How to solve the problem of non-execution of scheduled tasks by schedule in springboot

This article introduces the relevant knowledge of "how to solve the problem of non-execution of scheduled tasks in schedule in springboot". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

@ schedule annotation is a common scheduled task annotation in springboot, which is simple and convenient to use, but if there are a lot of scheduled tasks, or some tasks are time-consuming, it will affect the execution of other scheduled tasks, because schedule is single-threaded by default, and other tasks cannot be executed when one task is executed. The solution is to reconfigure schedule to multithreaded execution. Just add the following configuration class.

Import org.springframework.boot.autoconfigure.batch.BatchProperties;import org.springframework.context.annotation.Configuration;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.scheduling.annotation.SchedulingConfigurer;import org.springframework.scheduling.config.ScheduledTaskRegistrar;import java.lang.reflect.Method;import java.util.concurrent.Executors;@Configurationpublic class ScheduleConfig implements SchedulingConfigurer {@ Override public void configureTasks (ScheduledTaskRegistrar taskRegistrar) {Method [] methods = BatchProperties.Job.class.getMethods (); int defaultPoolSize = 3; int corePoolSize = 0 If (methods! = null & & methods.length > 0) {for (Method method: methods) {Scheduled annotation = method.getAnnotation (Scheduled.class); if (annotation! = null) {corePoolSize++;}} if (defaultPoolSize > corePoolSize) corePoolSize = defaultPoolSize;} taskRegistrar.setScheduler (Executors.newScheduledThreadPool (corePoolSize)) This is the end of the content of "how to solve the problem of non-execution of scheduled tasks in schedule in springboot".
