Spring Security Framework Practical Project Part.2 – Advanced Validation & Update/Delete Implementation

Hello, this is ITGO. This course is Part 2 of the Spring Security Framework Practical Project series, focusing on essential features required in actual project environments. The areas that students find most challenging in practice are as follows: - Lack of understanding of advanced Regular Expression (Regex) syntax - Confusion on how to apply Validation @Pattern - Lack of understanding regarding the overall flow of Update and Delete functions - Errors in author-based access control and @PreAuthorize settings - Difficulty in distinguishing roles between Controller and Service In this course, rather than simple theoretical explanations, we help students clearly understand "why it must be implemented this way" through: ✔ Actual code implementation ✔ Testing ✔ Analysis of error scenarios ✔ Step-by-step hands-on practice We will implement login authentication and user-specific access control by integrating Spring Security with a database, and complete the Update & Delete functions based on a TodoApp project. The learning focuses on structures and designs that can be applied immediately in the field.
