Вот несколько простых шагов, которые помогут вам полностью начать работу с Quartz Scheduler в базе данных MySQL с помощью Groovy. Сценарий ниже позволит вам быстро поэкспериментировать с различными настройками конфигурации Quartz, используя внешний файл.
Первый шаг — настроить базу данных с таблицами. Предполагая, что вы уже установили MySQL и имеете доступ для создания базы данных и таблиц.
bash> mysql -u root -p sql> 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
tables_mysql.sql
можно найти в загрузке дистрибутива Quartz или прямо из их источника здесь . Как только база данных будет запущена, вам нужно написать код для запуска Quartz Scheduler. Вот простой Groovy скрипт
quartzServer.groovy
это будет работать как крошечный сервер планировщика.
// 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)
}
И теперь вам просто нужен файл конфигурации
quartz-mysql.properties
это выглядит так:
# 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
Вы можете запустить Groovy скрипт как обычно
bash> groovy quartzServer.groovy quartz-mysql.properties

That’s a full run of above setup. Go ahead and play with different config. Read http://quartz-scheduler.org/documentation/quartz-2.1.x/configuration for more details.
Here I will post couple more easy config that will get you started in a commonly used config set.
A MySQL cluster enabled configuration. With this, you can start one or more shell terminal and run different instance of quartzServer.groovy with the same config. All the quartz scheduler instances should cluster themselve and distribute your jobs evenly.
# 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
Here is another config set for a simple in-memory scheduler.
# 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
Now, if you need more fancy UI management of Quartz, give MySchedule a try.
