如何确保使用quartz.properties

Question

我在quartz.properties文件中设置了以下属性：

org.quartz.threadPool.threadCount = 60
org.quartz.scheduler.batchTriggerAcquisitionMaxCount = 60

然而，由于某种原因，它显然没有生效。因为当我启动应用程序时，日志显示它仍然使用池中的1个线程：

[main] INFO org.quartz.impl.StdSchedulerFactory - Using default implementation for ThreadExecutor 
[main] INFO org.quartz.core.SchedulerSignalerImpl - Initialized Scheduler Signaller of type: class org.quartz.core.SchedulerSignalerImpl 
[main] INFO org.quartz.core.QuartzScheduler - Quartz Scheduler v.2.1.1 created. 
[main] INFO org.quartz.simpl.RAMJobStore - RAMJobStore initialized.
[main] INFO org.quartz.core.QuartzScheduler - Scheduler meta-data: Quartz Scheduler (v2.1.1) 'QuartzScheduler' with instanceId 'NON_CLUSTERED' 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 1 threads.**

我知道，quartz.properties需要在类路径上才能找到。我就这么做了。没有检测到该文件的任何其他原因？或者它被检测到但线程数没有正确设置？

感谢

对于那些使用Spring+Quartz且quartz.properties文件不起作用（即在启动应用程序时被忽略）的用户：

Spring Factory Bean（org.springframework.scheduling.quartz.SchedulerFactoryBean）实例化的Quartz Scheduler（org.quartz.Scheduler）默认不会像Quartz文档中所说的那样从类路径读取quartz.properties文件-您需要手动设置引用：

[在Java配置的情况下]：

@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
    SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
    schedulerFactoryBean.setConfigLocation(new ClassPathResource("quartz.properties"));
    // ...
}

[在XML配置的情况下]：

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="configLocation" value="classpath:quartz.properties" />
    // ...
</bean>

oops，我发现了这个问题，实际上代码通过在代码中创建properties class的实例来覆盖属性文件配置。所以答案是这样的：

sf = new StdSchedulerFactory("conf/quartz.properties");

如果有人仍在寻找答案，他们可以使用下面的片段

@Bean                                                                           
public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
    SchedulerFactoryBean scheduler = new SchedulerFactoryBean();
    scheduler.setTriggers(jobOneTrigger());
    scheduler.setQuartzProperties(quartzProperties());
    scheduler.setJobDetails(jobOneDetail());
    return scheduler;
}
@Bean
public Properties quartzProperties() throws IOException {
    PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
    propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
    propertiesFactoryBean.afterPropertiesSet();
    return propertiesFactoryBean.getObject();
}

如果以前的解决方案不适合您，请将属性文件移动到项目的/resource目录中。然后，您的配置将在默认情况下被选中。
