Spring邮件抽象层和Spring中的定时调度的整合(四)

3）              写类

package example;



import mail.*;



public class ExampleBusinessObject {



      // properties and collaborators

      IOrderManager ordermanager;

      ISenderMail simplesender;

      public void doIt() {

         try {

             //简单的邮件发信

             //simplesender.sendMail();

             //使用回调函数发信

             ordermanager.placeOrder(new Customer("[e-mail]",

                                    "姓", "名", "邮件中的内容"));

             System.out.println("O,发送Email成功了....");



       } catch (Exception e) {

           System.out.println(e.getMessage());

           // TODO: handle exception

       }

       

  

      }

    public ISenderMail getSimplesender() {

       return simplesender;

    }

    public void setSimplesender(ISenderMail simplesender) {

       this.simplesender = simplesender;

    }

    public IOrderManager getOrdermanager() {

       return ordermanager;

    }

    public void setOrdermanager(IOrderManager ordermanager) {

       this.ordermanager = ordermanager;

    }

}

package example;



import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

import org.springframework.scheduling.quartz.QuartzJobBean;



public class ExampleJob extends QuartzJobBean {



  private int timeout;



  /**

   * Setter called after the ExampleJob is instantiated

   * with the value from the JobDetailBean (5)

   */

  public void setTimeout(int timeout) {

    this.timeout = timeout;

  }



  protected void executeInternal(JobExecutionContext ctx) throws JobExecutionException {

    

      System.out.println("FOR TEST!!!");

    

      // do the actual work

  }

}

2. 使用JDK Timer支持类

       1).配置JDKTimer.xml

                            位置：WEB-INF/conf/JDKTimer.xml

    例：

<?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="checkEmail" class="example.CheckEmailAddresses">

    <property name="emailAddresses">

       <list>

           <value>[e-mail]</value>

           <value>[e-mail]</value>

           <value>[e-mail]</value>

       </list>

    </property>

</bean>



<bean id="scheduledTask"

    class="org.springframework.scheduling.timer.ScheduledTimerTask">

    <!-- wait 10 seconds before starting repeated execution -->

    <property name="delay" value="10000" />

    <!-- run every 50 seconds -->

    <property name="period" value="10000" />

    <property name="timerTask" ref="checkEmail" />

</bean>



<bean id="timerFactory" class="org.springframework.scheduling.timer.TimerFactoryBean">

    <property name="scheduledTimerTasks">

        <list>

            <!-- see the example above -->

            <ref bean="scheduledTask" />

        </list>

    </property>

</bean>

</beans>

   2). 配置web.xml



       <context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>

            <!--WEB-INF/dataAccessContext.xml,-->

            WEB-INF/conf/applicationContext.xml,

            WEB-INF/conf/MailSender.xml，

WEB-INF/conf/JDKTimer.xml，

           WEB-INF/conf/QuartzTimer.xml

        </param-value>

    </context-param>



3).书写类  CheckEmailAddresses.java

package example;



import java.util.List;

import java.util.TimerTask;



public class CheckEmailAddresses extends TimerTask {

      private List emailAddresses;

      public void setEmailAddresses(List emailAddresses) {

        this.emailAddresses = emailAddresses;

      }

      public void run() {

        System.out.println("FOR TEST JDKTIMER");

      }

}

OK，所有的工作就做完了，配置了多种邮件抽象和定时调度，可以帮助理解其中几种配置在项目中的需求。

按上述配置好后，就可以运行TOMCAT了，不过请注意：

             在配置项目的时候要在CLASSPATH中加载额外的几个JAR包，这是类文件和配置文件所必须用到的：

                            Activation.jar

                            Javamail.jar

                            Quart.jar

                            Commons-collection-3.2.jar
