UPDATE: We recently released a revision to our Stormpath Spring Security integration. You no longer have to inherit from a special Stormpath security configurer adapter. Instead, you apply a Stormpath DSL (domain specific language). Look below to see how easy this is.

Here at Stormpath, we Spring Boot. It makes it so easy and fun to build rich Java webapps.

We’re very excited for our latest Java SDK release which includes a major overhaul to our Spring Security and Spring Boot support.

If you’ve built a web app before, you know that all the “user stuff” is a royal pain. Stormpath gives developers all that “user stuff” out-of-the-box so you can get on with what you really care about – your app! By the time you’re done with this tutorial ( < 15 minutes, I promise), you’ll have a fully-working Spring Boot webapp that protects user access to restricted paths with Spring Security and is backed by Stormpath.

We’ll focus on our Spring Boot integration to roll out a simple Spring Boot web application example, with a complete user registration and login system. It will have these features:

  • Login and Registration pages
  • Password reset workflows
  • Restricting access according to Group membership
  • The ability to easily enable other Stormpath features in our Java library (API authentication, SSO, social login, and more)

In this demo we will be using the stormpath-default-spring-boot-starter. Its modular design bakes in Spring Boot 1.4.1 and Spring Security 4.1.2 as well as Spring Boot WebMVC and the Thymeleaf templating engine. I will be using my Mac, the Terminal app, and the IntelliJ IDE.

All the code for this tutorial can be found here.

Throughout this post, you can see the example code in action by clicking on the Deploy to Heroku button. All you need to do is register for a free Heroku account.

What Is Stormpath?

Stormpath is an API service that allows developers to create, edit, and securely store
user accounts and user account data, and connect them with one or multiple applications. Our API enables you to:

  • Authenticate and authorize your users
  • Store data about your users
  • Perform password and social based login
  • Send password reset messages
  • Issue API keys for API-based web apps
  • And much more! Check out our Product Documentation

In short: we make user account management a lot easier, more secure, and more
scalable than what you’re probably used to.

Start Your Spring Boot Web App Project

Got your Stormpath developer account? Great! Let’s get started…

Whether you are a Maven maven or Gradle grete, getting your project setup is a snap.

Here’s a pom.xml file to start with:

And, here’s a build.gradle file to start with:

You may notice that both for Maven and Gradle there is a single dependency: stormpath-default-spring-boot-starter. Yup. That’s it. As you will see below, that one dependency gives you all of the Spring Boot, Spring Security and Stormpath magic at once.

Gather Your API Credentials and Application Href

The connection between your app and Stormpath is secured with an “API Key Pair”. You will provide these keys
to your web app and it will use them when it communicates with Stormpath. You can download your API key pair from our Admin Console. After you log in you can download your API key pair from the homepage, it will download the apiKey.properties file – we will use this in a moment.

While you are in the Admin Console you want to get the href for your default Stormpath Application. In Stormpath, an Application object is used to link your web app to your user stores inside Stormpath. All new developer accounts have an app called “My Application”. Click on “Applications” in the Admin Console, then click on “My Application”. On that page you will see the Href for the Application. Copy this — we will need it later.

Note: If you use the Heroku Deploy button below, a Stormpath account will automatically be provisioned and the API Keys will automatically be set for you.

Writing the Spring Boot Application

The code for this section can be found in the LockedDown tag of the code repo. Deploy

We need three small Java classes and an html template to fire up the first version of our webapp. They’re small enough that I will put them right here. Let’s get to it!

Spring Boot Application Entry Point

All Spring Boot applications have an entry point that works just like an ordinary Java program. It has a main method and everything.

Here’s Application.java:

6 lines of code including the @SpringBootApplication annotation kicks off the party.

Spring Security Configuration

By default (and by best security practices), Spring Security locks down your entire application. It locks it down to the point that it’s not even accessible! While this conforms to best security practices, it’s not terribly useful. Additionally, we need to hook Spring Security and Stormpath together. That brings us to our SpringSecurityWebAppConfig.java:

The @Configuration annotation causes Spring Boot to instantiate this class as a configuration. .apply(stormpath()) hooks all of the Stormpath goodness (authentication and authorization workflows) into Spring Security.

