How to override quartz's property value

问题

I have spring boot application with it's application.properties file. The project has a dependency on third-party library, in my case its:

<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.3.0</version>
</dependency>

The library has its quartz.properties file with configs. I would like to override some values, e.g.:

org.quartz.threadPool.threadCount:10

to have another number of threads.

How can I do it using my own properties file and/or environment variable?

回答1:

With Spring boot 2 application ( assuming you have the spring-boot-starter-quartz ), you can just specify the properties directly:

spring: quartz: properties: org.quartz.threadPool.threadCount:10

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-quartz.html

Quartz Scheduler configuration can be customized by using Quartz configuration properties ()spring.quartz.properties.*) and SchedulerFactoryBeanCustomizer beans, which allow programmatic SchedulerFactoryBean customization.

回答2:

You can override this value creating your own property resolver:

@Bean
public Properties quartzProperties() throws IOException {
    PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
    propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
    propertiesFactoryBean.afterPropertiesSet();
    return propertiesFactoryBean.getObject();
}

And in your quartz.properties:

#============================================================================
# Configure Main Scheduler Properties
#============================================================================

org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.threadsInheritContextClassLoaderOfInitializer = true
org.quartz.scheduler.skipUpdateCheck = true

#============================================================================
# Configure ThreadPool
#============================================================================

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount: 20
#Thread.MAX_PRIORITY 10
org.quartz.threadPool.threadPriority: 5

#============================================================================
# Configure JobStore
#============================================================================

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

Here you can check code example.
