本示例基于spring quartz 1.6.5
1、创建数据库表
//在数据库中建表。建表模版在Quartz包下docs/dbTables下,选择相应的数据库和版本即可。
找到所需要的数据库对应的数据库表即可
2、 配置数据库连接池,如果spring已经配置则不需要再另行配置,只需在后面配置的applicationContext-quartz.xml引入即可。
applicationContext.xml:
<context:component-scan base-package="com.sundoctor"/>
<!-- 属性文件读入 -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
<!-- 数据源定义,使用c3p0 连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${jdbc.driverClassName}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="initialPoolSize" value="5" />
<property name="minPoolSize" value="5" />
<property name="maxPoolSize" value="20" />
<property name="acquireIncrement" value="2" />
<property name="maxIdleTime" value="3600" />
<property name="idleConnectionTestPeriod" value="180"/>
<property name="automaticTestTable" value="C3P0TESTTABLE"/>
</bean>
jdbc.properties
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/lite_basic_db?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true
jdbc.username=root
jdbc.password=123
3、 配置quartz.properties
org.quartz.scheduler.instanceName属性可为任何值,用在 JDBC JobStore 中来唯一标识实例,但是所有集群节点中必须相同。
org.quartz.scheduler.instanceId 属性为 AUTO即可,基于主机名和时间戳来产生实例 ID。
org.quartz.jobStore.class属性为 JobStoreTX,将任务持久化到数据中。因为集群中节点依赖于数据库来传播 Scheduler 实例的状态,你只能在使用 JDBC JobStore 时应用 Quartz 集群。这意味着你必须使用 JobStoreTX 或是 JobStoreCMT 作为 Job 存储;你不能在集群中使用 RAMJobStore。
org.quartz.jobStore.isClustered 属性为 true,你就告诉了 Scheduler 实例要它参与到一个集群当中。这一属性会贯穿于调度框架的始终,用于修改集群环境中操作的默认行为。
org.quartz.jobStore.clusterCheckinInterval 属性定义了Scheduler 实例检入到数据库中的频率(单位:毫秒)。Scheduler 检查是否其他的实例到了它们应当检入的时候未检入;这能指出一个失败的 Scheduler 实例,且当前 Scheduler 会以此来接管任何执行失败并可恢复的 Job。通过检入操作,Scheduler 也会更新自身的状态记录。clusterChedkinInterval 越小,Scheduler 节点检查失败的 Scheduler 实例就越频繁。默认值是 15000 (即15 秒)。
quartz.properties
#==============================================================
#Configure Main Scheduler Properties
#==============================================================
org.quartz.scheduler.instanceName = TestScheduler1
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
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
#==============================================================
#Configure JobStore
#==============================================================
org.quartz.jobStore.misfireThreshold = 60000
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.maxMisfiresToHandleAtATime=10
org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 20000
# Using datasource
org.quartz.jobStore.dataSource = qzDS
#Define the datasource to use
org.quartz.dataSource.qzDS.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.qzDS.URL = jdbc:mysql://localhost:3306/lite_basic_db
org.quartz.dataSource.qzDS.user = root
org.quartz.dataSource.qzDS.password = 123
org.quartz.dataSource.qzDS.maxConnections = 30
4、 配置applicationContext-quartz.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
<bean name="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="applicationContextSchedulerContextKey" value="applicationContextKey"/>
<property name="configLocation" value="classpath:quartz.properties"/>
<property name="triggers">
<list>
<ref bean="trigger1"/>
<ref bean="trigger2"/>
</list>
</property>
</bean>
<bean id="jobDetail1" class="frameworkx.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="simpleService"/>
<property name="targetMethod" value="testMethod1"/>
<property name="shouldRecover" value="true"/>
</bean>
<bean id="trigger1" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="jobDetail1"/>
<property name="cronExpression" value="0/5 * * ? * * *"/>
</bean>
<bean id="jobDetail2" class="frameworkx.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="simpleService"/>
<property name="targetMethod" value="testMethod2"/>
<property name="shouldRecover" value="true"/>
</bean>
<bean id="trigger2" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="jobDetail" ref="jobDetail2"/>
<property name="startDelay" value="1"/>
<property name="repeatCount" value="100"/>
<property name="repeatInterval" value="1000"/>
</bean>
</beans>
5、 配置Job任务注意:加入定时任务有两种方式:
① 继承QuartzJobBean的类,重写executeInternal(),详细写法:
//类信息
public class SimpleService implements Serializable{
private static final long serialVersionUID = 122323233244334343L;
private static final Logger logger = LoggerFactory.getLogger(SimpleService.class);
public void testMethod1(){
logger.info("testMethod1.......1");
}
public void testMethod2(){
logger.info("testMethod2.......2");
}
}
//配置信息
<bean id="jobDetail1" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass">
<value>继承QuartzJobBean的类的引用,如果不继承QuartzJobBean可以参考 http://www.javaeye.com/topic/486055</value>
</property>
</bean>
② 用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean指定类和方法,但是直接使用会报java.io.NotSerializableException异常,一般用网上流传的(需要将两个类copy到自己的工程下,要有springJAR包,Job需要持久化到数据库中,SimpleService必须实现Serializable)frameworkx.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean,可以参考: http://jira.springframework.org/browse/SPR-3797。详细写法:
<bean id="jobDetail1" class="frameworkx.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="simpleService"/>
<property name="targetMethod" value="testMethod1"/>
<property name="shouldRecover" value="true"/>
</bean>
6、启动测试
ApplicationContext springContext = new
ClassPathXmlApplicationContext(new
String[]{"classpath:applicationContext.xml","classpath:applicationContext-quartz.xml"});
启动服务后,spring quartz会将trigger持久化到数据库中
