前言:
XFire是新一代WebService框架,同时也支持与Spring集成,帮助我们方便快速地在Spring框架中开发WebService应用。
本节主要介绍XFire+Spring集成的2种常用的方法来实现简单的WebService应用
1、使用XFire的XFireSpringServlet和ServiceBean
2、使用Spring的DispatcherServlet与XFire的XFireExporter
准备工作:
XFire官方网站下载地址:http://xfire.codehaus.org/Download
开发环境:
Window7 + Eclipse3.3 + Tomcat6 + JDK-1.6
XFire服务端和客户端工程预览图:
First-使用XFire的XFireSpringServlet和ServiceBean
一、Server-服务端实现步骤: 1.创建service接口->2.创建Service接口的实现类->3.web.xml配置(XFireSpringServlet)->4.配置ServiceBean->5.服务发布
1、创建service接口
package webjar.foo;
import common.MyPojo; public interface MyDispatcherServletXFire
{
String divide(int dividend, int divisor); MyPojo getMyPojo(MyPojo pojo);
}
2、创建Service接口的实现类
package webjar.foo;
import common.MyPojo; // org.springframework.web.servlet.DispatcherServlet与org.codehaus.xfire.spring.remoting.XFireExporter结合实现XFire
public class MyDispatcherServletXFireImpl implements MyDispatcherServletXFire
{
@Override
public String divide(int dividend, int divisor)
{
return dividend + " ÷ " + divisor + " = " + (dividend / divisor);
} @Override
public MyPojo getMyPojo(MyPojo pojo)
{
System.out.println("Hi, The client's pojo is :" + System.getProperty("line.separator") + pojo); pojo.setName("DispatcherServlet and XFireExporter to publish xfire services");
pojo.setArray(new String[] { "Hi, Welcome to MyDispatcherServletXFire !" });
return pojo;
}
}
3、在web.xml文件中进行XFire拦截配置(XFireSpringServlet)
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- Spring加载的配置文件-->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 可以再这里加入xfire.xml也可以在applicationContext.xml中引入 -->
<param-value>
classpath:org/codehaus/xfire/spring/xfire.xml
classpath:context-webservice.xml
</param-value>
</context-param> <!-- Xfire Servlet -->
<servlet>
<servlet-name>XFireServlet</servlet-name>
<display-name>XFire Servlet</display-name>
<servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>XFireServlet</servlet-name>
<url-pattern>/remoting/*</url-pattern>
</servlet-mapping> <welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
4、新增context-webservice.xml文件,里面进行WebService服务的发布的基本配置(ServiceBean)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans> <!-- Spring和XFire实现方法一 -->
<!-- org.codehaus.xfire.spring.XFireSpringServlet与org.codehaus.xfire.spring.ServiceBean结合实现XFire --> <!-- Service实现类-->
<bean id="myXFireSpringServlet" class="xfirejar.foo.MyXFireSpringServletImpl" /> <!-- 这里的name属性并不是调用时的Service名字;调用时要用类名,而不能直接使用myXFireService -->
<bean name="myXFireService"
class="org.codehaus.xfire.spring.ServiceBean">
<!-- Service实现类 -->
<property name="serviceBean" ref="myXFireSpringServlet" />
<!-- Service接口 -->
<property name="serviceClass" value="xfirejar.foo.MyXFireSpringServlet" />
<property name="inHandlers">
<list>
<ref bean="addressingHandler" />
</list>
</property>
</bean> <bean id="addressingHandler" class="org.codehaus.xfire.addressing.AddressingInHandler" />
</beans>
5、验证服务发布状态
启动tomcat正常,因为本人的web工程名称为XFireFoo,因此在Browser地址输入http://ip:port/XFireFoo/remoting/MyXFireSpringServlet?wsdl,
如果显示效果和下面截图信息一致,即说明webservice服务端搭建成功!
二、Client-客户端实现步骤:
A、客户端与WebService服务端在同一应用
1、测试桩示例代码
package xfirejar.foo;
import java.net.MalformedURLException;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import common.MyPojo; public class XFireJarFoo
{
public static void main(String[] args) throws MalformedURLException
{
// 调用时要用类名(接口名称),而不能直接使用myXFireService
String serviceURL = "http://localhost:8080/XFireFoo/remoting/MyXFireSpringServlet";
Service serviceModel = new ObjectServiceFactory().create(MyXFireSpringServlet.class, null);
XFireProxyFactory serviceFactory = new XFireProxyFactory(); MyXFireSpringServlet myFire = (MyXFireSpringServlet) serviceFactory.create(serviceModel, serviceURL);
System.out.println(myFire.divide(9, 3)); MyPojo pojo = new MyPojo();
pojo.setArray(new String[] { "remoting" });
pojo.setName("XFireJarFoo"); System.out.println(myFire.getMyPojo(pojo));
}
}
PS:也可以使用XFire中的XFireClientFactoryBean来实现调用,可参见[转]:http://blog.csdn.net/wlbing0625/article/details/7744699
2、测试结果
9 ÷ 3 = 3
MyPojo{name = XFireSpringServlet and ServiceBean to publish xfire services array = [Hi, Welcome to MyXFireSpringServlet !]}
B、客户端与WebService服务端在不同应用
re: 通过访问http://ip:port/XFireFoo/remoting/MyXFireSpringServlet?wsdl地址我们可以获取到wsdl文件,
因此直接“使用eclipse自带WEB service client指定wsdl文件,从而反向生成java代码方式”进行webservice服务调用。
具体实现步骤可参见本人已发布的AXIS最佳实践章节中“客户端的开发”,So easy !
