代码:
treadpooltaskscheduler
这是任务启动和停止服务代码:
@Autowired
private ThreadPoolTaskScheduler threadPoolTaskScheduler;
private ScheduledFuture<?> future;
@Bean
public ThreadPoolTaskScheduler threadPoolTaskScheduler() {
threadPoolTask.setPoolSize(10);
return new ThreadPoolTaskScheduler();
}
当我运行应用程序并运行2个任务并且打印“未来”时,我发现“未来”是相同的
答案 0 :(得分:0)
我认为您只需要一个
Thread.sleep(10000)
答案 1 :(得分:0)
默认threadPoolSize =1。因此,您的任务在一个线程中运行。
您应使用setPoolSize
设置线程池大小。
答案 2 :(得分:0)
ThreadPoolTaskScheduler
不是Java提供的类。因此,我认为这是第三方课程还是您自己的课程。处理此问题的正确位置在您的代码中:
@Bean
public ThreadPoolTaskScheduler threadPoolTaskScheduler() {
return new ThreadPoolTaskScheduler();
}
如果类ThreadPoolTaskScheduler
的构造函数采用线程数量(应如此),只需在该位置指定它,或者如果存在单独的setter方法来设置线程数量,则不更改上面的代码以首先创建一个实例,然后设置线程数。就像这样:
@Bean
public ThreadPoolTaskScheduler threadPoolTaskScheduler() {
return new ThreadPoolTaskScheduler(10);
}
或
@Bean
public ThreadPoolTaskScheduler threadPoolTaskScheduler() {
ThreadPoolTaskScheduler threadPoolTaskScheduler = new ThreadPoolTaskScheduler();
threadPoolTaskScheduler.setThreads(10)
return threadPoolTaskScheduler;
}
答案 3 :(得分:0)
情况1:您的ThreadPoolTaskScheduler大小为1
情况2:您的任务执行时间太短
您可以提供更多代码吗?
