Spring Boot 配置Scheduler定时调度任务线程池

添加配置类 SchedulerConfig

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;

@Configuration
public class SchedulerConfig {

    // 配置任务线程池，用于定时调度
    @Bean
    public ThreadPoolTaskScheduler taskScheduler() {
        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        scheduler.setPoolSize(30); // 设置线程池大小为30
        scheduler.setThreadNamePrefix("my-task-scheduler-"); // 设置线程名称前缀
        return scheduler;
    }
}

添加测试类

import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.Scheduled;
import java.time.LocalTime;

@Slf4j
@Configuration
public class TestScheduled {

    @Scheduled(fixedDelay = 500)
    public void test() {
        log.info("thread: {} current time: {}", Thread.currentThread(), LocalTime.now());
    }
}

日志输出，线程名称正确，也切换过其他线程执行
