Spring Boot Login Page Example

This project is a simple login page implemented using Spring Boot. Below are some key details about the project:

Database

The login page utilizes a PostgreSQL database for storing user credentials and other relevant information.

Spring Boot Starter Security

The login form is created using spring-boot-starter-security, which provides robust authentication and authorization features out of the box.

Spring Boot Version

This project is built with Spring Boot version 3.2.3.

Authorization

Access to Home page2 is restricted to users with the ROLE_ADMIN privilege.

Before Running the Project

Before running this project, make sure you complete the following steps:

1. Enter database name, username and password in "application.properties" file.

2. In your database create the following table

CREATE TABLE usert (id int primary key,
				   username varchar(100),
				   password varchar(100),
				   role varchar(100));

3. In your database insert the user details

INSERT INTO usert (id, username, password, role) values 
	(1, 'user1', '$2a$10$Rd0QuZhnLMVBzmJRkm3vNujZiTzUBhmxh0Rdd0XAPoMyb10K5YwmG', 'ROLE_USER'),	--password = pass1
	(2, 'user2', '$2a$10$FzdzNyXJIn1nRIKXRLLWmOmmSFLBdvMQgaMO6kdPHpvg94Vth0H52', 'ROLE_USER'),	--password = pass2
	(3, 'admin', '$2a$10$z303SZBL1330WhDyuMvltuA/Q0OlK6Bc4wdWRqewvIoX0JksYvCWq', 'ROLE_ADMIN'); --password = pass3

The passwords are encoded using the Bcrypt hashing method.

You can use a tool like (https://www.browserling.com/tools/bcrypt) to generate bcrypt hashes for passwords.

For example, for the password pass1 with 10 rounds, the bcrypt hash is $2a$10$Rd0QuZhnLMVBzmJRkm3vNujZiTzUBhmxh0Rdd0XAPoMyb10K5YwmG.
