[FIXED] Any replacement for locatorFactorySelector in Spring 5.3.7

Issue

We are using Spring 4.3.5 in our application. While we try to uplift the Spring to 5.3.7, we are not able to initialize beans(inside "beanRefFactory.xml") inside the below tag-

<context-param>
        <param-name>locatorFactorySelector</param-name>
        <param-value>/beanRefFactory.xml</param-value>
    </context-param> 

Upon searching we found that "locatorFactorySelector" or "LOCATOR_FACTORY_KEY_PARAM" have been deprecated in Spring 5.0.0.M5. Details can be found here.

Kindly suggest if there is any other way to initialize "beanRefFactory.xml". We are using XML based configuration.

PS: have already gone through the answers, but no help.

Solution

I solved this by creating a custom class BeanFactoryContextLoader.java which extends ContextLoaderListener.

public class BeanFactoryContextLoaderListener extends ContextLoaderListener {
    
    private static Logger log = Logger.getLogger(BeanFactoryContextLoaderListener.class);
    
     @Override
        protected ApplicationContext loadParentContext(ServletContext servletContext) {
            
         ApplicationContext ctx = new ClassPathXmlApplicationContext("beanRefFactory.xml");
         
         return ctx;
        }

}

This worked for me. By default Spring return null for the method "loadParentContext". You need to override it. This might give you some insight.
