Spring Security : Getting started with Spring Security and Spring Boot

Points To Remember

  • Add dependency of spring security
  • Add custom username password in application.properties
  • A unique password is generated each time application is started if no authentication process is specified.
  • You can configure your own authentication  providers, managers, filters, entry points, tokens etc as required.

Getting started with Spring Security and Spring Boot

In order to apply Spring Security to a Spring Boot application, firstly you need to add the dependency in the application as follows

  • In Maven you can do it as follows.
  • In Gradle you can do it as follows.
    dependencies {
        compile 'org.springframework.security:spring-security-web:4.0.3.RELEASE'
Your initial project may look like as shown in the image

Create a controller HomeController as in out case and just add a /home mapping for the application.

package com.ekiras.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

 * Created by ekansh on 18/11/15.
@RequestMapping(value = "/")
public class HomeController {

    @RequestMapping(value = "home")
    public String home(){
        return "Hello World";

Now, just run the application using command

gradle run

Now open the application in browser, you will get a popup to enter the user name and password. This is the default security provided by spring security.

You can login using the default

  • username - user
  • password - generated at application startup as shown in image below

Note : A unique password is generated each time the application is started.

You can also create a custom username and password by specifying it in the application.properties as follows


Now you can login with the credentials

  • username - ekansh
  • password - password
