Spring Boot整合Quartz框架

说明：Quartz是一个定时器框架，可以实现定时任务，本文介绍如何在Spring Boot项目中整合Quartz框架，Quartz介绍参看下面这篇文章：

【Quartz】Quartz定时任务框架

创建Demo

首先，创建一个Spring Boot项目，pom文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.12</version>
        <relativePath/>
    </parent>

    <groupId>com.hezy</groupId>
    <artifactId>quartz_demo</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

</project>

引入quartz

在pom文件中，添加下面依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>

引入依赖后就可以使用了，Spring Boot向来很方便。首先，创建一个定时任务，如下：

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
 
public class SampleJob implements Job {

    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        // 你的业务逻辑
        System.out.println(System.currentTimeMillis() / 1000 + "===============定时任务开始执行了……");
    }
}

然后，创建定时任务的配置类，配置类配置定时任务的周期等信息，如下：

import com.hezy.job.SampleJob;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import static org.quartz.SimpleScheduleBuilder.simpleSchedule;

@Configuration
public class QuartzConfig {

    /**
     * 定义JobDetail，关联具体的Job
     */
    @Bean
    public JobDetail sampleJobDetail() {
        return JobBuilder.newJob(SampleJob.class)
                .withIdentity("sampleJob").storeDurably().build();
    }

    /**
     * 关联Trigger
     * 定时任务，每隔10秒执行一次
     */
    @Bean
    public Trigger sampleJobTrigger() {
        return TriggerBuilder.newTrigger().forJob(sampleJobDetail())
                .withIdentity("sampleTrigger")
                .withSchedule(simpleSchedule().repeatForever()
                        .withIntervalInSeconds(10))
                .build();
    }
}
