这是一些简单的步骤，可帮助您使用Groovy在MySQL数据库上完全入门Quartz Scheduler。 以下脚本可让您使用外部文件快速尝试不同的Quartz配置设置。

第一步是使用表设置数据库。 假设您已经安装了MySQL，并且有权创建数据库和表。

bash> mysql -u root -psql> create database quartz2;
sql> create user 'quartz2'@'localhost' identified by 'quartz2123';
sql> grant all privileges on quartz2.* to 'quartz2'@'localhost';
sql> exit;bash> mysql -u root -p quartz2 < /path/to/quartz-dist/docs/dbTables/tables_mysql.sql

可以从Quartz发行版下载中找到tables_mysql.sql ，或直接从其源代码中找到 。 数据库启动后，您需要编写一些代码来启动Quartz Scheduler。 这是一个简单的Groovy脚本quartzServer.groovy ，它将作为小型调度程序服务器运行。

// Run Quartz Scheduler as a server
// Author: Author: Zemian Deng, Date: 2012-12-15_16:46:09
@GrabConfig(systemClassLoader=true)
@Grab('mysql:mysql-connector-java:5.1.22')
@Grab('org.slf4j:slf4j-simple:1.7.1')
@Grab('org.quartz-scheduler:quartz:2.1.6')
import org.quartz.*
import org.quartz.impl.*
import org.quartz.jobs.*config = args.length > 0 ? args[0] : 'quartz.properties'
scheduler = new StdSchedulerFactory(config).getScheduler()
scheduler.start()// Register shutdown
addShutdownHook {scheduler.shutdown()
}// Quartz has its own thread, so now put this script thread to sleep until
// user hit CTRL+C
while (!scheduler.isShutdown()) {Thread.sleep(Long.MAX_VALUE)
}

现在，您只需要一个如下所示的配置文件quartz-mysql.properties ：

# Main Quartz configuration
org.quartz.scheduler.skipUpdateCheck = true
org.quartz.scheduler.instanceName = DatabaseScheduler
org.quartz.scheduler.instanceId = NON_CLUSTERED
org.quartz.scheduler.jobFactory.class = org.quartz.simpl.SimpleJobFactory
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.dataSource = quartzDataSource
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5# JobStore: JDBC jobStoreTX
org.quartz.dataSource.quartzDataSource.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.quartzDataSource.URL = jdbc:mysql://localhost:3306/quartz2
org.quartz.dataSource.quartzDataSource.user = quartz2
org.quartz.dataSource.quartzDataSource.password = quartz2123
org.quartz.dataSource.quartzDataSource.maxConnections = 8

您可以照常运行Groovy脚本

以上就是上述设置的完整过程。 继续并使用不同的配置。 阅读http://quartz-scheduler.org/documentation/quartz-2.1.x/configuration以获得更多详细信息。

在这里，我将发布一些更简单的配置，使您开始使用常用的配置集：

MySQL群集启用的配置。 这样，您可以启动一个或多个Shell终端，并使用相同的配置运行quartzServer.groovy不同实例。 所有的石英调度程序实例都应将它们自己群集起来并平均分配您的作业。

# Main Quartz configuration
org.quartz.scheduler.skipUpdateCheck = true
org.quartz.scheduler.instanceName = DatabaseClusteredScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.jobFactory.class = org.quartz.simpl.SimpleJobFactory
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.dataSource = quartzDataSource
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.isClustered = true
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5# JobStore: JDBC jobStoreTX
org.quartz.dataSource.quartzDataSource.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.quartzDataSource.URL = jdbc:mysql://localhost:3306/quartz2
org.quartz.dataSource.quartzDataSource.user = quartz2
org.quartz.dataSource.quartzDataSource.password = quartz2123
org.quartz.dataSource.quartzDataSource.maxConnections = 8

这是一个简单的内存调度程序的另一个配置集。

# Main Quartz configuration
org.quartz.scheduler.skipUpdateCheck = true
org.quartz.scheduler.instanceName = InMemoryScheduler
org.quartz.scheduler.jobFactory.class = org.quartz.simpl.SimpleJobFactory
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5

现在，如果您需要对Quartz进行更高级的UI管理，请尝试使用MySchedule 。

调度愉快！
