How to enable default Authorization in your Spring Boot Application?

Welcome back friends, Do you know spring boot is by default an unprotected application. i.e. if you develop any Webservice endpoint, it is by default accessible by everybody in the world. that’s why I am saying that Spring Boot is an unprotected application. 

If you want to make your spring boot an authorized application, you have to customize your application using the spring boot Security starter project. Following artifact, you have to add in your Spring Boot Application. It is called a Spring Boot Security starter Project.

Create a simple Simple Project using Please look at below the image for creating a simple Spring Boot Project. According to the below input in the I am creating without Security. It is a simple Web MVC and Rest Application.

Spring Boot

I have imported this simple security project in my IntelliJ and I have written the following endpoint.

public class WelcomeController {

    public String print() {
        return "This is from Spring Boot";

Now I am able to invoke this endpoint by using the following endpoint
Output is…

Spring boot default security

This endpoint I can access without authorization. I want to make this endpoint a protected endpoint using the Spring Boot default security configuration. In order to do that, you have to add the following Artifact in your pom.xml


Once you added this Artifact, restart your Spring Boot Application. You can notice one difference from your Server console log as in the below screenshot.
Spring Security

By adding the Spring boot Security starter Project artifact, we are enabling default Security in our Spring Boot Application. While starting the Application, it generates the default password, when you try to access a Webservice, it never allows you to access. Spring boot throws the default login page and asks you to enter the User name and password. The user name you have to enter “User” and password you have to enter whatever password showing in the Server Console. in our case we need to use the password that highlighted red color in the Server. Let try the demo now.

When I try to hit the following endpoint which we tried before
http://localhost:8080/ Now, I am not able to access this endpoint and it throws the following login form which is spring boot default login form.

Spring Boot login form

In order to access our Webservice endpoint, you need to log in with the following credentials.

User Name = User
password = dd8fd9fa-2279–4f73-be16–98001b186d72 

Each time you restart the server, the new password generates and showed in the Server log and the User name remains the same.
