bootstrap的quartz定时任务简单使用

（1）导入quartz

 <!--quartz定时调度依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>

 （2）设置定时任务的执行

package com.example.demo.config;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

import java.text.SimpleDateFormat;
import java.util.Date;
//设置定制任务的执行
class QuartzJob1 extends QuartzJobBean {
    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println("QuartzJob1----" + sdf.format(new Date()));
    }
}

 （3）设置配置文件

package com.example.demo.config;

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

@Configuration
public class QuartzConfig {
    @Bean
    public JobDetail jobDetail1(){
        return JobBuilder.newJob(QuartzJob1.class).storeDurably().build();
    }

    @Bean
    public Trigger trigger1(){
        SimpleScheduleBuilder scheduleBuilder = SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(1) //每一秒执行一次
                .repeatForever(); //永久重复，一直执行下去
        return TriggerBuilder.newTrigger()
                .forJob(jobDetail1())
                .withSchedule(scheduleBuilder)
                .build();
    }
}

 也可以使用内部类

@Bean
public JobDetail jobDetail2(){
    QuartzJobBean quartzJob2 = new QuartzJobBean() {
        @Override
        protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
            SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            System.out.println("内部类quartzJob2----" + sdf.format(new Date()));
        }
    };
    return JobBuilder.newJob(quartzJob2.getClass()).storeDurably().build();
}

@Bean
public Trigger trigger2(){
    //JobDetail的bean注入不能省略
    //JobDetail jobDetail3 = JobBuilder.newJob(QuartzJob2.class).storeDurably().build();
    SimpleScheduleBuilder scheduleBuilder = SimpleScheduleBuilder.simpleSchedule()
            .withIntervalInSeconds(2) //每2秒执行一次
            .repeatForever(); //永久重复，一直执行下去
    return TriggerBuilder.newTrigger()
            .forJob(jobDetail2())
            .withSchedule(scheduleBuilder).build();
}
