spring-scheduled

问题 I am using the @Scheduled annotation from Spring framework to invoke a method. But I have multiple nodes in my setup and I do not want them to all run at exactly the same time. So I'd like to set a random value to the initial delay to offset them from each other. import org.springframework.scheduling.annotation.Scheduled; @Scheduled(fixedRate = 600000, initialDelay = <random number between 0 and 10 minutes> ) Unfortunately, I am only allowed to use a constant expression here. Is there any

问题 I have two scheduled tasks that I want to run in parallel. These two tasks execute a Spring Batch job. One every 15 seconds and the other ever 3 seconds. The problem is one will be running and the other is blocked until it finishes. I can't seem to find a similar question or example anywhere. Any ideas? Thanks, /w Here's a bit of my configuration. I'm using spring-task-3.2 and spring-batch-2.2 with Spring 3.2. This batch job is ran by the mappingRunScheduler . The other task runScheduler is

问题 I have two resource servers: one that has an API for emailing notifications and one that runs scheduled tasks. When a scheduled task starts, I want to call out to the email service to notify users that their task is starting. Both services use OAuth2 for authentication. The scheduled task service has client credentials set up so that it can get an access token by presenting it's client credentials: To accomplish this, I'm using Spring Boot with Spring Security OAuth2. The Task service has an

问题 How can I use @Scheduled annotation of spring dynamically? CronTrigger(String expression, TimeZone timeZone) http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/scheduling/support/CronTrigger.html#CronTrigger-java.lang.String-java.util.TimeZone- As I have multiple timeZones in database, how can I pass them dynamically? I tried this in my code: TimeZone timezone = null; String timezone1 = null; public SchedulerBean(String timezone2) { this.timezone1 = timezone2; /
