Let’s create a step-by-step spring boot project and add spring security to the application
Create spring boot project
There are many different ways to create a spring boot application, you can follow the below articles to create one –
>> Create spring boot application using Spring initializer
>> Create spring boot application in Spring tool suite [STS]
>> Create spring boot application in IntelliJ IDEA
Add maven dependencies
Open pom.xml and add the following dependencies –
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

spring-boot-starter-web dependency for building web applications using Spring MVC. It uses the tomcat as the default embedded container. spring-boot-starter-security dependency, which will help to implement spring security.
Change the username and password
Spring Security also provides an option to change the default username and password with the help of the application.properties file
spring.security.user.name=b2tech
spring.security.user.password=b2tech
inside the properties file, we are adding our own username and password to access the URIs instead of the one provided by spring security. By adding these two properties, now we have customized the username and password of the spring security framework.
Once we added these two properties, spring-security will no longer generate the password inside the console when we run the app.
Create a Rest controller
Create HomeController.java inside the in.bushansirgur.springboot.controller package and add the following content
package in.bushansirgur.springboot.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HomeController {
@GetMapping("/home")
public String showHomePage () {
return "Showing the home page contents";
}
}
We have created a handler method showHomePage() that are mapped to the URI /home, which will return a static text.
Run the app
Run the application using the below maven command –
mvn spring-boot:runOpen the browser and enter the following URL –
http://localhost:8080/home
Once we enter the correct username and password which we added in the properties file, it returns the response.
