For the convenience of CodeGym students, we decided to collect lectures and articles on the most important topics in programming. The ninth selection is about the Spring family of frameworks. In the mini-guide, we briefly outline the essence of the articles, and if you follow the link, you can learn more about the topic of interest. Add a collection to your bookmarks and return to it when you need to.
In this two-part article, the author writes about the basic concepts of the Spring framework: what is Spring, beans, and context. We suggest you start learning the framework by reading this text. Moreover, the author provided it with code examples.
The second part of the article deals with writing a trial project in Spring. If in the first part the author explained the theory, then in the second he decided to focus on practice.
The article will talk about the history of the framework, key differences from the Java EE stack. The author also made a small overview of the key components of the Spring stack.
The purpose of this series of articles is to give the student the minimum necessary theoretical knowledge for further study of JavaEE or Spring. All material is divided into 7 parts: network, client-server and three-tier architecture device, HTTP/HTTPS protocols, Maven, servlets and servlet containers, and MVC.
An article that, in simple language with examples understandable to a 5-year-old child, talks about what the framework in general and Spring in particular are. If you are just starting to study the IT world, this text will help you understand it.
If you have already figured out the Spring Framework and Spring Boot, it's time to learn Spring MVC. Spring MVC is a component or design pattern of the Spring Framework that allows you to develop web applications in Java using the Model-View-Controller architecture, which means that it will come in handy in your future work as a programmer.
Now that you've covered Spring Boot theory, it's time to put it into practice. The series of articles “Spring is not scary” will help with this. In short texts with code examples, the author talks about various situations in which Spring is used: working with databases, handling exceptions in controllers, connecting Lombok, and more.
The article is intended for those who have already worked with this framework in one way or another and are familiar with the basic concepts. The author considers how the framework works “under the hood”.
The author talks about his first exposure to things like Maven, Spring, Hibernate, MySQL, and Tomcat while building a simple CRUD application. The article is intended primarily for those who have already passed 30-40 levels of CodeGym, but beyond pure Java for now didn’t get out and is just starting to go out into the open world with all the technologies, frameworks and other unfamiliar words.
To Teach or Not to Teach Spring Boot? Definitely teach! In this review text, the author reveals the main advantages and disadvantages of using Spring Boot. But we have already read the article - the benefits turned out to be much greater. Follow the link and see for yourself.
This material is the final part of the "Introduction to Enterprise Development" series. Already from the name it is clear that we will talk about creating an application on Spring Boot. By opening the text, you will receive step-by-step instructions in order to launch the application yourself.
Of course, you can simulate a future interview for a developer position on your own. But it is better to use ready-made questions and answers that have already been written and collected in this article.
Not a single new Java project is complete without the use of Spring Boot Starters. Using them allows you to save time on configuration and focus on designing the application and solving business problems. But sometimes there is a need to implement your own starter, since the existing ones do not provide the necessary functionality. In this video, the developer creates his starter from scratch.
If you are confused about the universe of Java and Spring frameworks, we recommend watching this video. It explains the difference and how to use Spring Boot, Spring MVC and Servlet.
In the video tutorial, in live coding mode, the developer creates a Spring Boot application that will parse news on a schedule, store data in the database, display news using the REST API, and divide it all into layers for a scalable project architecture.
The video has collected the most interesting questions that are asked at technical interviews for a Java developer. The video consists of two parts. The first one talks about Java Collections, Hash Code & Equals Contract, Functional interfaces, Stream API, Garbage collector, memory device, heap, concurrency. In the second part of the video you will learn about Spring: Spring Beans, Spring Data Repository, Annotations, Programmatic TM and Spring MVC.
