java - Quartz 调度程序 - 使用同一类的不同作业？

Question

quartz 示例通常这样做:

JobDetail job = newJob(PrintMessageJob.class)

如何创建一个在运行时定义参数的作业？像这样的事情会很好，但不允许:

JobDetail job = newJob( new PrintMessageJob("my message") );

谢谢

您必须执行以下操作。

JobDetail job = newJob(PrintMessageJob.class)
               .usingJobData("message", "my message")
               .build();

public class PrintMessageJob implements Job {

    public PrintMessageJob() {
    }

    public void execute(JobExecutionContext context) throws JobExecutionException
    {
        JobDataMap dataMap = context.getJobDetail().getJobDataMap();

        String message = dataMap.getString("message");
        ...
    }
}
