Why is Spring framework so popular ?

by devs5003 - 0

We have various frameworks in Java. Spring framework is most popular out of them. Some other commonly used frameworks are Struts, JSF, but Spring has already dominated all of them. Let's understand why is Spring framework so popular ?. At its core, the Spring Framework includes the principles of simplicity, modularity, and loose coupling. It provides developers with a unified programming model that simplifies the complexities of enterprise application development. With its popular dependency injection mechanism, Spring allows the creation of highly modular and testable code. It also makes developers free from the burden of managing complex dependencies manually. Before directly coming to 'Why is Spring Framework so Popular ?', let's first understand the basic terminology 'What is a Framework?'. What is

Java Scheduler: How to Schedule a Job in Java Spring Boot Scheduler

by devs5003 - 45

Sometimes we come across a situation when we expect a task should execute only at a particular point of time or re-execute within a particular time interval. Simultaneously, our client expects a functionality to be executed at a particular time on an hourly basis, daily basis, weekly basis, monthly basis or even some other as well. In fact, in all these types of situations we implement scheduling to get the requirements fulfilled accordingly. For example, one of the most popular implementation is the report generation at a particular time. On the other hand, almost every client expects this functionality to have in the project. Currently the most popular one is the PDF report. Consequently, our topic 'Java Scheduler: How to Schedule

If you are working in a project where spring is being used, you must have heard about the term 'Spring Dependency Injection'. If not, this is the right time to dig into it as much as possible without further delay. Needless to say, Spring dependency Injection is the heart of the whole Spring Framework. I would also suggest you to go through the practical knowledge of it. However, it is also true that someone can't understand the concept of Spring Dependency Injection only having the theoretical knowledge. If you are expecting to learn all the basic and crucial concept behind the Spring Dependency Injection step by step, and if you don't want to revise the concept more than a hundred times

Profiles In Spring Boot

by devs5003 - 4

When we work on a real time project, we maintain multiple environment for the same project. This happens because we use different infrastructures for different stages of the project. There are different useful environments that we maintain before making the project go live, such as: development (DEV), test, user acceptance testing (UAT), production (PROD). These environments are not fixed at all. Some projects may have some more environments or even sometimes less also. It totally depends on the decisions made by stakeholders involved in the specific project and its requirements. Spring Framework offers us to maintain a separate profile for each environment in order to switch over the environments with a minimal effort. Hence, our topic of discussion is 'Profiles In

No one can deny from the fact that Security is a vital feature of a production ready application. Although we can secure one web application using In-memory authentication, JDBC Authentication or via UserDetailsService. But when one application uses the services of other application internally, then implementation of security with webservices concept becomes important. In this situation we secure our application using a token which has a particular period of validity. In this article, we are going to learn 'How to implement JWT Authentication in Spring Boot Project?' to understand the concept behind JWT(JSON Web Token) Authentication as a whole. As JWT stands for 'JSON Web Token', it is clear that the token holds the data in the form of JSON only. Moreover,

Sometimes in real time projects, we need to transfer data from one location to another. If the volume of data is small, we can achieve this by applying any traditional approach. On the other hand, if there is a huge amount of data, we can make use of the Spring Batch API to make the transfer of data faster and performant. In this article 'Spring Batch Example CSV to MySQL Using JPA', we are going to transfer the data from CSV file to MySQL database using Spring Boot Batch. We have already discussed theoretical concepts of Spring Batch in a separate article 'Spring Batch Tutorial'. Now, its time to implement our example 'Spring Batch Example CSV to MySQL Using JPA'. What will
