Spring Security Framework Practical Project Hands-on Part.1

This course is Part 1 of a series designed to teach you how to apply the Spring Security framework to real-world projects step-by-step. Rather than just explaining simple theories, you will directly implement features based on an actual TodoApp project, such as saving Writer information to the database, setting up method-level authentication and authorization, and restricting post registration on template pages. Additionally, you will learn how to implement password rules and complex validation logic used in practice by utilizing the @Pattern regular expression (intermediate) from the Validation library. The course explains the parts students find most difficult—"the difference between authentication and authorization," "understanding DB integration structures," and "how to apply method security"—in an easy-to-understand manner by following the actual code flow. The curriculum is focused on building practical application skills through a structured approach of Theory → Code Modification → Testing → Result Verification.
