如何在 Quartz JDBC Store 中删除作业? [英] How to remove job in Quartz JDBC Store?

问题描述

我写这个方法是为了从 Quartz JDBC 中删除一个作业

I wrote this method to remove a job from Quartz JDBC

public boolean removeJob(String jobName) {
    try {
        JobKey jobKey = JobKey.jobKey(jobName);  
        try {    
            Scheduler sched = schedulerFactoryBean.getScheduler();  
            logger.info("RESULT: " + sched.deleteJob(jobKey)); 
        } catch (Exception e) {    
            throw new RuntimeException(e);    
        }    
        return true; 
    } catch (Exception ex) {
        logger.error(ex.getMessage());
        return false; 
    } 
} 

deleteJob 总是返回 false.因此，该作业不会从 mysql 的 JDBC 表中删除.我究竟做错了什么.我只想从调度程序中完全删除此作业

deleteJob is always returning false. So the job is not getting removed from the JDBC tables in mysql. What am I doing wrong. I only want to completely remove this job from the scheduler

推荐答案

您是否在创建作业时定义了作业组?然后你可能需要调用jobKey(jobName, group).您还可以使用 scheduler.checkExists(jobKey) 方法检查作业是否存在，这将有助于调试.

Have you defined a job group during job creation? Then you may need to call jobKey(jobName, group). You can also check if job exists with scheduler.checkExists(jobKey) method which will be good for debugging.

JobKey jobKey = jobKey(jobName, group);
if (scheduler.checkExists(jobKey)) {
    logger.info("job found with key: {}", jobKey); 
    scheduler.deleteJob(jobKey);
}
