I need to know whether the Spring Framework or any of the other projects e.g. Boot have ECCN classifications.
And would also like to know whether a table of Spring projects vs. ECCN exists.
There is no official communication from Spring Community.
The fact is Spring frameworks have no entry in the Commerce Control List (CCL) so they have no Export Control Classification Number (ECCN).
They are designed as EAR99.

I want to know what spring dependencies should I use on my website to make the work easy and spring or spring boot which one is better. also, suggest some frontend technologies that I can use to make the website smart.
It's a very broad question. And it all depends on what features you want in your web site. Just listing few basic module to give you some hints.
Spring MVC - For web application with MVC Pattern
Spring Security - To secure your app
Spring ORM - If using any ORM tool like hibernate
You need to explore more on the basis of your need.
Spring Boot vs Spring:
You should use Spring Boot if you are starting new project. Spring Boot came to make development process easier when using Spring Framework. In Spring, developer had to write lots of code to configure beans and dependencies. Spring Boot automated this process so that you no longer do it by yourself but Spring Boot will take care of it. Plus it provides some extra tools (In built Web Server, in Memory DB, tool to monitor and manage Spring Boot App )
Try to create a simple web app in Spring and Spring Boot to understand the difference.
Front-end Technologies:
JavaScript based framework/lib like Angular,React,Vue etc. are the trend for front-end now a days. Again there are pros and cons of each of them. Hence you need to evaluate, what suits you better as per your requirement.
My team currently has an old JSF 1.1 / Spring2 / Weblogic Monolith Application. As we start towards modernizing our application they want us to take our current architecture, as is, and basically shoe horn it into Spring Boot.
We aren't talking about breaking it down into micro-services at this point, but basically a lift from our current setup, taking Weblogic out of the picture, and running it in Spring Boot with Hikari Data Sources.
Can this be easily done? I haven't found a way to do it without extensive code changes and I don't mind suggesting a "Lets break it down into a micro-services in the next Product Increment" approach.
Outside of re-architecting our application (as we plan in the future) or doing quite a lot of code change, are there any other options?
If you do not use JavaEE for Weblogic, you can migrate your application to the Spring Boot easy enough. The main thing is the correct import of configuration, components, resources and properties. See: example.
If you used in your legacy project JPA or even JDBC to rewrite backend to Spring Data is not very difficult.
From my point of view the main difficulty is the JSF version you are using. I would refuse it, because: 1) it is not fully compatible with Spring boot and 2) it is already out of date today. It takes a lot of effort to put it into the Spring Boot and still it will not work completely. If there is no time and resources to change this view technology to another, you will have to finish it to Spring Boot.
I don't see other real alternatives
Is there a way to create a simple CRUD App using Spring Boot and an Existing Database?
You could look at Spring Roo. Its entire purpose is to allow rapid application generation. There is also support for reverse engineering an app from an existing database.
Version 2 will apparently also support Spring Boot, but I don't know if database reverse engineering already made it into v2. You could always try generating your application and adding Spring Boot later on.
I haven't much used it myself so unfortunately I can't offer you much guidance on its actual use - but you should be able to find some tutorials on Google, and StackOverflow contains several questions and answers on Spring Roo as well.
Can anyone clarify what are the differences between Spring Framework, Spring ROO, and Spring MVC ? I am really puzzled by these similar terms and cannot mangage find an answer.
It's really easy:
Spring Roo is a DEVELOPMENT-TIME tool, similar to Eclipse, IntelliJ, etc.
Spring Framework is a RUN-TIME framework.
Applications generated with Spring Roo at development time use Spring Framework at run time.
Hope this helps.
I do not want to be rude, but also from SO tags we know:
spring
The Spring Framework is an open source framework for application development on the Java platform. At its core is rich support for component based architectures, and it currently has over a dozen highly integrated modules.

spring-mvc
Based on the Model-View-Controller (MVC) pattern, Spring MVC helps you build web-based applications that are flexible and decoupled from the underlying view technologies.

Via an intuitive command line interface it supports operations such as Java web project creation, persistence configuration and view scaffolding.

My own brief description would be: Spring framework is the framework providing some functionalities for example dependency injection. Spring MVC is for creating web projects as you mentioned already. Finally Spring Roo is a tool, that helps you increase productivity, I'd say that instead of manual configuration changes you are using this tool.
Hopefully, this was not too brief...
I am new to Spring. Just having basic understanding of it.
I am curious to know, can we use Spring MVC Framework and other components of Spring framework (like AOP) together?
Thanks!
Briefly yes.

Spring could potentially be a one-stop shop for all your enterprise applications, however, Spring is modular, allowing you to pick and choose which modules are applicable to you, without having to bring in the rest. You can read details about modules available in Spring Framework.Here
