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
<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("============================"); } }
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
