ฉันจัดการกำหนดค่าและกำหนดเวลางาน Quartz โดยใช้ร้านค้าถาวร JobStoreTX ใน Spring ฉันไม่ได้ใช้งาน Quartz ของ Spring เพราะฉันต้องการกำหนดเวลาแบบไดนามิกในเวลาทำงานและตัวอย่างทั้งหมดของการรวม Spring กับ Quartz ที่ฉันพบคือการเข้ารหัส shcedules ในไฟล์ config Spring อย่างยากลำบาก ... อย่างไรก็ตามนี่คือวิธี ฉันกำหนดเวลางาน:
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);
}
EMailJob เป็นงานง่ายๆที่ส่งอีเมลโดยใช้คลาส JavaMailSenderImpl ของ Spring
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");
}
ปัญหาคือฉันจำเป็นต้องได้รับการอ้างอิงถึงอินสแตนซ์ของคลาสนี้ (JavaMailSenderImpl) ในคลาส EMailJob ของฉัน เมื่อฉันพยายามฉีดมัน:
@Autowired
private JavaMailSenderImpl mailSenderImpl;
ไม่ได้ฉีด - การอ้างอิงเป็นโมฆะ ฉันสมมติว่าสิ่งนี้เกิดขึ้นเพราะไม่ใช่ฤดูใบไม้ผลิที่สร้างอินสแตนซ์คลาส EMailJob แต่ Quartz และ Quartz ไม่รู้อะไรเกี่ยวกับการฉีดแบบพึ่งพา ...
ดังนั้นมีวิธีใดบ้างที่จะบังคับให้การฉีดยานี้เกิดขึ้นได้?
ขอบคุณ!
อัปเดต 1: @Aaron: นี่คือส่วนที่เกี่ยวข้องของ stacktrace จากการเริ่มต้นซึ่งแสดงให้เห็นว่า EMailJob ถูกสร้างอินสแตนซ์สองครั้ง:

ขอบคุณ!
อัปเดต # 2: @Ryan:
ฉันพยายามใช้ SpringBeanJobFactory ดังต่อไปนี้:
<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>
และฉันได้ปรับเปลี่ยนคลาสหลักของฉันเพื่อรับ Scheduler จากโรงงานนี้แทนที่จะเป็น Quartz ':
@PostConstruct
public void initNotificationScheduler() {
try {
//sf = new StdSchedulerFactory("spring/quartz.properties");
//scheduler = sf.getScheduler();
scheduler = schedulerFactoryBean.getScheduler();
scheduler.start();
....
แต่เมื่อฉันเรียกใช้แอป - ได้รับข้อผิดพลาดโปรดดูด้านล่าง นี่คือ stacktrace จาก Spring startup ดูเหมือนว่า Scheduler นั้นสร้างขึ้นได้ดี แต่ข้อผิดพลาดเกิดขึ้นเมื่อพยายามสร้างอินสแตนซ์ EMailJob ของฉัน:
