ApplicationContext and ServletContext

Question

I get confused between the two ApplicationContext and ServletContext when it comes to Spring MVC Application. I know that There is just only One ApplicationContext per Sprin

Answer 1

They are separate things. Every Java web applications based on Servlet technology will have a servlet context, whether it's a spring application or not. In contrast, the ApplicationContext is a Spring thing; in very simple terms, it's a container to hold Spring beans.

To initiate the value for both ApplicationContext and ServletContext, in web.xml, we will add something in context-param tag.

It would help if you quote an example for this, because, as far as I know, context-param is used for ServletContext, and not ApplicationContext.

Update:

You can use a context-param to provide the locations of the root application context configuration files, as below.

    contextConfigLocation
    
        /WEB-INF/root-context.xml
        /WEB-INF/applicationContext-security.xml
