In the BE based category, you’ll delve into the hidden world behind the scenes, where code dictates what users experience and interact with. Here, efficiency reigns supreme. Swift data processing and information transfer are the hallmarks of a stellar BE. To conquer this realm, we’ll equip you with essential tools like mapping and polymorphism, master the art of error handling, and build robust security measures. Whether you’re a seasoned architect or a curious beginner, this is your gateway to unlocking the power of backend development. Buckle up and get ready to explore the magic that happens before a user sees a single line of code!
In the world of Spring Boot applications, data modeling plays a crucial role and JPA @Enumerated is here for that. JPA provides an elegant way to map Java classes to database tables, while the @Enumerated annotation empowers you to seamlessly represent enumerations as database columns. This article delves into the […]
To talk about lambda functions and functional programming we must first talk about functional interfaces. A functional interface is an interface with one and only one abstract method. They have a special relationship with lambda expressions.From Java 8 we can find many functional interfaces in java.util.function package. A functional interface […]
Today we will see how to implement a ModelMapper that allows us, for example, to transform an object with many properties into a smaller object with fewer properties. This transformation can be useful when we need leaner objects, perhaps in a list, or when we want to expose only some […]
Java streams are sequences of data elements that can be processed with operations. Streams consist of 3 parts: a source, zero or more intermediate operations, and a terminal operation.In the meanwhile there is a data in pipe, another data is waiting its turn. For instance, for a data in terminal […]
The move toward microservices and distributed architectures has made stateful session management increasingly difficult to scale. In a standard REST environment, the server should not be required to store session information about the client. JSON Web Tokens (JWT) have emerged as the industry standard for handling authentication in a stateless […]
