springboot执行定时任务timer和Schedule

2022-01-15 20:32:03  阅读：181  来源： 互联网

标签：ci SET springboot Schedule utf8 CHARACTER timer COLLATE NULL


方式一：

1.main方法上加注解

@EnableScheduling

2.写一个执行方法类

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

/**
 *    定时任务
 *    1. 在main方法加注解： @EnableScheduling
 *    2. 将这个类交给spring管理
 */
@Component
public class ScheduleDemo02 {

    @Scheduled(fixedRate = 5000L)
    public void test02() {
        System.out.println("schedule任务02");
    }

    @Scheduled(cron = "0/4 * * * * *")
    public void test03() {
        System.out.println("schedule任务03");
    }
}

 

方式二：

1、写一个类包含一个静态方法，并用timer执行定时任务

import java.util.Timer;
import java.util.TimerTask;

/**
 *    定时任务
 *      需要要main方法中调用这个方法
 */
public class Scheduledemo {
    public static void test01() {
        final Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                System.out.println("Timer 定时任务进行中... ");
            }
        },10,10000);
    }
}

2、在项目启动时，于main方法调用上方法

Scheduledemo.test01();

 

方式三：

1、quartz 定时任务，pom

<!--     定时任务        -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>

2、配置

spring:
  quartz:
    #相关属性配置
    properties:
      org:
        quartz:
          scheduler:
            instanceName: clusteredScheduler
            instanceId: AUTO
          jobStore:
            class: org.quartz.impl.jdbcjobstore.JobStoreTX
            driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
            tablePrefix: QRTZ_
            isClustered: true
            clusterCheckinInterval: 10000
            useProperties: false
          threadPool:
            class: org.quartz.simpl.SimpleThreadPool
            threadCount: 10
            threadPriority: 5
            threadsInheritContextClassLoaderOfInitializingThread: true
    #数据库方式
    job-store-type: jdbc
      #初始化表结构
      #jdbc:
    #initialize-schema: never
        #覆盖任务
    overwrite-existing-jobs: true
    #启动延迟
    startup-delay: 60s

3、配置类

import org.quartz.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**
 *     quartz 定时任务
 *      多实例执行定时任务时，只有一个去执行
 *     1. pom文件导包
 *     2. 配置属性
 *     3. 建表
 *     4. ScheduleConfig配置类
 *       本实例采用内部类来建的，方便管理，如果任务较多，可以建一般的类
 */
@Configuration
public class ScheduleConfig {

    class ABCJob extends QuartzJobBean {
        @Override
        protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
            // 运行任务
//            System.out.println(" 打印aaa ");
        }
    }

    @Bean(name = "ABCJobDetail")
    public JobDetail ABCJobDetail() {
        return JobBuilder.newJob(ABCJob.class).withIdentity("TheABCJob").storeDurably().build();
    }

    @Bean(name = "ABCJobTrigger")
    public Trigger ABCJobTrigger() {
        return TriggerBuilder.newTrigger()
                .forJob(ABCJobDetail())
                .withIdentity("ABCJobTrigger")
                .withSchedule(CronScheduleBuilder.cronSchedule(" 0/10 * * * * ?  "))
                .build();
    }
}

4、建表
