使用XFire开发WebService

使用XFire开发WebService，环境：Myeclipse5.0GA (eclipse3.2) XFIRE1.1 Tomcat 6.0.2 现在就开始:

1. 在Myeclipse中新建一个WEB Service PROJECT，如XFIRE2007。

2. 选中工程XFIRE2007,右键导入Myeclipse--Add Spring Capabilities....,所有均选择默认值。

3. 以上步骤完成后,修改src目录下的applicationContext.xml文件,内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
 <bean id="echoBean" class="cutelion.xfire.DIYEchoImpl" />
</beans>

4. 在src目录下新建log4j.properties,内容如下：

log4j.rootLogger=WARN, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

5. 修改WEB-INF目录下的web.xml文件,内容如下:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" 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>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>
   -->
 
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/classes/applicationContext.xml
        classpath:org/codehaus/xfire/spring/xfire.xml</param-value>
    </context-param>

    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>/WEB-INF/classes/log4j.properties</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <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>/*</url-pattern>
    </servlet-mapping>
</web-app>

 

6. 在WEB-INF目录下建立一个xfire-servlet.xml文件,内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
    <!-- START SNIPPET: xfire -->
    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="urlMap">
            <map>
                <entry key="/EchoService">
                    <ref bean="echo"/>
                </entry>
            </map>
        </property>
    </bean>
   
    <!-- Declare a parent bean with all properties common to both services -->
    <bean id="echo" class="org.codehaus.xfire.spring.remoting.XFireExporter">
        <property name="serviceFactory">
            <ref bean="xfire.serviceFactory"/>
        </property>
        <property name="xfire">
            <ref bean="xfire"/>
        </property>
        <property name="serviceBean">
            <ref bean="echoBean"/>
        </property>
        <property name="serviceClass">
            <value>cutelion.xfire.DIYEcho</value>
        </property>
    </bean>
    <!-- END SNIPPET: xfire -->
</beans>

7. 在src下面建立cutelion.xfire包，用于服务发布, 其中建立一个DIYEcho.java接口和DIYEchoImpl.java类实现。内容如下：
接口: DIYEcho.java

// START SNIPPET: echo
package cutelion.xfire;

public interface DIYEcho
{
    String DIYecho(String in);
}
// END SNIPPET: echo

接口实现: DIYEchoImpl.java

// START SNIPPET: echo
package cutelion.xfire;

import java.text.DateFormat;
import java.util.Date;
import java.util.GregorianCalendar;

/**
 * Provides a default implementation of the echo service interface.
 */
public class DIYEchoImpl implements DIYEcho
{
    public String DIYecho(String in)
    {  
     GregorianCalendar today = new GregorianCalendar();
     Date d = today.getTime();
     DateFormat df = DateFormat.getDateTimeInstance();
     String todaytostring = df.format(d);
        return todaytostring+" 輸入："+in;
    }
}
// END SNIPPET: echo

8. 到这里现在可以部署服务了, 工程右键Myeclipse-->Add and Move Project Deployment..... 到 Tomcat 下面。重启Tomcat。

9. 一切OK，Tomcat启动正常,没有错误。可以访问WSDL，在浏览器中输入：
http://127.0.0.1:8080/XFIRE2007/EchoService?wsdl出现一大堆的XML，表明服务EchoService发布成功.
在浏览器中输入：http://127.0.0.1:8080/XFIRE2007/EchoService 出现
Invalid SOAP request.  OK!

以上表明服务发布成功。以下为客户端的测试：

为了充分体现SPRING的IOC特性，现做以下测试。
10. 在src下建立一个applicationContext-client.xml 配置文件.内容如下：
 <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
 <bean id="Client_Params" class="cutelion.xfire.client.ClientParams">
  <property name="訪問地址">
   <value>http://localhost:8080/XFIRE2007/EchoService</value>
  </property>
  <property name="輸入字符串">
   <value>1234567890ABCDEFG XFIRE與SPRING集成成功! </value>
  </property>
 </bean>
</beans>

11. 在src下建立Package： cutelion.xfire.client，其中建立一个客户端参数的类ClientParams.java 和测试服务的类 TestDIYEcho.java 其内容如下所示:

ClientParams.java

package cutelion.xfire.client;

public class ClientParams {
 private String 輸入字符串;
    private String 訪問地址;
 public String get輸入字符串() {
  return 輸入字符串;
 }

 public void set輸入字符串(String 輸入字符串) {
  this.輸入字符串 = 輸入字符串;
 }

 public String get訪問地址() {
  return 訪問地址;
 }

 public void set訪問地址(String 訪問地址) {
  this.訪問地址 = 訪問地址;
 }
}

TestDIYEcho.java

package cutelion.xfire.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 org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import cutelion.xfire.DIYEcho;
import cutelion.xfire.client.ClientParams;
public class TestDIYEcho {
 public static void main(String args[]) {
  ApplicationContext ctx = new FileSystemXmlApplicationContext("src/applicationContext-client.xml");
  ClientParams cp=(ClientParams)ctx.getBean("Client_Params");
  String inputString=cp.get輸入字符串();
  Service srvcModel = new ObjectServiceFactory().create(DIYEcho.class);
  XFireProxyFactory factory = new XFireProxyFactory(XFireFactory
    .newInstance().getXFire());
  //String url = "http://localhost:8080/XFIRE2007/EchoService";
  String url = cp.get訪問地址();
  try {
   DIYEcho srvc = (DIYEcho) factory.create(srvcModel, url);
   System.out.print(srvc.DIYecho(inputString));
  } catch (MalformedURLException e) {
   e.printStackTrace();
  }
 }
}

12. 完成TestDIYEcho.java的编写后，直接进行测试( alt+shift+X  J )运行：
结果为：
2007-1-18 15:37:30 輸入：1234567890ABCDEFG XFIRE與SPRING集成成功