Because there is no further configuration in the configure method, we will still see the default behavior of having everything locked down. However, instead of the default Spring Security authentication flows, we will see the default Stormpath flows. That is, attempting to browse to any path in the application will result in a redirect to the Stormpath login page.

So, a 1 line method call and we’ve got security!

Spring WebMVC Ties It All Together

Our security configuration above ensures that all paths in the application will be secured.

In this Spring Boot web app tutorial, we utilize the Controller to determine how requested paths get directed to display which templates.

Here’s our HelloController.java:

The @Controller annotation signals Spring Boot that this is a controller. We have one path defined on line 3, /. Line 5 returns the Thymeleaf template named home.

7 lines of code and we have Model-View-Controller (MVC) routing.

Bring Us home.html

By default, the Thymeleaf templating engine will look for templates returned from controllers in a folder called templates in your classpath. It will also look for the default extension of .html.

So, when our controller above returns "home", Thymeleaf will find the template in resources/templates/home.html.

Let’s take a look at the home.html file:

Line 1 sets up the th namespace for Thymeleaf.

Line 3 looks like an html/xml comment. However, this is a directive that Thymeleaf picks up on to include a fragment in this template. The fragment is found at: resources/templates/fragments/head.html. This fragment contains all the setup to hook in Bootstrap styling for our views.

Lines 13 and 14 is where the action is. Since every pathway in our application is locked down, we know that the only way to get to this page is after having logged in. Part of the Stormpath magic is that once logged in, an account object is always in scope to your views. Line 13 shows the logged in user’s full name. Line 14 provides a link to log out when clicked.

Let’s Fire It Up!

Creating a Stormpath account, 15 lines of Java code and 19 lines of html template code (3 of which are significant) has brought us to the point of a fully functional Spring Boot WebMVC app protected by Spring Security and backed by Stormpath.

If you stored your apiKey.properties file from before in the standard location: ~/.stormpath/apiKey.properties and if you have only the default Stormpath Application that was created for you, no other configuration is necessary to start up the application.

Here’s the Maven way:

Note: The spring-boot-maven-plugin also creates an uber-jar due to the presence of the repackage execution. You can exercise the same code by just running java:

Here’s the Gradle way:

Really? Is that it? Yup!

You can browse to http://localhost:8080/ and see it in action.

Spring Boot Web Application Example

What if you stored your apiKey.properties file somewhere else or you have other Stormpath Applications defined? No Problem!

Remember the Application Href you saved from earlier? We are going to use it now.

Here’s the Maven way:

Here’s the Gradle way:

By adding STORMPATH_API_KEY_FILE and STORMPATH_APPLICATION_HREF environment variables to the command line, we can easily tell our app where to find the api keys and which Stormpath Application to use.

The Stormpath Java SDK has an extremely flexible configuration mechanism. We will see more of that below when we get to restricting access to your application by Stormpath Group membership.

Refined Access Control With Spring Security

The code for this section can be found in the BasicAccessControl tag of the code repo.


In the previous section, we created an application that was locked up tight. Every path, including /, required you to be logged in first.

Perhaps you want a publicly accessible home page. Perhaps you want some parts of the site that any authenticated user can get to and another part of the site where only members belonging to a particular group can get to.

We are going to explore those fine grained controls in this section.

We’ll start by allowing public access to the home page. Users will still have to authenticate to access any another page.

Spring Security: Your Bouncer at the Door

Remember our empty SpringSecurityWebAppConfig.java from before? We are going to add a little something to it now:

Spring Security provides a fluent interface for providing access rules.

On Lines 5 – 8 above, we are building up a rule set for how Spring Security will allow access to our application.

You might state it like this in plain English:

The rules we are specifying take precedence before the default behavior of locking everything down.

Let’s update our home.html template as well:

Notice how we now have two distinct sections. The first starts on line 14 and is displayed if the user is logged in.

The second section starting on line 23 is displayed if the user is not logged in.

This is Thymeleaf templates in action. It provides very powerful controls for conditionally showing parts of a template.

Before we make any additional changes, let’s pause here and startup the app as before.

When you browse to http://localhost:8080, you’ll see the unauthenticated version of the home template.

Unauthenticated Spring Boot Web App

Click the Restricted button, and you’ll be redirected to the login form as expected. After you authenticate, you’ll end up at a 404 page, because we haven’t defined the restricted page yet.

