Why isn't Spring running my @Scheduled method?

Question

I\'m a bit befuddled because I\'m trying use use @Scheduled annotations, but Spring doesn\'t seem to be finding my methods. The end result is that, none of my m

Answer 1

In spite of that I am using Spring 3.1.2, I am running into the same problem in case i place my executor and scheduler tag in ApplicationContext.xml. i have two xml configuration file for spring in my project which are :

1. applicationContext.xml
2. dispatcher-servlet.xml

So try to move your configuration to the last configuration file which spring reads. in my case it is start working by moving my configuration to dispatcher-servlet.xml

here is my example:

applicationContext.xml

Answer 2

So...it looks like there's a problem in Spring 3.0.x (at the very least 3.0.4 and 3.0.5) having to do with discovering @Scheduled annotations on AOP proxies. I've got a pointcut declaration wrapping the @Scheduled method with transactional advice, and that seems to be the root of the problem. If I remove the advice, the job runs. If I add it back in, Spring fails to find and create a task for my annotated method.

So, I'm going to go file a bug with the Spring folks, and in the meantime I'm stuck declaring my tasks manually.

Answer 3

The only difference that I see from my setup (which works), is that my class is annotated with @Component rather than @Service. Other things to check:

• whether you have the proper jars on the classpath (spring-context, I think)
• put a breakpoint and check whether it really isn't executing
• double-check the cron expression (I admit I always consult the docs for that). Or use a fixed delay, just to check if it works
• try upgrading to 3.0.5 or the latest 3.1 snapshot.

Answer 4

add "task:annotation-driven" ?

<beans> <!-- XMLNS, XSD declarations omitted for brevity -->

  <context:component-scan base-package="com.mypackage"/>
  <task:annotation-driven/>
  <task:executor id="executor" pool-size="5"/>
  <task:scheduler id="scheduler" pool-size="5"/>
  <task:annotation-driven scheduler="scheduler" executor="executor"/>

</beans>

reference http://howtodoinjava.com/2013/04/23/4-ways-to-schedule-tasks-in-spring-3-scheduled-example/

or

Spring @Configuration (non-xml configuration) for annotation-driven tasks

Just add @EnableScheduling on you WebMvcConfig class

@Configuration
@EnableWebMvc
@EnableAsync
@EnableScheduling
public class WebMvcConfig extends WebMvcConfigurerAdapter {
   /** Annotations config Stuff ... **/
}

reference Spring Scheduler does not work

Answer 5

I fixed it by adding default-lazy-init="false" to my applicationContext.xml.

<beans .....
    **default-lazy-init="false"**>

Answer 6

This is pretty old question but since this keeps up coming in google search results let me add the solution that worked for me in Spring 5. For me it didn't work until I added @Component to the class having @Scheduled annotated methods.
