springboot+quartz搭建

一、工程目录

 

二、源码例子

（1）添加依赖

<!-- quartz -->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.1</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.2.1</version>
        </dependency>
        <dependency>
            <groupId>javax.transaction</groupId>
            <artifactId>jta</artifactId>
            <version>1.1</version>
        </dependency>

 

（2）quartz配置文件

#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName = org.quartz.scheduler.instanceId = AUTO
#============================================================================
# Configure ThreadPool
#============================================================================
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5
#===================================================
# Configure the Job Initialization Plugin
#===================================================
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = E:\\MyProject\\springboot\\platform\\target\\classes\\config\\quartz_jobs.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 100
org.quartz.plugin.jobInitializer.wrapInUserTransaction = false

 

（3）quartz_jobs配置文件

<?xml version='1.0' encoding='utf-8'?>
<job-scheduling-data xmlns="http://www.quartz-scheduler.org/xml/JobSchedulingData"
                     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                     xsi:schemaLocation="http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_1_8.xsd"
                     version="1.8">
    <schedule>
        <job>
            <name>MyJob</name>
            <group>MyJobGroup</group>
            <description>The job description</description>
            <job-class>com.demo.platform.common.job.MyFirstJob</job-class>
        </job>
        <trigger>
            <cron>
                <name>MyTrigger</name>
                <group>MyTriggerGroup</group>
                <job-name>MyJob</job-name>
                <job-group>MyJobGroup</job-group>
                <cron-expression>0/5 * * * * ?</cron-expression>
            </cron>
        </trigger>
    </schedule>
</job-scheduling-data>

 

（4）监听器（初始化quartz）

@WebListener
public class MyListener implements ServletContextListener {
    @Override
    public void contextInitialized(ServletContextEvent servletContextEvent) {
        StdSchedulerFactory factory = new StdSchedulerFactory();
        try {
            ResourceLoader resourceLoader = new DefaultResourceLoader();
            Resource resource = resourceLoader.getResource("classpath:config/quartz.properties");
            File configFile = resource.getFile();
            FileInputStream fin = new FileInputStream(configFile);
            Properties file = new Properties();
            file.load(fin);
            factory.initialize(file);
            Scheduler scheduler = factory.getScheduler();
            scheduler.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void contextDestroyed(ServletContextEvent servletContextEvent) {

    }
}

 

（5）主程序添加注解（@ServletComponentScan）

@SpringBootApplication
@ServletComponentScan
public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }

}

 

（6）定义job

public class MyFirstJob implements Job {
    @Override
    public void execute(JobExecutionContext context) {
        System.out.println("======== 我是第一个定时任务，哈哈哈 ==========");
    }
}
