如何动态的使用spring的调度,支持cron 表达式

spring scheduler

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.TaskScheduler;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;

@Configuration
public class SchedulerConfig implements SchedulingConfigurer {
  private static final Logger log = LoggerFactory.getLogger(SchedulerConfig.class);


  @Override
  public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {
    scheduledTaskRegistrar.setScheduler(threadPoolTaskScheduler() );
  }


  @Bean
  public ThreadPoolTaskScheduler threadPoolTaskScheduler() {
    ThreadPoolTaskScheduler threadPoolTaskScheduler = new ThreadPoolTaskScheduler();
    threadPoolTaskScheduler.setPoolSize(10);
    return threadPoolTaskScheduler;
  }
//

  @Bean
  public TaskScheduler poolScheduler() {
    ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
    scheduler.setThreadNamePrefix("poolScheduler");
    scheduler.setPoolSize(10);
    return scheduler;
  }

  //TODO 配置线程池
}
