Quartz 有分 内存方式 和 数据库方式
内存方式任务信息保存在内存中, 停机会丢失, 需手动重新执行, 数据库方式: 任务信息保存在数据库中, 重点是支持集群.
内存方式 RAMJobStore 和 数据库方式 JobStoreTX, RAMJobStore 适合单机, 不支持集群, JobStoreTX 支持集群.
下面介绍的就是 JobStoreTX 数据库方式.
1. 添加主要的相关依赖, 其他依赖这里就不说了
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
</dependency>
2. quartz 的数据库表目前有 11 个, 可以下载官方包, 在官方包中可以找到建表语句, 对应不同的数据库有相应的sql语句.
配置文件 quartz.properties

/**

*/
@PostMapping("/createJob")
public void createJob(@RequestBody JobInfo jobInfo) {

import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.QuartzJobBean;
import com.codingos.springboot.service.Job1Service;
public class Job1 extends QuartzJobBean {
@Autowired
private Job1Service job1Service;
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
job1Service.service1();
}
}
7. JobInfo 类
public class JobInfo {
private String jobName;
private String jobGroup;
private String jobClassName;
private String triggerName;
private String triggerGroup;
private String schedulerName;
private String prevExecuteTime;
private String nextExecuteTime;
private String cron;
private String triggerState;
public JobInfo() {
}
public String getJobName() {

}
public String getPrevExecuteTime() {
return prevExecuteTime;
}
public void setPrevExecuteTime(String prevExecuteTime) {
this.prevExecuteTime = prevExecuteTime;
}
public String getNextExecuteTime() {

}
public void setNextExecuteTime(String nextExecuteTime) {
this.nextExecuteTime = nextExecuteTime;
}
public String getJobClassName() {
return jobClassName;

最后, 说一下, 如果是 SpringBoot 2.x 集成 Quartz 框架, 添加依赖就非常方便了
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
