Ready for Secure Apps!
Let's get a real project ready. You'll spin up a Spring Boot app and pull in the dependencies that switch on Spring Security 6.
Creating a Spring Boot Project
Start fast with Spring Initializr at start.spring.io — a web wizard that generates your whole project structure and build files in seconds.
Initializr Basics
In Spring Initializr you pick the build (Maven), language (Java), a stable Boot version, and metadata like group and artifact. That defines your project skeleton.
What Are Dependencies?
Dependencies are external libraries your app pulls in for features it doesn't write itself — pre-built code you wire in instead of reinventing.
The Security Starter
One dependency unlocks it all: spring-boot-starter-security. This starter pulls in the core auth and authorization modules in a single line.
Web Application Needs
To serve HTTP, add spring-boot-starter-web. It bundles embedded Tomcat and Spring MVC so your app can handle web requests and API responses.
Maven: Your Project's Blueprint
With Maven, you declare every library in pom.xml — your project's blueprint inside a <dependencies> block that tells Maven what to fetch.
Adding Security to pom.xml
Here's how the two starters sit inside your pom.xml dependencies block. Initializr adds these automatically when you select them.
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<!-- Other dependencies like spring-boot-starter-test... -->
</dependencies>First Run: What Happens?
Run the app with the security starter added and Spring Security locks every endpoint instantly. Watch the console for its generated default password.
package com.coddykit.securitysetup;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SecuritysetupApplication {
public static void main(String[] args) {
SpringApplication.run(SecuritysetupApplication.class, args);
System.out.println("\n--- Application Started --- ");
System.out.println("Check your console for a default password if you access the app.");
}
}Quick Check!
After adding spring-boot-starter-security to a new Spring Boot web project, what is the immediate default behavior when you try to access any endpoint in your browser?
Recap: Project Ready!
Recap: you scaffolded a project with Spring Initializr, added the web and security starters, and saw Boot hand you a login page and console password for free.
