObjectFactory(); User user = factory.createUser(); user.setName(factory.createUserName("李四")); String userName = portType.getUser(user).getName().getValue(); System.out.println(userName); } }
运行结果:
Hello
hello,李四
客户端程序完成。
2.3、使用axis写客户端访问XFire的WebService的服务端
不需要方法1中的接口类,也不需要用工具生成客户端代码。
2.3.1、新建一个工程XFireClientTest2,复制jar包到lib中
web.xml按照工程的内容默认即可。
因为没调通不传参数的写法,因此在服务端的接口和实现类中增加了一个方法getResult(String param),服务端其他代码不变。代码如下:
注意是服务端的代码,也就是前面写的XFireTest工程!路径:/XFireTest/src/service/IHelloWorld.java
package service; import entity.User; public interface IHelloWorld { public String getHello(); public User getUser(User user); public String getResult(String param); }
注意是服务端的代码,也就是前面写的XFireTest工程!路径:/XFireTest/src/service/HelloWorld.java
package service; import entity.User; public class HelloWorld implements IHelloWorld { public String getHello() { return "Hello"; } public User getUser(User user) { User helloUser = new User(); helloUser.setName("hello," + user.getName()); return helloUser; } public String getResult(String param) { return "hello," + param; } }
写客户端代码:
package client; import java.rmi.RemoteException; import javax.xml.namespace.QName; import javax.xml.rpc.ServiceException; import org.apache.axis.client.Call; import org.apache.axis.client.Service; public class ClientTest { public static void main(String[] args) { try { Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress("http://localhost:8080/XFireTest/services/HelloWorld"); call.setOperationName(new QName("http://www.hello.com", "getResult")); call.setTimeout(new Integer(6000000)); call.addParameter("arg0", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN); String result = (String) call.invoke(new Object[] {"time"}); System.out.println(result); } catch (ServiceException e) { e.printStackTrace(); } catch (RemoteException e) { e.printStackTrace(); } } }
运行结果:
hello,time
客户端完成。
