I want to ask about Spring Boot and Spring MVC.
What is the difference between these components and when should I use them?
How can I use Spring MVC to generate entities from a database?


You can use spring boot to embed a web server into your JAR. So basically you can run a single command (e.g. java -jar yourSpringBoot.jar) and it will start up the embedded web server and listen on whatever port you configured in the application properties file. Spring MVC is a framework, it allows you to build web applications.
For the database question, I would recommend reading about Hibernate and its spring boot integration.


Spring Boot is a framework for running enterprise applications using a simple, all-in-one tool that can configure, build, and run an application.
Spring MVC is a framework for building said application. It is used to create Web application API endpoints, visualizations, database entities, and other stuff. You can configure and run it with Spring Boot or just use the standard Spring configuration system.
If you want to map entities to a database, you can use Spring MVC and Spring Boot. There are plenty of tutorials online, but the basics is like this:
Create a Plain Old Java class with getters and setters (methods like getXXX and setXXX).
Annotate the class with #Entity
Ensure that Spring recognizes that package as containing entities. This can be done with Spring Boot by default when you annotate your Application class with #EnableAutoConfiguration

what is the difference between Spring and Spring MVC framework

I am new to Spring. Can any one let me know what is the difference between Spring and Spring MVC Framework ?

Spring is a big framework, that contains a lot of components. One of these components is Spring MVC - it is a component that lets you implement your web application according to the model-view-controller design pattern.

1- Spring in abstract word is a framework
The Spring Framework is an open source application framework and inversion of control container for the Java platform.
Check this links for more information:
Spring Framework
Framework vs. Toolkit vs. Library
2- MVC architecture
it is an architecture that help the developer to separate the building block of web application.
Model View Controller or MVC as it is popularly called, is a software design pattern for developing web applications
check this link for more information:
Basic MVC Architecture

MVC is a Spring module. You use it for designing web applications. MVC in Spring implements the front controller design pattern. In your web.xml you'll define a single servlet (DispatcherServlet) and all your requests will pass through it and will be attended by Controllers you will define (#Controller).

Spring is a framework which helps to connect different components together. There are many modules for IOC, AOP, Web MVC etc.Spring Framework is an open source application framework and inversion of control container for the Java platform.
Spring MVC (Model–view–controller) is one component within the whole Spring Framework, to support development of web applications.

Spring MVC is one component within the whole Spring Framework, to support development of web applications. You can use any web containers, so it works fine with Tomcat. Just think that Spring is a third party library. You just need to put the necessary jar files in the lib directory, and define a few xml files.
So basically when you just say Spring it is a just a framework. And by framework I mean lot of functionalities/jars. Like you may have core which has core functionality or aspectj etc. Spring MVC i.e model view controller is one such functionality offered by Spring framework. You can deffer processing of request to various controllers based on the pattern of URL requested. You can refer
Spring MVC hello world example

Spring framework can be visualized as an alternative to, replacement for, or even addition to the Enterprise JavaBeans (EJB) model as mentioned here. That means a framework to develop distributed, scalable, secured, transactional application.
Spring MVC can be thought of as an replacement to Struts, Stripes, Tapestry etc, i.e. Presentation layer framework.
Spring framework is the super set of Spring MVC.

Spring
An umbrella term to denote various projects, one of which is Spring Framework.
Spring MVC
The Spring Framework project has several features. One of them is Spring MVC.
Features of Spring Framework are -
Core Technologies: Dependency Injection, validation, data binding, type conversion, SpEL, AOP etc.
Testing
Data Access: Transactions, DAO support, JDBC, ORM etc.
Spring MVC and Spring WebFlux web frameworks.
Integration: JMS, JMX, email, scheduling etc.
Languages: Kotlin, Groovy, dynamic languages.
So, the Spring MVC feature allows developers to build applications following Model-view-controller design pattern using Spring Framework.
Other Spring projects
Spring Boot: For creating stand-alone Spring applications using Convention over configuration design paradigm.
Spring Data: For creating Spring-based programming model for data access. It has various modules like Spring Data JDBC, Spring Data JPA, Spring Data MongoDB etc.
Spring Security: Powerful and highly customizable authentication and access-control framework for both Authentication and Authorization.
And many other projects.
NOTE
Spring, Spring Framework and Spring MVC these terms are often used interchangeably among developers which sometimes creates confusion for people who already don't know the details.

Using Spring HTTP invoker between difference versions of spring?

I have a server which uses spring 2.5.6 and currently my client spring mvc application are also using same version 2.5.6. I use httpinvoker for the connection between the two. I want to update and benefit of spring mvc 3, but I can not do anything with the server.
My questions is:
Will it work to use a different version of spring on the web-application than on the server-side?
And can this have side-effects that can cause problems?

Can i learn Spring MVC directly for web sites rather than basic Spring

Firstly, I want to know is Spring and Spring MVC different things.
IF they are different then can I jump directly to Spring MVC because I want to build website
and I have very less time to experiment and I want to start as soon possible.
Will spring MVC is sufficient without using hibernate or anything which I need to learn.
I know only core Java.

Spring MVC builds on top of Spring. So you need to know basics of Spring to use Spring MVC. And you doesn't need to learn Hibernate.

does spring provide 2 mvc platforms, grails and spring mvc?

Just reading spring in action, and I know there is a chapter on MVC that I havent' got to yet.
I also read about grails, is that another framework or built on top of spring?

Yes, Grails is built on Spring (and several other frameworks) and it uses Spring MVC to implement its MVC layer.
