Quartz和Spring Boot的问题

Question

So I have a technical challenge I need help with.

A large scale project is using a Quartz scheduler to schedule a job to run every night at 9.
The Job that is scheduled, however needs to read values from property files, get some beans using auto-wiring etc.

When I used @Autowired and @Value annotations, I found the values to be null.

The issue is that Quartz creates JobDetail objects using newJob() outside the spring container. As can be seen in the below code.

JobKey jobKey = new JobKey("NightJob", "9-PM Job");
JobDetail jobDetail = newJob(NightJob.class).withIdentity(jobKey)
                     .usingJobData("Job-Id", "1")
                     .build();

The jobDetail object which wraps NightJob thus cannot access property files or beans using spring.

Here is my NightJob class

public class NightJob implements Job{

    //@Value to read from property file; here
    //@Autowired to use some beans; here

    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException{
    }
}

I scanned Stack Overflow and shortlisted several solutions. I also read through the comments and listed the top counter-comments.

Suggestion 1: Get rid of Quartz and use Spring Batch due to its good integration with Spring Boot

Counter argument 1: Spring Batch is overkill for simple tasks. Use @Scheduled

Suggestion 2: Use @Scheduled annotations and cron expressions provided by spring

Counter argument 2: Your application will not be future ready if you remove Quartz. Complex scheduling may be required in the future

Suggestion 3 : Use the spring interface ApplicationContextAware.

Counter argument 3: Lots of additional code. Defeats the simple and easy concept of Spring boot

Is there a simpler way in Spring Boot to access property file values and autowire objects in a class that implements a Quartz job (In this situation , the NightJob class)

如注释中所述，Spring通过提供setter方法来支持将Bean注入Quartz作业： https : //docs.spring.io/spring-boot/docs/current/reference/html/boot-features-quartz.html
