Is Spring Boot difficult to learn? (2024)

Is Spring Boot difficult to learn?

To answer your questions, Spring is easy to learn because the whole framework is designed to work with POJOs, instead of relying on special interfaces, abstract classes or such.

To learn Spring Framework Basics like Dependency Injection, Bean Life Cycle, Autowiring, MVC, AOP(Aspect Oriented Programming), it should take around 50+ Hrs, assuming spending about 2 to 3 hrs, in about 30 days(approximately) & it also depends on your prior expertise/experience, you will get some confidence.

In fact, I suggest all first-timers start with Spring Boot, it's better to start with the latest and popular technology than traditional ones, btw, if you still want to start with Spring first, then you should first check out the Spring Framework 5: Beginner to Guru before going through any of these Spring Boot courses ...

It made the development of Web applications much easier than compared to classic Java frameworks and Application Programming Interfaces (APIs), such as Java database connectivity (JDBC), JavaServer Pages(JSP), and Java Servlet.

Why ? Because Spring Boot hijacks ${property} constructs and you have to use @property@ for it to work again. Way too many issues with accidental dependencies. Auto configuration is a black box which you can't possibly understand let alone replace with manual configuration.

You can't. Spring is a big hairy framework covering a lot more than just MVC J2EE applications. It would be like trying to learn Arabic, Chinese, Swahili, Pidgin and Basque in the same two weeks.

No, Spring is a framework for java, which is built in core java, even if you use spring you will have to write java code, hence you should have strong knowledge on core java, and spring is just a framework not programming language, likewise what ever framework you use, first you should know the programming language.

Spring Boot is built on Spring. You can't use Spring Boot without Spring at all. However, you can choose your path of learning. It is indeed possible, and I also recommend that you start with Spring Boot and then gradually learn the essentials of Spring.

So… Is Spring Boot in demand in 2022? Short answer: yes, it is, and it will most likely stay in demand in the years to come.

What are the disadvantages of Spring Boot?

Disadvantages of Spring Boot

Large deployment files that result from unused dependencies. The long amount of time that it takes to replace legacy systems with Spring Boot applications. Its inability to build large, monolithic applications (although it works extremely well for developing microservices)

If you want your application to do a large amount of computing such as in Big Data, eCommerce or IoT, then it is better to go the Spring Boot way. However, wherever applications need a lot of I/O, such as in media apps, booking systems, and finance technology apps, Node. js is a better choice.

Spring Boot is considered a module of the Spring framework for packaging the Spring-based application with sensible defaults. Spring MVC is considered to be the model view controller-based web framework under the Spring framework. For building a Spring-powered framework, default configurations are provided by it.

Now here are a few particular things I hate about Spring: It really slows down your app's startup time. You won't find out if your app works or not, until you run it - in large commercial environments it can mean up to an hour build and deployment time.

However, Spring Boot has a number of uses that do not require a web server: console applications, job scheduling, batch or stream processing, serverless applications, and more. In this tutorial, we'll look at several different ways to use Spring Boot without a web server.

Spring and JEE are complicated. Because they are designed to solve very complex problems. They are not worth using in simple applications. Spring has come up with Spring Boot, which reduces this complexity.

Yes. Good to know is servlets JSP. I would recommend you to learn spring Mvc at first.

Spring Boot in itself has nothing to do with microservices. It's a Spring module which simply makes the configuration of your app easier. As such, it absolutely can be used in a monolithic app.

If you want to develop web applications especially micro-services, I will recommend that you should learn Spring Boot first. The first reason is that there are many resources and examples on web, so you can easily find what you need.

Should I learn Servlet before Spring Boot?

Short answer: no, you don't need to learn Servlets and JSPs as a pre-requisite for Spring MVC and many other Java web frameworks.

If you know java basic concepts like core java than you can learn within 3–4 months java and spring boot as well..

If you want your application to do a large amount of computing such as in Big Data, eCommerce or IoT, then it is better to go the Spring Boot way. However, wherever applications need a lot of I/O, such as in media apps, booking systems, and finance technology apps, Node. js is a better choice.
