আমি বসন্তে জবস্টোরটিএক্স স্ট্রিন্ট স্টোর ব্যবহার করে একটি কোয়ার্টজ জব কনফিগার এবং সময়সূচী পরিচালনা করেছি আমি স্প্রিংয়ের কোয়ার্টজ কাজগুলি ব্যবহার করি না, কারণ আমি তাদের চলাকালীন সময়ে গতিশীলভাবে শিডিউল করা দরকার, এবং কোয়ার্টজের সাথে স্প্রিংকে সংহত করার সমস্ত উদাহরণ যা আমি পেয়েছি যে স্প্রিং কনফিগারেশন ফাইলগুলিতে শিডিউলগুলি হার্ড-কোডিং ছিল ... যাইহোক, এখানে কীভাবে হয় আমি কাজের সময়সূচী:
JobDetail emailJob = JobBuilder.newJob(EMailJob.class)
.withIdentity("someJobKey", "immediateEmailsGroup")
.storeDurably()
.build();
SimpleTrigger trigger = (SimpleTrigger) TriggerBuilder.newTrigger()
.withIdentity("someTriggerKey", "immediateEmailsGroup")
.startAt(fireTime)
.build();
// pass initialization parameters into the job
emailJob.getJobDataMap().put(NotificationConstants.MESSAGE_PARAMETERS_KEY, messageParameters);
emailJob.getJobDataMap().put(NotificationConstants.RECIPIENT_KEY, recipient);
if (!scheduler.checkExists(jobKey) && scheduler.getTrigger(triggerKey) != null) {
// schedule the job to run
Date scheduleTime1 = scheduler.scheduleJob(emailJob, trigger);
}
ইমেলজব একটি সহজ কাজ যা স্প্রিংয়ের জাভামেলসেন্ডারআইএমপিএল ক্লাসটি ব্যবহার করে ইমেল প্রেরণ করে।
public class EMailJob implements Job {
@Autowired
private JavaMailSenderImpl mailSenderImpl;
public EMailJob() {
}
public void execute(JobExecutionContext context)
throws JobExecutionException {
....
try {
mailSenderImpl.send(mimeMessage);
} catch (MessagingException e) {
....
throw new JobExecutionException("EMailJob failed: " + jobKey.getName(), e);
}
logger.info("EMailJob finished OK");
}
সমস্যাটি হ'ল আমার ই-মেইলজব ক্লাসে এই শ্রেণীর (জাভামেলসেন্ডারআইএমপিএল) উদাহরণের একটি রেফারেন্স পাওয়া দরকার get যখন আমি এটির মতো ইঞ্জেক্ট করার চেষ্টা করি:
@Autowired
private JavaMailSenderImpl mailSenderImpl;
এটি ইনজেকশনের নয় - রেফারেন্সটি NULL। আমি ধরে নিচ্ছি যে এটি ঘটছে কারণ এটি স্প্রিং নয় যারা ইমেইলজব ক্লাসটি ইনস্ট্যান্ট করে তবে কোয়ার্টজ এবং কোয়ার্টজ নির্ভরতা ইনজেকশন সম্পর্কে কিছুই জানেন না ...
সুতরাং, এই ইঞ্জেকশনটি ঘটতে বাধ্য করার কোনও উপায় আছে?
ধন্যবাদ!

আপডেট # 2: @ রায়ান:
আমি নীচে স্প্রিংবিয়ানজব ফ্যাক্টরিটি ব্যবহার করার চেষ্টা করেছি:
<bean id="jobFactoryBean" class="org.springframework.scheduling.quartz.SpringBeanJobFactory">
</bean>
<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="configLocation" value="classpath:spring/quartz.properties"/>
<property name="jobFactory" ref="jobFactoryBean"/>
</bean>
এবং আমি এই কারখানাটি থেকে কোয়ার্টজ-এর পরিবর্তে এই কারখানাটি থেকে শিডিয়ুলার পেতে আমার মূল শ্রেণিকে সংশোধন করেছি:
@PostConstruct
public void initNotificationScheduler() {
try {
//sf = new StdSchedulerFactory("spring/quartz.properties");
//scheduler = sf.getScheduler();
scheduler = schedulerFactoryBean.getScheduler();
scheduler.start();
....
তবে আমি যখন অ্যাপটি চালাচ্ছি - ত্রুটিগুলি পান, নীচে দেখুন। স্প্রিং স্টার্টআপ থেকে স্ট্যাকট্রেস এখানে। সময়সূচীটি নিজেই সূক্ষ্মভাবে তৈরি হয়েছে বলে মনে হয়, তবে ত্রুটি তখনই আসে যখন এটি আমার ইমেইলজব ইনস্ট্যান্ট করার চেষ্টা করছে:
