我想定义一个作业，然后使用简单的计划多次触发它。
这项工作是这样定义的：
scheduler.addJob(JobBuilder.newJob(ExampleJob.class)
.storeDurably()
.requestRecovery()
.withDescription("Some nice description")
.withIdentity(JOB_NAME, GROUP_NAME)
.build(), false);
以这种方式安排调度（第二次调用失败）：
schedule(UUID.randomUUID(), Date.from(ZonedDateTime.now().plusSeconds(5).toInstant()));
schedule(UUID.randomUUID(), Date.from(ZonedDateTime.now().plusSeconds(10).toInstant()));
schedule方法以这种方式实现：
private void schedule(UUID userId, Date date) throws SchedulerException
{
logger.info("Scheduling job {} in group {} at {}", JOB_NAME, GROUP_NAME, date);
JobDetail job = scheduler.getJobDetail(JobKey.jobKey(JOB_NAME, GROUP_NAME));
TriggerKey triggerKey = TriggerKey.triggerKey(TRIGGER_NAME + "_" + userId, GROUP_NAME.toString());
Trigger trigger = newTrigger()
.forJob(job)
.withIdentity(triggerKey)
.usingJobData(new JobDataMap(Collections.singletonMap(ExampleJob.USER_ID_KEY, userId.toString())))
.startAt(date)
.withSchedule(simpleSchedule().withMisfireHandlingInstructionFireNow())
.build();
scheduler.scheduleJob(trigger);
}
如上所述，对schedule的第二次调用失败了。即使使用随机UUID构建触发器键，也会发生重复输入错误：

更糟糕的是：在此之后，Quartz数据与调度程序无法启动的级别不一致：

非常欢迎有关如何解决此问题的建议。 我们可以提供完整的重复版here on GitHub。
答案 0 :(得分：4)
事实证明，这是Liquibase架构定义中的一个问题。
主键是这样定义的：
- addPrimaryKey:
columnNames: SCHED_NAME
tableName: QRTZ_SIMPLE_TRIGGERS
constraintName: PK_QRTZ_SIMPLE_TRIGGERS
应该是这样的：
- addPrimaryKey:
columnNames: SCHED_NAME, TRIGGER_NAME, TRIGGER_GROUP
tableName: QRTZ_SIMPLE_TRIGGERS
constraintName: PK_QRTZ_SIMPLE_TRIGGERS
