介绍
Quartz是OpenSymphony开源组织在Job scheduling领域又一个开源项目，它可以与J2EE与J2SE应用程序相结合也可以单独使用。Quartz可以用来创建简单或为运行十个，百个，甚至是好几万个Jobs这样复杂的程序。Jobs可以做成标准的Java组件或EJBs。Quartz的最新版本为Quartz 2.3.2。
quartz可以在某一个有规律的时间点干某件事，是一个任务调度框架，可以被集成到java的各种应用中使用，quartz框架可以支持分布式任务处理
基于springboot创建的web项目整合Quartz框架

创建quartz_demo数据库，执行tables_mysql_innodb.sql文件创建对应表，下面是文件内容
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

# I didn't see this anywhere, so I thought I'd post it here. This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.

创建一个Job实现类，只是一个简单实现类，没有对方法添加参数
@Slf4j
@Component
public class QuartzJobImpl implements Job {
@Autowired
private ApplicationContext context;
@SneakyThrows
@Override
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
SysJob sysJob = new SysJob();
BeanUtils.copyProperties(jobExecutionContext.getMergedJobDataMap().get("QuartzJobExecutionData"), sysJob);
log.info("正在执行任务");
String invokeTarget = sysJob.getInvokeTarget();
String beanName = invokeTarget.split("\\.")[0];
String methodName = invokeTarget.split("\\.")[1];
Object bean = context.getBean(beanName);
Class<?> clazz = bean.getClass();
Method method = clazz.getMethod(methodName);
method.invoke(bean);
log.info("已结束任务");
System.out.println();
}
}
创建最终任务执行类，执行函数级别的定时任务，数据库中的invoke_target是和这里放入spring中的名称相同的，quartz_target.hello最终执行的函数就是hello函数
@Slf4j
@Component("quartz_target")
public class QuartzJobExe {
@Resource
private Scheduler scheduler;
public void hello() throws Exception {
System.out.println("[job]实例执行...hello..." System.currentTimeMillis());
}
public void action() throws Exception {
System.out.println("[job]实例执行...action..." System.currentTimeMillis());
}
}
最终代码结构
启动spring boot之后的任务状态
使用postman工具类添加一个任务
然后在代码中添加一个对应的方法
重新启动springboot的运行结果
理论上使用这样的反射方式可以运行任何代码的
