quartz自定义线程数

1.加载包

2.添加quartz.propertes

3.编写自己的任务类

4.添加自动任务配置

5.通过 quartzProperties 配置连接池

1.加载包

<dependency>
            <groupId>quartz</groupId>
            <artifactId>quartz</artifactId>
            <version>1.5.1</version>
        </dependency>

<dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-context-support</artifactId>  
            <version>${spring.version}</version>
        </dependency> 

2.添加quartz.propertes

从quartz.jar中copy一份quartz.properties 放在项目资源目录下

修改线程池数量

org.quartz.threadPool.threadCount = 1

# Default Properties file for use by StdSchedulerFactory
# to create a Quartz Scheduler Instance, if a different
# properties file is not explicitly specified.
#

org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
#thread pool count
org.quartz.threadPool.threadCount = 1
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true

org.quartz.jobStore.misfireThreshold = 60000

org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

3.编写自己的任务类

com.qi.task.RiskManagermentJob

4.添加自动任务配置

需要添加 

 <property name="configLocation" value="classpath:quartz.properties"></property>
不添加，配置的线程池数将不生效。

    <bean id="CronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="SpringQtzJobMethod"></property>
        <property name="cronExpression" value="2/60 * 15 * * ?"></property>
    </bean>

<!--     ======================== 调度工厂 ======================== -->
    <bean id="SpringJobSchedulerFactoryBean"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="CronTriggerBean" />
            </list>
        </property>
        <property name="configLocation" value="classpath:quartz.properties"></property>
    </bean>
    
</beans>

5.通过 quartzProperties 配置连接池

<bean id="SpringJobSchedulerFactoryBean"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="CronTriggerBean" />
            </list>
        </property>
        <property name="quartzProperties">
            <props>
                <prop key="org.quartz.threadPool.threadCount">1</prop>
            </props>
        </property>
        <!-- 方式二 -->
<!--         <property name="configLocation" value="classpath:quartz.properties"></property> -->
    </bean>
