spring boot - exclude bean from component scan does not work in XML

Question

I need to exclude these two packages based on any conditional value from an external source before running my application.

Since I need to determine these packages based on an external value before building , I cant use hardcoded annotations.

@ComponentScan( basePackages = "com.ReadDB.reader", excludeFilters = { @ComponentScan.Filter(type = FilterType.REGEX, pattern = "com\.ReadDB\.reader\.opendental\.."), @ComponentScan.Filter(type = FilterType.REGEX, pattern = "com\.ReadDB\.reader\.mysql\..") } )

this annotation on my main class is working ,

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
           http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.ReadDB.reader">
        <context:exclude-filter type="regex" expression="com\.ReadDB\.reader\.opendental\..*"/>
        <context:exclude-filter type="regex" expression="com\.ReadDB\.reader\.mysql\..*"/>
    </context:component-scan>

</beans> 

but this xml file in my resources folder and @ImportResource("classpath:applicationContext.xml") annotation on my main class is not working.

Any idea on how to fix this.
