设置石英线程池的线程数

Question

我创建了文件quartz.properties并将其放在classpath中。属性是

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 1

但是当我启动应用程序时，我收到了这条消息

Scheduler class: 'org.quartz.core.QuartzScheduler' - running locally.
NOT STARTED.
Currently in standby mode.
Number of jobs executed: 0
Using thread pool 'org.quartz.simpl.SimpleThreadPool' - with 10 threads.
Using job-store 'org.quartz.simpl.RAMJobStore' - which does not support persistence. and is not clustered.

是加载属性还是不加载？无论如何我只为调度程序运行一个线程...

Answer 1

当我使用spring时，我确实喜欢这个。我在我的常见properties文件中创建了一个属性

quartz.threadPool.threadCount=1

然后在我的xml中设置quartzProperties的字段ScheduleFactoryBean

<property name="quartzProperties">
    <util:properties>
        <prop key="org.quartz.threadPool.threadCount">
            ${quartz.threadPool.threadCount}
        </prop>
    </util:properties>
</property>

@NikNik

org.quartz.threadPool.threadCount数据类型必须是String所以它应该是

p.put（“org.quartz.threadPool.threadCount”，“2”）;

...

StdSchedulerFactory factory = new StdSchedulerFactory(p);

Answer 3

它可能没有加载您的属性文件。但是，要避免使用属性，可以使用java配置来配置调度程序：

Properties p = new Properties();
p.put("org.quartz.scheduler.instanceName", "Scheduler_test");
p.put("org.quartz.threadPool.threadCount", 2);
...
StdSchedulerFactory factory = new StdSchedulerFactory(p);

如果您使用带注释的弹簧配置：

@Bean
public SchedulerFactoryBean schedulerFactoryBean() {        
    SchedulerFactoryBean scheduler = new SchedulerFactoryBean();
    Properties quartzProperties = new Properties();     
    quartzProperties.put("org.quartz.threadPool.threadCount", "1");
    scheduler.setQuartzProperties(quartzProperties);
    ...
    return scheduler;
}
