XFire创建WebService实例应用

XFire创建WebService实例应用



  XFire使得在JavaEE应用中发布Web服务变得轻而易举。和其他Web服务引擎相比，
  XFire的配置非常简单，可以非常容易地和Spring集成。

   一． 使用XFire发布WebService


   1. 创建service接口



Java代码 
package com.test.service;  
import com.test.service.bean.User;  
  
public interface IHelloService {  
    public String sayHello(String name);  
   public User  getUser(User user);  
    }  
} 
    package com.test.service;
    import com.test.service.bean.User;
   
    public interface IHelloService {
    public String sayHello(String name);
    public User  getUser(User user);
   }
   } 
2.创建Service接口的实现类

Java代码 
package com.test.service;  
import com.test.service.bean.User;  
public class HelloService implements IHelloService{   
    public String sayHello(String name){  
       return "Hello, "+name;  
    }  
    public User getUser(User user) {  
        User userNew = new User();  
        userNew.setId("new:"+user.getId());  
        userNew.setName("new:"+user.getName());  
        return userNew;  
    }  
} 
package com.test.service;
import com.test.service.bean.User;
public class HelloService implements IHelloService{
public String sayHello(String name){
return "Hello, "+name;
}
public User getUser(User user) {
User userNew = new User();
userNew.setId("new:"+user.getId());
userNew.setName("new:"+user.getName());
return userNew;
}
} 

Java代码 
package com.test.service.bean;  
public class User {       
    private String id;  
    private String name;      
    public String getId() {  
        return id;  
    }  
    public void setId(String id) {  
        this.id = id;  
    }  
    public String getName() {  
        return name;  
    }  
    public void setName(String name) {  
        this.name = name;  
    }  
} 

   package com.test.service.bean;
   public class User {  
   private String id;
   private String name;
   public String getId() {
   return id;
   }
   public void setId(String id) {
   this.id = id;
   }
   public String getName() {
   return name;
   }
   public void setName(String name) {
   this.name = name;
   }
   }

3.在web.xml文件中进行XFire拦截配置，可参照官网提供的sample。

Xml代码 
<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   
   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 
 
<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>/servlet/XFireServlet/*</url-pattern> 
</servlet-mapping> 
<servlet-mapping> 
    <servlet-name>XFireServlet</servlet-name> 
    <url-pattern>/services/*</url-pattern> 
</servlet-mapping> 
</web-app> 
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<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>/servlet/XFireServlet/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>XFireServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
</web-app> 4.在class目录下建立META-INF目录,如（META-INF>xifre->services.xml）,
    在services.xml文件中进行webservice服务的发布，可参照官网提供的sample。

Xml代码 
<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://xfire.codehaus.org/config/1.0"> 
<service> 
    <name>HelloService</name> 
    <serviceClass>com.test.service.IHelloService</serviceClass> 
    <implementationClass>com.test.service.HelloService</implementationClass> 
</service>      
</beans> 
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<name>HelloService</name>
<serviceClass>com.test.service.IHelloService</serviceClass>
<implementationClass>com.test.service.HelloService</implementationClass>
</service>
</beans>

5.将xfire的Jar包和相关依赖包拷到系统应用中，在Tomcat下部署应用。
   启动tomcat后访问服务（需在应用后加上/services,webservice才会进行拦截）：
   例：http://localhost:8080/ws2/services。(IE下有时无法显示列表，可用其它浏览器显示或指定接口名称）
   界面如下：  

点击后查看详细的wsdl文档，不同的浏览器下访问会有区别，展示效果不一致。


二．建立XFire客户端进行调用

1.本地客户端调用，与webservice服务在同一应用。

Java代码 
package com.test.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 com.test.service.IHelloService;  
import com.test.service.bean.User;  
 
public class ClientTest {  
    public static void main(String args[]) throws MalformedURLException {  
        Service service = new ObjectServiceFactory().create(IHelloService.class);  
        XFireProxyFactory factory = new XFireProxyFactory(XFireFactory  
                .newInstance().getXFire());  
        String url = "http://localhost:8080/ws2/services/HelloService";  
        IHelloService helloService = (IHelloService) factory.create(service,url);  
        System.out.println(helloService.sayHello("张三"));  
        User user = new User();  
        user.setName("张三");  
        System.out.println(helloService.getUser(user).getName());  
       }  
} 
package com.test.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 com.test.service.IHelloService;
import com.test.service.bean.User;

public class ClientTest {
public static void main(String args[]) throws MalformedURLException {
Service service = new ObjectServiceFactory().create(IHelloService.class);
XFireProxyFactory factory = new XFireProxyFactory(XFireFactory
.newInstance().getXFire());
String url = "http://localhost:8080/ws2/services/HelloService";
IHelloService helloService = (IHelloService) factory.create(service,url);
System.out.println(helloService.sayHello("张三"));
User user = new User();
user.setName("张三");
System.out.println(helloService.getUser(user).getName());
}
}
执行结果如下：

Java代码 
1.Hello, 张三  
2.new:张三 
Hello, 张三
new:张三

2. 利用XFire创建build.xml文件生成客户端代码调用webservice服务

 
2.1在src目录下创建build.properties文件，配置如下：

Java代码 
src.dir=${basedir}  
lib.dir=D:/myspace/ws2/WebRoot/WEB-INF/lib  
wsdl.dir=http\://localhost\:8080/ws2/services/HelloService?wsdl 
src.dir=${basedir}
lib.dir=D:/myspace/ws2/WebRoot/WEB-INF/lib
wsdl.dir=http\://localhost\:8080/ws2/services/HelloService?wsdl

2.2在src目录下创建build.xml文件，配置如下：

Xml代码 
<?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="stub.test.client" overwrite="true"/>          
    </target> 
</project> 
<?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="stub.test.client" overwrite="true"/>
</target>
</project>    

用ant构建生成代码，生成后的目录如下：

 
2.3编写客户端代码进行调用

Java代码 
package com.test.client;  
import stub.test.client.HelloServiceClient;  
import stub.test.client.HelloServicePortType;  
import com.test.service.bean.ObjectFactory;  
import com.test.service.bean.User;  
 
public class HelloServiceTest {  
 
   public static void main(String args[]){  
       HelloServiceClient service = new HelloServiceClient();        
        HelloServicePortType portType = service.getHelloServiceHttpPort();            
        System.out.println(portType.sayHello("张三"));  
          
        ObjectFactory factory = new ObjectFactory();          
        User user = factory.createUser();  
        user.setName(factory.createUserName("张三"));  
        System.out.println(portType.getUser(user).getName().getValue());  
    }  
} 
package com.test.client;
import stub.test.client.HelloServiceClient;
import stub.test.client.HelloServicePortType;
import com.test.service.bean.ObjectFactory;
import com.test.service.bean.User;

public class HelloServiceTest {

public static void main(String args[]){
HelloServiceClient service = new HelloServiceClient();
HelloServicePortType portType = service.getHelloServiceHttpPort();
System.out.println(portType.sayHello("张三"));

ObjectFactory factory = new ObjectFactory();
User user = factory.createUser();
user.setName(factory.createUserName("张三"));
System.out.println(portType.getUser(user).getName().getValue());
}
}
