在jboss启动时加载class方法(定时操作)

类别:Java 点击:0 评论:0 推荐:

一.在jboss启动时加载class方法

A. 编写class,要import org.jboss.varia.scheduler.Schedulable包,此包在%JBOSS_DISC%\server\all\lib目录下,同时要把编译好的class(压成包)放在%JBOSS_DISC%\server\all\lib目录下,以便能加载。

B.修改%JBOSS_DISC%/server/all/conf/jboss-service.xml文件

 

添加以下相似文字:

<!--============================================================ -->

<!-- Scheduler Initialization 定时操作                                                                      -->

<!--============================================================ -->

  <mbean code="org.jboss.varia.scheduler.Scheduler"

name="jboss. piosan.util:service=Scheduler">

<attribute name="StartAtStartup">true</attribute>

<attribute name="SchedulableClass">com.piosan.util.PiosanTimer</attribute>

<attribute name="SchedulableArguments">TheName,123456789</attribute>

<attribute name="SchedulableArgumentTypes">java.lang.String,long</attribute>

<attribute name="InitialStartDate">NOW</attribute>

<attribute name="SchedulePeriod">1000</attribute>

<attribute name="InitialRepetitions">-1</attribute>

   </mbean>

<!—name为任意但唯一,com.piosan.util.PiosanTimer为class名 -->

<!—SchedulableArguments的值为传递参数,这里为两个参数,theName为String型,123456789为long型,在SchedulableArgumentTypes中体现了 -->

<!—SchedulePeriod 的值为每隔1秒操作一次 -->

 

C. 附上PiosanTimer.java源代码例子

package com.util;

import org.jboss.varia.scheduler.*;

public class PiosanTimer implements Schedulable {

  private String name;

  private long value;

 

  public PiosanTimer(String name,long value)

  {

    this.name = name;

    this.value = value;

    System.out.println("name="+name+"  value="+value);

    

  }

 

  /**

  会自动执行此函数,

  */

public void perform(Date now,long remainingRepetitions)

  {

    System.out.println("perform,now:"+now+

    ",remainingRepetitions: "+remainingRepetitions+

    ",name: "+name+ ",value: "+value);

  }

}
