When comparing Spring MVC vs Vaadin, the Slant community recommends Spring MVC for most people. In the question“What are the best Java web frameworks?” Spring MVC is ranked 1st while Vaadin is ranked 7th. The most important reason people chose Spring MVC is:
The official documentation covers virtually everything. The official website also has a series of great tutorials in video and text formats. There are links to Github repositories for Spring sample applications and there are also a lot of third-party tutorials out there for the fact that Spring MVC is so widely used by many experienced developers.
Question Ranking
Pros
Pro Great documentation that covers almost everything
The official documentation covers virtually everything. The official website also has a series of great tutorials in video and text formats. There are links to Github repositories for Spring sample applications and there are also a lot of third-party tutorials out there for the fact that Spring MVC is so widely used by many experienced developers.
Pro Spring MVC has a massive community
Being the oldest and most used JVM web framework, means that Spring MVC has a massive community of followers who are very helpful and have provided numerous tutorials and answers on SO.
Spring even holds an annual conference called SpringOne. The Spring forums and SO are great places to ask and get help about anything Spring related. The website blog and newsletter keep developers informed on every news related with the framework.
Pro Spring apps are highly scalable
Applications are meant to scale as the framework is used in large-scale applications worldwide. Components like EhCache are used to scale memory cache and it also contains components used for parallel processing.
Batch enables processing of large volumes of records and job processing statistics.
Pro Spring has an extensive ecosystem
It is based and is dependent on the Spring Framework, therefore it benefits from tools like for example Roo and Spring Tool Suite and many more tools included in the Spring Framework. All Maven dependencies are available in a public Maven repository.
There are also 3rd-party solutions for Spring, such as MyEclipse which includes scaffolding capability for Spring MVC.
Pro Compiles Java to JavaScript
Vaadin uses GWT to compile Java code into JavaScript. This means that developers using Vaadin can write both frontend and backend code in Java.
Pro Easy to use
Vaadin has a 'design mode' which allows developers to drag and drop components into a canvas and then provide the logic for every component. There are also a lot of third party tutorials and guides which help with the initial learning curve.
Pro Top notch documentation
The book of Vaadin is a must have for every developer that uses Vaadin to make web apps. It is an excellent reference manual and all around a great tool for every Vaadin related need. You can find and download the pdf online or get it for free in almost any Vaadin sponsored conference.
The online documentation is also very good. It has some tutorials and video guides.
There is also a vibrant community which sorround Vaadin, for any problem you may have there is a big chance that someone has already asked and answered that question on StackOverflow or in the Vaadin forums. If not, it will probably be answered quickly if you ask it.
Pro Modern, configurable theming
Vaadin comes with the Valo Theme, a Sass-based theme and engine that calculates styles based on configurable variables and making it easy to define a completely new theme with a few lines of SCSS.
Pro Easy to develop prototypes quickly
Vaadin has what is called the Vaadin Directory which is a repository of downloadable Vaadin components which can be easily used for development. To use something from the repository, you need to download the JAR file and add it to the project.
Cons
Con Updating and code maintenance can be a grueling task if you are a beginner
Updating your project is manageable if you’re already familiar with the framework and the project itself, but if you’re just diving in it can be a little overwhelming and hard.
Con Bloated legacy DI API
Spring DI is bloated and rather complex in comparison to CDI.
Con Complex and not newbie friendly
Spring MVC architecture although simple has a lot of layers and abstractions which can be hard to debug if problems arise. It is also highly dependant on the Spring core.
It's an old and mature framework that has numerous amount of ways to extend and configure it – and this actually makes it fairly complex.
Con Lacking in UI development
While actually very good and with a very complete and rich feature set to develop and maintain code on the server side, it still doesn't provide any rich framework for building good user interfaces.
Con Unnecessarily slow, bloated, complex, convoluted, wordy, and verbose
Spring is convoluted and XML-ridden. Deploying things on the JVM has always been a pain in the nipple and nothing has changed much since the 90s. All things Java-related are wordy, verbose, and a waste of developer time.
Con Slow Prototyping
If you are looking to build a quick prototype fast and easy, Spring isn't going to help much. It's very large and quite hard to grasp if you are just beginning with it.
Con Weak scalability
Since Vaadin stores the UI state and logic in the server, this means that for every user interaction a request needs to be sent to the server and the client needs to wait so it can know how to react. This leads to higher traffic and load times.
