spring集成quartz持久化简单应用
最近在做定时跑批任务的时候用开始接触quartz,写了一个简单的demo,由于经验不足,原理还没有深入理解,有什么不对之处还请各位博友加以指正
首先,quartz在与spring集成是是有版本匹配问题的:quartz-1.x与spring3.1之前的版本对应,而quartz2.x与spring3.1之后的版本对应,quartz1和quartz2是有很大区别的。
如下是quartz1.8.6数据库表结构和quartz2.2.1数据库表结构,根据需求构建数据库,见附件
集成spring与quartz:
一、spring3.1之前版本和quartz1.x集成
1、pom依赖(spring和quartz版本自行匹配)
<properties> <spring.version>3.2.9.RELEASE</spring.version> <!--<spring.version>3.0.6.RELEASE</spring.version>--> <!--<spring.version>3.2.2.RELEASE</spring.version>--> <!--<spring.version>4.0.0.RELEASE</spring.version>--> <quartz.version>2.2.1</quartz.version> <!--<quartz.version>1.8.6</quartz.version>--> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!-- quartz --> <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>${quartz.version}</version> </dependency> <!-- mysql begin --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency> <!-- end of mysql --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.16</version> </dependency> </dependencies>2、定义job,实现序列化(内存方式不必实现):(quartz1.x版本)
public class HelloJob implements Serializable{ private static final long serialVersionUID = -2348136105841790133L; public void execute(){ System.out.println("============================"); } }
3、spring配置:
3.1 数据源配置(内存方式忽略此配置)
jdbc.driverClassName=com.mysql.jdbc.Driver #quartz1.x数据库 #jdbc.url=jdbc:mysql://127.0.0.1:3306/quartz-test?useUnicode=true #quartz2.x数据库 jdbc.url=jdbc:mysql://127.0.0.1:3306/quartz2?useUnicode=true jdbc.username=root jdbc.password=maidou jdbc.initialSize=15 jdbc.maxActive=20 jdbc.maxIdle=20 jdbc.minIdle=5
<context:property-placeholder location="classpath:properties/*.properties"/> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!--initialSize: 初始化连接 --> <property name="initialSize" value="${jdbc.initialSize}" /> <!--maxActive: 最大连接数量 --> <property name="maxActive" value="${jdbc.maxActive}" /> <!--maxIdle: 最大空闲连接 --> <!--<property name="maxIdle" value="${jdbc.maxIdle}" />--> <!--minIdle: 最小空闲连接 --> <property name="minIdle" value="${jdbc.minIdle}" /> <property name="defaultAutoCommit" value="true" /><!--这里一定要设置为true,否则在启动项目quartz事务不会自动提交,导致job不能持久化到数据库,抛出异常,正常的程序数据源此项要设置为false,自行控制事务--> <property name="validationQuery" value="SELECT 1 " /> </bean>3.2 quartz配置(quartz1.x):其中jobDetail bean配置的class 需要自己实现序列化,spring 的MethodInvokingJobDetailFactoryBean没有实现序列化,故需要如下两个java文件,见附件
<!-- 调度器 --> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:properties/quartz.properties" /> <property name="autoStartup" value="true" /> <property name="applicationContextSchedulerContextKey" value="applicationContext" /> <property name="startupDelay" value="20" /> <property name="overwriteExistingJobs" value="true" /> <property name="triggers"> <list> <!-- 触发器列表 --> <ref bean="helloJobTrigger" /> </list> </property> </bean> <bean id="helloJobBean" class="com.maidou.job.HelloJob"/> <!-- 触发器 --> <bean id="helloJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail" ref="helloJobDetail" /> <property name="cronExpression" value="0/5 * * * * ?" /> </bean> <bean id="helloJobDetail" class="com.maidou.factory.MethodInvokingJobDetailFactoryBean"> <property name="targetObject" ref="helloJobBean" /> <property name="targetMethod" value="execute" /> <property name="concurrent" value="false" /> <property name="durable" value="true"/> <!--<property name="volatility" value="true"/>--> <property name="shouldRecover" value="true" /> </bean> <import resource="spring-db.xml"/>4、写quartz.properties覆盖原有quartz.properties;如下
#============================================================================ # Configure Main Scheduler Properties #============================================================================ org.quartz.scheduler.instanceName = MY_JOB_SCHEDULER org.quartz.scheduler.instanceId = AUTO org.quartz.scheduler.rmi.export = false org.quartz.scheduler.rmi.proxy = false org.quartz.scheduler.wrapJobExecutionInUserTransaction = false #============================================================================ # 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 #内存方式 #org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore #数据库持久化 org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate org.quartz.jobStore.useProperties=false org.quartz.jobStore.maxMisfiresToHandleAtATime=1 #数据库表名称前缀 org.quartz.jobStore.tablePrefix=QRTZ_ #集群 org.quartz.jobStore.isClustered=false #============================================================================ # Other Example Delegates #============================================================================ #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.CloudscapeDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.DB2v6Delegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.DB2v7Delegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.DriverDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.HSQLDBDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.MSSQLDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.PointbaseDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.PostgreSQLDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.WebLogicDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.oracle.OracleDelegate #org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.oracle.WebLogicOracleDelegate #============================================================================ # Configure Datasources #============================================================================ #org.quartz.dataSource.myDS.driver = com.mysql.jdbc.Driver #org.quartz.dataSource.myDS.URL = jdbc:mysql://10.1.221.118/invest?useUnicode=true&characterEncoding=utf-8 #org.quartz.dataSource.myDS.user = invest #org.quartz.dataSource.myDS.password = invest #org.quartz.dataSource.myDS.maxConnections = 5 #org.quartz.dataSource.myDS.validationQuery= #============================================================================ # Configure Plugins #============================================================================ #org.quartz.plugin.shutdownHook.class = org.quartz.plugins.management.ShutdownHookPlugin #org.quartz.plugin.shutdownHook.cleanShutdown = true #org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPlugin
二、spring3.1之后版本和quartz2.x集成
1、pom文件依赖如上pom依赖(自行匹配spring和quartz版本)
2、定义job,继承 QuartzJobBean:(quartz2.x版本)
public class HelloJob extends QuartzJobBean { @Override protected void executeInternal(JobExecutionContext context) throws JobExecutionException { System.out.println("============================"); } }
3、spring配置:
3.1 数据源配置如上数据源配置
3.2 quartz配置(quartz2.x)配置,可以自定义Listener监听Job和Trigger的执行,分别实现JobListener和TriggerListener接口,如下,见附件
<!--<bean id="myJobListener" class="com.maidou.listener.MyJobListener"/>--> <!--<bean id="myTriggerListener" class="com.maidou.listener.MyTriggerListener"/>--> <!-- 调度器 --> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:properties/quartz.properties" /> <property name="autoStartup" value="true" /> <property name="applicationContextSchedulerContextKey" value="applicationContext" /> <property name="startupDelay" value="20" /> <property name="overwriteExistingJobs" value="true" /> <!-- 可以实现自定义的listener,监听JobListener和TriggerListener,同时自定义的也需要分别实现这两个接口--> <!--<property name="globalJobListeners" ref="myJobListener"/>--> <!--<property name="globalTriggerListeners" ref="myTriggerListener"/>--> <property name="triggers"> <list> <!-- 触发器列表 --> <ref bean="helloJobTrigger" /> </list> </property> </bean> <bean id="helloJobBean" class="com.maidou.job.HelloJob"/> <!-- 触发器 --> <bean id="helloJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="jobDetail" ref="helloJobDetail" /> <property name="cronExpression" value="0/5 * * * * ?" /> <!--<property name="group" value="group1"/>--> <!--<property name="name" value="helloJobTrigger"/>--> </bean> <bean id="helloJobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean"> <property name="jobClass" value="com.maidou.job.HelloJob"/> <property name="group" value="group1"/> <property name="name" value="helloJobDetail"/> <property name="durability" value="true"/> </bean> <import resource="spring-db.xml"/>
4、写quartz.properties覆盖原有quartz.properties;同上
注意:数据源的配置一定要配置成自动提交,默认quartz用的数据库连接池是c3p0,我用的是alibaba的druid。
测试一下
编写测试类:
public class test { private static volatile boolean running = true; public static void main(String[] args) { ClassPathXmlApplicationContext cxt = new ClassPathXmlApplicationContext("classpath:application-context.xml"); synchronized (test.class) { while (running) { try { test.class.wait(); } catch (Throwable e) { } } } } }欢迎留言或到我的csdn博客讨论:http://blog.csdn.net/lingyundouer/article/details/50513194
