Spring Boot Autoconfiguration

Course Content

Spring Boot is an extension of the Spring framework, which eliminates the need for defining each and every configuration which is required for setting up a Spring based application and lets the developer focus on the business logic.

By using Spring Boot Autoconfiguration Spring automatically configures your application based on the dependencies that are present on the classpath. With the Spring Boot Starters you get a kind of shop for all the Spring and releated technologies that you need to start developing Spring based applications. If for example, you want to get started using Spring and JPA for database access you just have to include the spring–boot–starter–data–jpa dependency in your project. In this course I explained the concept of Spring Boot Autoconfiguration and I’ve covered the four most popular and used ContionalOn–xxx annotations:

How to create your own Autoconfiguration Class

What is @ConditionalOnProperty and how to use it

What is @ConditionalOnBean and how to use it

What is @ConditionalOnClass and @ConditionalOnMissingClass and how to use them

What is @ConditionalOnResource and how to use it

Enable the Spring debug mode and analyze the Spring Conditions Evaluation Report

How to create your own ConditionalOn–annotation

Course Project

During this course we will focus on the concept of Spring Boot Autoconfiguration and not on building a complex business logic. We will build and simple Spring application which consists of two RestControllers and two Services and we will use the ContionalOn–xxx annotations in order to controller when these Beans should be created. We will Also enable the debug mode in Spring and analyse the Spring Conditions Evaluation Report in order to understand how evaluates the ConditionOn–xxx Annotations.
