我正在使用Spring批处理应用程序来使用java配置执行两个批处理作业。最近我添加了一个Spring调度程序来安排我写的一个Job。侦听器在作业完成时首次调用，但在下次执行后不会被调用。以下是我的工作配置代码：
@Component
public class AnomalyScheduler {
private Job myImportJob;
private JobLauncher jobLauncher;
@Autowired
public AnomalyScheduler(JobLauncher jobLauncher, @Qualifier("anomalyJob") Job myImportJob){
this.myImportJob = myImportJob;
this.jobLauncher = jobLauncher;
}
@Scheduled(fixedDelay=60000)
public void runJob(){
try {
jobLauncher.run(myImportJob, new JobParameters());
} catch (JobExecutionAlreadyRunningException | JobRestartException
| JobInstanceAlreadyCompleteException
| JobParametersInvalidException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
以下是我的计划程序的代码：
public class AnomalyJobListener extends JobExecutionListenerSupport {
private PushNotification pushNotification = PushNotification
.getPushNotificationInstance();
@Autowired
public AnomalyJobListener(MongoTemplate mongoTemplate,
UserRepository userRepository) {
List<AnomalyBean> anomalies = new ArrayList<AnomalyBean>(0);
anomalies = mongoTemplate.findAll(AnomalyBean.class);
int numAnomalies = anomalies.size();
List<UserBean> admins = new ArrayList<UserBean>(0);
admins = userRepository.userByType("admin");
if (numAnomalies > 0) {
for (UserBean admin : admins) {
pushNotification.pushNotification(numAnomalies
+ " anomalies detected ! Keep an eye on that.",
admin.getDeveiceId());
}
}
}
}
我的听众如下：

这是控制台输出：
{{1}}
请告诉我我做错了什么，为什么听众没有被执行后续尝试。
答案 0 :(得分：0)
您的侦听器构造函数中只有代码。但不是在beforeJob（）afterJob（）或任何其他方法......所以我猜这个监听器被调用但什么也没做...... 所以你需要覆盖适当的监听器方法。
