Spring 对象在运行时如何表示？

此功能将在Spring 4.2中提供

https://jira.spring.io/browse/SPR-12748（免责声明：我报告了此问题，并为解决该问题提供了代码）。

// Warning there may be more than one ScheduledTaskRegistrar in your// application context. If this is the case you can autowire a list of // ScheduledTaskRegistrar instead.@Autowired   private ScheduledTaskRegistrar scheduledTaskRegistrar; public List<Task> getScheduledTasks() {    List<Task> result = new ArrayList<Task>();    result.addAll(this.scheduledTaskRegistrar.getTriggerTaskList());    result.addAll(this.scheduledTaskRegistrar.getCronTaskList());    result.addAll(this.scheduledTaskRegistrar.getFixedRateTaskList());    result.addAll(this.scheduledTaskRegistrar.getFixedDelayTaskList());    return result;}// You can this inspect the tasks, // so for example a cron task can be inspected like this:public List<CronTask> getScheduledCronTasks() {    List<CronTask> cronTaskList = this.scheduledTaskRegistrar.getCronTaskList();    for (CronTask cronTask : cronTaskList) {        System.out.println(cronTask.getexpression);    }    return cronTaskList;}

如果您使用的是XML中定义的ScheduledMethodRunnable：

<task:scheduled method="run" cron="0 0 12 * * ?" ref="MyObject" />

您可以访问基础目标对象：

 ScheduledMethodRunnable scheduledMethodRunnable = (ScheduledMethodRunnable) task.getRunnable(); TargetClass target = (TargetClass) scheduledMethodRunnable.getTarget();
