- Looking for a complete Spring MVC tutorial for beginners?
But at the same time, you don't want to be spoon fed with something at the level of a Spring Boot Hello World app? If so, this Spring Web MVC tutorial is for you.
In this tutorial we start a Spring Boot and Spring MVC project from scratch.
We then incrementally add Controller, RequestBody, GetMapping ResponseBody, Id and Repository Spring annotations (among others) to create a comprehensive Spring CRUD Web MVC project that actually implements a simple little rock-paper-scissors game.
If you want to learn Spring MVC quickly, and really understand how Spring MVC and Spring Boot work together, this fun Spring MVC course is for you!
For a full Spring MVC tutorial, check out the long-form article I wrote over at TheServerSide:

Now, I'm going to paste some AI generated stuff below to capture keywords. Don't read it. Read the article I wrote instead.
********************************
Spring MVC (Model-View-Controller) is a powerful framework within the Spring ecosystem, primarily used for building web applications. Its usefulness stems from several key features:
Separation of Concerns: Spring MVC adheres to the MVC design pattern, which separates the application logic into three interconnected components:
Model: Represents the data and business logic.
View: Handles the presentation layer and user interface.
Controller: Manages user input, processes it, and updates the model and view accordingly.
Comprehensive Configuration Options: Spring MVC can be configured using XML, Java annotations, or Java-based configuration classes, offering flexibility and ease of setup.
Integration with Other Spring Projects: Spring MVC integrates seamlessly with other Spring projects like Spring Boot, Spring Security, Spring Data, and Spring Cloud, making it a versatile choice for building robust and scalable web applications.
RESTful Web Services: Spring MVC simplifies the creation of RESTful web services, allowing easy mapping of HTTP requests to controller methods.
Key Annotations in Spring MVC
@Controller: Marks a class as a Spring MVC controller, capable of handling web requests.
@RequestMapping: Maps HTTP requests to handler methods of MVC and REST controllers. It can be applied at the class level and/or method level.
@RequestMapping("/path") at the class level specifies the base path for all methods within the class.
@RequestMapping("/methodPath") at the method level specifies the path for a specific method.
@GetMapping, @PostMapping, @PutMapping, @DeleteMapping, @PatchMapping: Specialized versions of @RequestMapping for common HTTP methods:
@GetMapping: Handles HTTP GET requests.
@PostMapping: Handles HTTP POST requests.
@PutMapping: Handles HTTP PUT requests.
@DeleteMapping: Handles HTTP DELETE requests.
@PatchMapping: Handles HTTP PATCH requests.
@RequestParam: Binds a method parameter to a web request parameter.
@RequestParam("name") String name binds the request parameter "name" to the method parameter name.
@PathVariable: Binds a method parameter to a URI template variable.
@PathVariable("id") Long id binds the URI template variable id to the method parameter id.
@RequestBody: Binds the body of the web request to a method parameter, typically used for handling JSON data in RESTful services.
@ResponseBody: Indicates that the return value of a method should be used as the response body, often used in RESTful services to directly return JSON or XML responses.
@ModelAttribute: Binds a method parameter or return value to a model attribute, used for form binding.
@SessionAttributes: Specifies the names of model attributes that should be stored in the session.
@ExceptionHandler: Defines a method to handle exceptions thrown by request-handling methods within the controller.
Spring MVC in the Context of Spring Boot
Spring Boot simplifies the development of Spring applications by providing a range of features, including:
Auto-configuration: Automatically configures your Spring application based on the dependencies present in the classpath. This eliminates much of the boilerplate configuration.
Embedded Servers: Comes with embedded servers like Tomcat, Jetty, or Undertow, making it easy to run Spring applications without external server setup.
Starter Dependencies: Provides a set of convenient dependency descriptors that you can include in your application. For instance, spring-boot-starter-web includes Spring MVC, embedded Tomcat, and other necessary libraries.
Spring Boot Actuator: Provides production-ready features like metrics, health checks, and monitoring.
Spring Boot DevTools: Enhances the development experience by providing features like automatic restarts, live reload, and configurations for better development workflow.
In summary, Spring MVC is an essential part of the Spring ecosystem
your tutorials are really good so dont worry about being boring
These 1hour beginner crash courses are pretty nice. Honestly, you are very good at teaching. You explain everything without over-explaining. This makes it easier to get an idea of what the code you're typing does while keeping the whole video entertaining. I'd like to add that I think unique junior projects like these, or ones just a little bit more complex that apply to real-world scenarios, could be great.
Thanks so much for the kind words! While I try not to over-explain, I do think I move quickly and demand a lot from the viewer. My videos tend to be a bit beyond a simple 'hello world', so if you like the pace, that's an indication that you're pretty smart yourself. As for building a more complicated app, that's completely my intention. I want to go through the basic Spring projects and technologies with the fun Rock Paper Scissors App, and then do something with a bit more teeth as I pull it all together in something that should confuse and intimidate just about everyone.
Thanks again for watching and commenting!
you are an amazing teacher so have confidence i went through a lot of tutorials but yours is very very clear and to the point and it works and at the end it is understood. ( very few give this level of quality).
This one ends on some Spring Data API stuff, so it really is a whirlwind tour. Even JavaScript client hitting the REST API. It's a very advanced tutorial!
Awesome intro tutorial! I appreciate how you even explained the difference between a @Controller and @RestController.
Would love to see a Spring Security tutorial, maybe with login and signUp flows!
Thanks for the kind words! Honestly though, Spring MVC gets all the credit. The framework makes everything so easy. All I did was click a few buttons.
This has honeslty become the channel for me to come to for Spring - Keep it up mate
Thanks for the kind words! That's high praise given how many other great content creators there are in the Spring community!
Waoo.. your videos makes lot of sense.. Thank you so much. you are helping me understand the Spring framework in easy way.
Thanks for the support! I really enjoyed putting this Spring web MVC tutorial together. It was fun.
Great Job
Thanks! Loved putting this Spring MVC tutorial together!
Brilliant.
I worked hard on this Spring web MVC tutorial to try and keep is fairly simple, yet cover fairly complex Spring Boot topics. I'm glad you liked it!
We need a real world project please 👏🏻
Well, the title does say 'beginners.' So I'm trying not to overwhelm anyone just starting out. RESTful APIs and Spring JDBC with a fun example is a nice place to start.
I'll put together a more intense microservices development tutorial in the near future for you. Stay tuned! Let me know what you'd like to see included.
@@cameronmcnz jdbc template with spring mvc and testing would be nice from you legend ❤️
Spring mvc plus spring security and jdbc template would be nice from you legend ❤️
I use thymeleaf for my personal projects
Don't tell anyone, but I'm still using Servlets and JSPs.
@@cameronmcnz They are good
