Task scheduler configured by XML is not eligible for getting processed by all BeanPostProcessors #34015
Description
Hello!
Seems like XML-based scheduling configuration from documentation produces well-known "is not eligible" warning.
Minimal sample
Tested on Spring Core versions: 6.1.15, 6.2.0.
applicationContext.xml:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd"> <task:scheduler id="scheduler" pool-size="5" /> <task:annotation-driven scheduler="scheduler" /> </beans>Main.java:
import org.springframework.context.ConfigurableApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Main { public static void main(String[] args) { new ClassPathXmlApplicationContext("applicationContext.xml"); } }Starting results in singular log message:
WARNING: Bean 'scheduler' of type [org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying). Is this bean getting eagerly injected/applied to a currently created BeanPostProcessor [org.springframework.context.annotation.internalScheduledAnnotationProcessor]? Check the corresponding BeanPostProcessor declaration and its dependencies/advisors. If this bean does not have to be post-processed, declare it with ROLE_INFRASTRUCTURE. Unfortunately, I haven't found any way to mark this bean as infrastructure using only XML.