Second-使用Spring的DispatcherServlet与XFire的XFireExporter
一、Server-服务端实现步骤: 1.创建service接口->2.创建Service接口的实现类->3.web.xml配置(DispatcherServlet)->4.配置XFireExporter->5.服务发布
1、创建service接口
package webjar.foo; import common.MyPojo; public interface MyDispatcherServletXFire
{
String divide(int dividend, int divisor); MyPojo getMyPojo(MyPojo pojo);
}
2、创建Service接口的实现类
package webjar.foo; import common.MyPojo; // org.springframework.web.servlet.DispatcherServlet与org.codehaus.xfire.spring.remoting.XFireExporter结合实现XFire
public class MyDispatcherServletXFireImpl implements MyDispatcherServletXFire
{
@Override
public String divide(int dividend, int divisor)
{
return dividend + " ÷ " + divisor + " = " + (dividend / divisor);
} @Override
public MyPojo getMyPojo(MyPojo pojo)
{
System.out.println("Hi, The client's pojo is :" + System.getProperty("line.separator") + pojo); pojo.setName("DispatcherServlet and XFireExporter to publish xfire services");
pojo.setArray(new String[] { "Hi, Welcome to MyDispatcherServletXFire !" });
return pojo;
}
}
3、在web.xml文件中进行DispatcherServlet拦截配置(DispatcherServlet)
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- Spring加载的配置文件,主要通过ContextLoader中的CONFIG_LOCATION_PARAM = "contextConfigLocation" -->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 可以再这里加入xfire.xml也可以在applicationContext.xml中引入 -->
<param-value>
classpath:org/codehaus/xfire/spring/xfire.xml
classpath:context-webservice.xml
</param-value>
</context-param> <!-- Spring framework -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- 注意因为servlet-name为myxfire,固xfire配置文件名应该是myxfire-servlet.xml -->
<servlet>
<servlet-name>xfire</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xfire</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping> <welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
4、新增xfire-servlet.xml文件,里面进行WebService服务的发布的基本配置(XFireExporter)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans> <!-- basic configuration -->
<!-- 若是web.xml已经配置了org/codehaus/xfire/spring/xfire.xml,这里就不需要配置了 -->
<!-- <import resource="classpath:org/codehaus/xfire/spring/xfire.xml" /> --> <!-- Service实现类-->
<bean id="myImpl" class="webjar.foo.MyDispatcherServletXFireImpl" /> <!-- XFire发布服务核心处理类的配置 -->
<bean name="/IWebJarService" class="org.codehaus.xfire.spring.remoting.XFireExporter">
<property name="serviceFactory" ref="xfire.serviceFactory" />
<!-- Service实现类 -->
<property name="serviceBean" ref="myImpl" />
<!-- Service接口 -->
<property name="serviceClass" value="webjar.foo.MyDispatcherServletXFire" />
</bean>
</beans>
5、验证服务发布状态
启动tomcat正常,因为本人的web工程名称为XFireFoo,因此在Browser地址输入http://ip:port/XFireFoo/services/IWebJarService?wsdl,
如果显示效果和下面截图信息一致,即说明webservice服务端搭建成功!
二、Client-客户端实现步骤:
A、客户端与WebService服务端在同一应用
1、本地客户端测试桩
package webjar.foo;
import java.net.MalformedURLException;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import common.MyPojo; public class WebJarFoo
{
public static void main(String[] args) throws MalformedURLException
{
// 客户端访问时使用xfire-servlet.xml中的XFireExporter配置的name属性(IWebJarService)进行调用
String serviceURL = "http://localhost:8080/XFireFoo/services/IWebJarService";
Service serviceModel = new ObjectServiceFactory().create(MyDispatcherServletXFire.class, null);
XFireProxyFactory serviceFactory = new XFireProxyFactory(); MyDispatcherServletXFire myFire = (MyDispatcherServletXFire) serviceFactory.create(serviceModel, serviceURL);
System.out.println(myFire.divide(9, 3)); MyPojo pojo = new MyPojo();
pojo.setArray(new String[] { "services" });
pojo.setName("WebJarFoo"); System.out.println(myFire.getMyPojo(pojo));
}
}
2、测试结果
9 ÷ 3 = 3
MyPojo{name = DispatcherServlet and XFireExporter to publish xfire services array = [Hi, Welcome to MyDispatcherServletXFire !]}
B、客户端与WebService服务端在不同应用
re: 通过访问http://ip:port/XFireFoo/services/IWebJarService?wsdl地址我们可以获取到wsdl文件,
因此直接“使用eclipse自带WEB service client指定wsdl文件,从而反向生成java代码方式”进行webservice服务调用。
