How to Install Spring Security in Spring Boot (Without Breaking Everything)
Ever wanted to protect your Java app like it’s guarding the last donut in the office? 🍩 In this video, Deividas Strole shows you how to install Spring Security in your Spring Boot application and secure your admin endpoints, while keeping public endpoints open for everyone else.
🎯 What You'll Learn:
Add Spring Security to your Spring Boot project safely
Lock down /admin/** endpoints like Fort Knox 🔐
Keep /api/articles/** publicly accessible 📖
Create an in-memory admin login (username: admin, password: adminpass)
Test protected endpoints from Postman or React
Use Basic Auth without running into CORS issues
🛠️ Quick Setup Steps:
Add Spring Security to your Maven project: spring-boot-starter-security
Create a SecurityConfig class:
/admin/** requires login
/api/articles/** is public
Other endpoints allowed as needed
Add an in-memory admin user:
Username: admin
Password: adminpass (use bcrypt encoding!)
Role: ADMIN
Test your endpoints:
Public GET /api/articles/titles works without login
Protected POST /admin/articles returns 401 unless logged in
Send Authorization header from React using Basic base64(admin:adminpass)
💡 Perfect For:
Java developers securing Spring Boot applications
Full-stack developers integrating React with Spring Boot backends
Anyone learning Spring Security and Basic Authentication
Developers looking to protect admin endpoints while keeping public APIs open
