java代码：

package com.malq;

import java.util.Date;

public class SayHelloJob {

  public void sayHello(){
           Date date = new Date();
        System.out.println(date +" ::::: ------this is SayHelloJob!");
  }
  
}

package com.malq;

import java.util.Date;
public class MyQuartzJobBean{

 public void sayHello(){
          Date date = new Date();
       System.out.println(date +" ::::: ------this is MyQuartzJobBean!");
 }
 
}
