Full syllabus: every lesson in the Spring Boot roadmap
11 stages and 46 lessons, in the order the roadmap suggests. Every lesson is free to read and open from the start.
Stage 1: Introduction
Introduction
Spring Boot is a framework for building applications based on the Spring Framework, a widely-used, open-source framework for building Java-based enterprise applications. Spring Boot aims to make it easy to create stand-alone, production-grade Spring-based applications that you can "just run".
Terminology
Spring Core, the base of the Spring Framework, provides a model for configuring Java applications. Key concepts include Beans (Java objects managed by Spring), Inversion of Control (IoC) (Spring managing bean lifecycles and dependencies), and Dependency Injection (DI) (Spring providing bean dependencies). The…
Architecture
Spring Boot follows a layered architecture in which each layer communicates with the layer directly below or above (hierarchical structure) it. The four layers in Spring Boot are as follows:
Why use Spring?
Spring Boot provides a number of features that make it easier to create a Spring-based application, including:
Configuration
Spring Core Configuration is the process of configuring the Spring Framework, which involves specifying the various configuration details required for an application to function properly. This can include setting up beans, specifying bean dependencies, configuring aspect-oriented programming (AOP) aspects, and…
Dependency Injection
Spring Boot uses the Spring Framework's Inversion of Control (IoC) container to manage objects and their dependencies. The IoC container is responsible for creating objects, wiring them together, and managing their lifecycle. When an object is created, its dependencies are also created and injected into the object.
Spring IOC
Inversion of Control (IoC) is a design pattern that is often used in conjunction with the Dependency Injection (DI) pattern. The basic idea behind IoC is to invert the flow of control in a program, so that instead of the program controlling the flow of logic and the creation of objects, the objects themselves…
Spring AOP
Spring AOP (Aspect-Oriented Programming) is a feature of the Spring Framework that allows developers to define certain behaviors (i.e., "aspects") that cut across multiple classes, such as logging or transaction management. These behaviors, which are called "advices," can be applied to specific "join points" (i.e.,…
Spring MVC
Spring MVC is a framework for building web applications in Java. It is part of the Spring Framework, which is a larger ecosystem of tools for building Java applications. Spring MVC is built on the Model-View-Controller (MVC) design pattern, which helps to separate the concerns of the application into three distinct…
Annotations
One of the key features of Spring Boot is its use of annotations, which are used to configure various aspects of the application and to enable certain features.
Spring Bean Scope
In the Spring Framework, a bean is an object that is instantiated, assembled, and managed by the Spring IoC container. One of the key features of the Spring container is its ability to manage the lifecycle of beans, which includes creating, configuring, and destroying beans as necessary. One way the container can…

Stage 6: Hibernate
Hibernate
Hibernate is a Java framework that provides an object-relational mapping to an object-oriented model to the relational database. It means hibernate provides from Java classes to database tables and also provides data querying and retrieval facility.
Transactions
A transaction simply represents a unit of work. In such case, if one step fails, the whole transaction fails (which is termed as atomicity). A transaction can be described by ACID properties (Atomicity, Consistency, Isolation and Durability).
Relationships
Using hibernate, if we want to have relationship between two entities, there must exist a foreign key relationship between the tables, we call it as Referential integrity. The main advantage of having relationship between objects is, we can do operation on one object, and the same operation can transfer onto the…
Entity Lifecycle
In Hibernate, we can either create a new object of an entity and store it into the database, or we can fetch the existing data of an entity from the database. These entity is connected with the lifecycle and each object of entity passes through the various stages of the lifecycle.
Stage 7: Embedded Server
