java - Spring 计划任务未触发

我正在自学 Spring，目前正在执行计划任务，以下代码不会触发计划任务。

我相信这与我设置 Spring 上下文的方式有关，但这只是一个猜测 - 我正在尝试学习 Spring，所以请原谅可笑的 while 循环。

应用程序.java:

package hello;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Application {

    public static void main(String[] args) throws Exception {
        AnnotationConfigApplicationContext rootContext =
                        new AnnotationConfigApplicationContext();

        rootContext.register(RootContextConfiguration.class);
        rootContext.refresh();

        while(rootContext != null) {
            try {
                Thread.sleep(2500);
            } catch(InterruptedException ex) {
                Thread.currentThread().interrupt();
            }

            System.out.println("Loop\n");
        }

        rootContext.close();
    }
}

RootContextConfiguration.java:

package hello;

import java.util.concurrent.Executor;

import org.springframework.context.annotation.AdviceMode;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.scheduling.TaskScheduler;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;

@Configuration
@EnableScheduling
@EnableAsync(
        mode = AdviceMode.PROXY, proxyTargetClass = false,
        order = Ordered.HIGHEST_PRECEDENCE
)
@ComponentScan(
        basePackages = "hello"
)
public class RootContextConfiguration implements
AsyncConfigurer, SchedulingConfigurer {
    @Bean
    public ThreadPoolTaskScheduler taskScheduler()
    {
        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        scheduler.setPoolSize(20);
        scheduler.setThreadNamePrefix("task-");
        scheduler.setAwaitTerminationSeconds(60);
        scheduler.setWaitForTasksToCompleteOnShutdown(true);
        return scheduler;
    }

    @Override
    public Executor getAsyncExecutor()
    {
        Executor executor = this.taskScheduler();
        return executor;
    }

    @Override
    public void configureTasks(ScheduledTaskRegistrar registrar)
    {
        TaskScheduler scheduler = this.taskScheduler();
        registrar.setTaskScheduler(scheduler);
    }
}

ScheduledTasks.java:

package hello;

import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;

@EnableScheduling
public class ScheduledTasks {

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

    @Scheduled(fixedRate = 5000)
    public void reportCurrentTime() {
        System.out.println("The time is now " + dateFormat.format(new Date()));
    }
}

需要明确的是， hibernate 2.5 秒并打印“循环”只是为了让应用程序运行以查看计划任务是否触发。

我正在寻找的是打印触发时间的计划任务。它不是。

在此先感谢您提供的任何帮助。

最佳答案

您没有 ScheduledTasks bean。使用 @Component(或其任何特化)注释您的类或在您的 @Bean 类中为其声明 @Configuration 方法。
@EnableScheduling 属于 @Configuration 类，而不是具有预定行为的类。您可以将其从 ScheduledTasks 中删除。

关于java - Spring 计划任务未触发，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/23301622/
