quartz触发器 JobDataMap

http://blog.youkuaiyun.com/a67474506/article/details/38317119

JobDataMap可以用来保存任何需要传递给任务实例的对象（这些对象要求是可序列化的）

作业类

public class ColorJob implements Job{
    private static final String FAVORITE_COLOR = "favorite color";
    public static final String EXECUTION_COUNT = "count";
    private int _counter = 1;
    private JobDataMap jobDataMap;

    public void execute(JobExecutionContext context)
            throws JobExecutionException {
        // TODO Auto-generated method stub
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy年MM月dd日 HH时mm分ss秒");
        JobKey jobKey=context.getJobDetail().getKey();
        
        this.jobDataMap=context.getJobDetail().getJobDataMap();
        String favoriteColor=jobDataMap.getString("color");
        int count=jobDataMap.getInt("count");
        System.out.println("ColorJob:在"+sdf.format(new Date())+"执行"+jobKey+"\n"
                +"color:"+favoriteColor+"\n"
                +"第"+count+"次执行\n"+"成员变量_counter是第"+this._counter+"次 执行");
        ++count;
        jobDataMap.put("count", count);
        System.out.println(count);
        this._counter+=1;
    }

}
