I have a property that i need to change on the fly.

As beans are created and autowired on startup, even if i change the bean during runtime is not taking into effect.

Ex:

Class serviceA {

   Instant instant;
}


@Configuration
Class config {

   @Bean
   Instant instant() {
      return instant.now();
   }
}

Now if i have a request header to use a time(sent as header in rest call) i need to use that time to create a instant and use it instead of the above bean.

Is there a way to refresh a aingle bean (Instant in this case) as this is autowired in multiple classes and i want to refresh only those classes to update the instant dependency.

I dont think this is advisable to update the autowired beans during runtime, any ither suggestions or better appeochaes to handle this?

Or if i can use Instant bean how do i refresh the instant bean and also where it is injeced?

Appreciate in advance.
