InternalResourceViewResolver is one of the built-in view resolvers in Spring MVC. As the name implies, its primary purpose is to resolve views internally without going through the dispatcher servlet. This is useful when working with static pages or resources that do not need to go through the controller layer.  To configure InternalResourceViewResolver, you need to set the prefix and suffix properties. The prefix property specifies the path to the resources, while the suffix property specifies the file extension. For example, if you set the prefix to "/WEB-INF/jsp/" and the suffix to ".jsp", InternalResourceViewResolver will look for resources in the "/WEB-INF/jsp/" directory and will use the ".jsp" extension.  In addition, you can also set properties such as viewClass and contentType. ViewClass specifies the class that will be used to generate the view, while contentType specifies the content type of the response. By default, InternalResourceViewResolver uses JstlView to generate views.
