Custom Validation in Spring Boot best explained – Part 2
This is the 2nd part (the 2nd case example) of how to implement a custom validation in Spring Boot. In this Post we proceed with the implementation of a “master-details” custom validation example, as we’ve mentioned at the beginning.
Custom Validation in Spring Boot best explained – Part 1
In this post, we focus on a common case, when we have to check if a value in a JSON field, passed in the body of a POST request, is one of the values provided in an array we define.
Spring Boot Security Configuration, practically explained – Part3: LDAP Bind Authentication
This is the 3rd in a series of posts which focuses on LDAP Authentication, but does not provide any detail on the LDAP itself. Our aim is to demonstrate how you can implement LDAP Authentication with Spring Boot framework, by using either a configurer (via the the ldapAuthentication()) or an authentication provider Bean (the LdapAuthenticationProvider) in a classic Custom Security Configuration class, extending
the WebSecurityConfigurerAdapter

Quick Intro to Rest API development with Spring Boot
This is a very very simple, yet well-working, Spring Boot REST API project, demonstrating the fundamental building blocks of such a project.

Spring Boot Security Configuration, practically explained – Part1: Starting with Spring Boot Security and Basic HTTP Authentication
The legacy Spring Boot Security Configuration, extending the WebSecurityConfigurerAdapter abstract class, is considered deprecated and is being replaced by a component-based security configuration. However, since the existing coding base is huge, here, we will stick to customization of the WebSecurityConfigurerAdapter, and we will try to provide a better understanding, using practical examples.
