Description

Are you a professional, Willing to enter Spring Framework World?

Is your employer asking for 'Spring Framework' as a skill? But you don't have it?

Do you wish, that there is a beginner friendly Spring Framework Tutorial?

Or do you just want to get started with Spring Framework?


Well, you are in the right place. Welcome to this course on 'Spring Core Framework '!


Spring Core is the starting point for learning spring framework, and having a solid understanding on the core concepts of spring would not only ease your journey to learn other modules/projects of spring, but also to clear interviews.

This course will cover all the required & essential spring core concepts in great detail along with examples.

Spring is lightweight, extensible, robust framework (or rather framework of frameworks!) for creating enterprise applications that are easy to maintain.

Spring Core' is the core module that comes with an embedded servlet container (IOC Container) and would enable the core functionalities of spring. You can think of Spring Core as the core engine on which other modules would run.

This course is taught in beginner friendly way and the only expectation from you, is that you know Java.

I’ve been dealing with Spring Projects since 2012 and been teaching since 2015. I’ve also taught/mentored many individuals worldwide and helped them reach their goals.

Few random reviews on my teaching style

★★★★★

“Easy to follow. Nice explanations. Great course…anyone can learn no matter of the previous level of programming knowledge”


★★★★★

“This instructor seems very knowledgeable, and covers topics that seem very important ”

★★★★★

“This course is really worth it. The tutor has ample practical knowledge and discusses about almost everything that is there to know. I am glad i took this course and would encourage any aspirant to go for it.”

★★★★★

“Good, clear instructor with uncluttered focused examples – recommended.”

★★★★★

“Liking the course so for. Very good explanation of each concepts, explaining the fundamentals on each topic, all the way till what happens in memory in each, explaining the “Why’s” in the beginning of topic (which is very important to me, otherwise one would be just memorizing). I liked the author’s approach to start with explaining methods and then expanding it to classes, objects and others. This course is good value for the money.”


Knowledge Notes!


What is Cpring Core?

Spring core is the core module that is built on key spring principles like Dependency Injection and Inversion of Control (Discussed in the course!).

All there rest of the spring Modules/Projects relay on Spring Core Module.

What is dependency injection?

Before spring, all the software components used to be tightly coupled with each other where making changes in one component would require other component to be altered.

With spring, developers will not define the dependencies themselves, instead they'd ask the Spring Container to inject he required dependency right when the application is booted. Objects define their associations (dependencies) and do not worry about how they will get those dependencies. It is the responsibility of Spring container to provide the required dependencies.

In other words, instance creation is taken care by the container and would be injected in components that ask for it. There by promoting a loosely couple architecture, where one component will not be impacted due to the changes in other dependent component.


What is Inversion of Control (IOC)?

In simple terms, Inversion of Control (IOC) means, that the responsibility of creating the instance is given the underlying container.

Dependency injection is one such pattern to achieve Inversion of Control. However, there are many more approaches to achieve IOC (Ex: Service locator pattern, Strategy Design Pattern, etc)


What is Application Context in Spring?

Application context is responsible for instantiating the beans, configure and wire them together depending on their dependencies. How how does the AppliationContext know of what beans to configure and how they are dependent on other objects? It will take at the config file where we define all the beans.

Traditionally we use XML as the config to define our beans, but it comes with a lot of drawbacks. For example, there is no syntax highlighting making it difficult to manage for large projects.

A better approach is the more recent Java config which is much more convenient and provides a lot of flexibility in terms of configuring beans.

Even modern, we don't have to even define our beans. We can ask Spring to scan the objects for us. But how does spring know which components to scan and create instances? Well, it will just simply create an instance of all the beans that are annotated with any of these annotations

@Component

@Controller

@Repository

@Service


org.springframework.context.ApplicationContext is the interface that defines the contract for Spring Core IOC container.

There are several implementations of ApplicationContext and we need to use the one depending on our needs. For example, if you want to go with good old XML config, ClassPathXmlApplicationContext is the implementation to use.
