spring boot @Scheduled 单线程的问题

package com.lxw.lxwDemo;

import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@EnableScheduling
@Component
public class TaskScheduleService {

    @Scheduled(cron = "0/1 * * * * ?")
    public void task01() {
        System.out.println("task01 测试");
    }

    @Scheduled(cron = "0/1 * * * * ?")
    public void task02() {
        System.out.println("task02 测试");
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

由于spring scheduled默认是所有定时任务都在一个线程中执行!!!!
task02卡住会导致所有定时任务全部卡死的现象。

解决办法：

添加配置

@Configuration
public class ScheduleConfig {

    @Bean
    public TaskScheduler taskScheduler() {
        ThreadPoolTaskScheduler taskScheduler = new ThreadPoolTaskScheduler();
        taskScheduler.setPoolSize(2);
        return taskScheduler;
    }
}

此时task02卡住，task01可以正常执行的.