Let’s set that up to finish up this section.

Defining the restricted page is as easy as adding a route in our controller and creating a template to show. Here’s the updated HelloController.java:

And, here’s a new restricted.html template:

Notice how we re-use the head fragment to provide Bootstrap styling for this template.

Re-start the app again, and you will get the full experience. Take note of how the home page changes depending on whether or not you are logged in.

Semi Restricted Spring Boot App Example

Spring Security Access Control By Group Membership

The code for this section can be found in the GroupAccessControl tag of the code repo.


Spring Security provides a set of annotations and a rich expression language for controlling access to methods in your application. Among the most commonly used Spring Security Annotations is @PreAuthorize. And, among the most commonly used SpringEL expressions is hasRole.

Stormpath integrates with this mechanism connecting Stormpath Groups to Spring Security roles.

Let’s look at the code for this and then break it down. We are going to add a new service that restricts access by Group membership. Here’s AdminService:

Line 3 above is the key, here. The annotation along with the SpringEL expression could be stated in plain English as:

The check to see that user is authenticated part of this may not be obvious. What’s going on is that a @PreAuthorize check can only be done on an authenticated user. Spring Security is smart enough to check that the user is logged in before checking to see if they are a member of the specified group.

Let’s dig in to that Spring Expression Language above. Where is Spring Security looking for @roles.ADMIN? The @ symbol is special – it identifies a Java bean. In this case, a bean named roles. Defined inside that bean we expect to find a constant named ADMIN.

Ultimately, hasRole needs to be checking against a unique Href representing a Stormpath Group. So, our ADMIN constant needs to be a Java String that holds the Href to our Stormpath Group used for admin.

To complete this configuration and to make it awesomely dynamic, we need a new class called Roles.java:

These 9 lines are so amazingly powerful, I’m geeking out over here! Let’s dig in.

By annotating this class with @Component on line 1, Spring will instantiate it and expose it as a bean. Guess what the name of the bean is? Spring will take the name of the class and camel-case it to derive the bean name by default. So, the bean name is roles. Sweet!

The @Autowired annotation on line 5 causes Spring Environment object to be passed into the constructor. Inside the constructor, we have our only opportunity to set ADMIN since it’s declared final – a requirement to be able to use it inside the hasRoles clause.

The last piece of the puzzle utilizes some Stormpath configuration magic. Notice that we are setting the value of ADMIN to whatever the environment property named stormpath.authorized.group.admin is set to. This is standard Spring. If you have a property in your application.properties file with this name, it will be available in the Spring Environment.

Stormpath adds the ability to set this as a system environment variable alleviating the need to have the value – a Stormpath Group Href in this case – hardcoded anywhere in your application.

Typically, system environment variables are all caps with words separated by underscores. The Stormpath Java SDK automatically converts these system variables into the lowercase dotted notation.

Dig this:

Behind the scenes, Stormpath will convert the STORMPATH_AUTHORIZED_GROUP_ADMIN system environment variable to a Spring stormpath.authorized.group.admin environment variable. That will get picked up by our code above.

Phew! Who thought such magic could be achieved in so few lines of code!

Now, we need to wire the AdminService to our Controller. Here are the relevant parts of our updated HelloController.java:

AdminService is Autowired in on lines 4 & 5. Notice on line 11, we are calling the adminService.ensureAdmin method. If the logged in user is NOT in the ADMIN group, a 403 (forbidden) response will be generated.

The last bit of code housekeeping to do here is to create an admin.html template. In the code that is associated with this post, there’s a simple admin.html template that shows a nicely formatted message confirming that you are, indeed, an admin.

Now, to see this in action, you’ll need to do a little bit of Stormpath housekeeping in the admin console.

Here are the steps:

  1. Create a new Application

    Spring Boot Web Application Home

    Create Spring Boot Web App

  2. Create a new Group called “admin” for the Application

    Groups Home Example

    Create Group in Spring Boot Web App

  3. Create a new Account in the admin Group

    Accounts Home Example

    Create Account in Spring Boot Web Application

    Accounts Home Example 2

  4. Create a new Account NOT in the admin Group

    Accounts Home Example 3

    Creating Account in Spring Boot Web App

In the code that is associated with this post, I’ve also included a handy error page so that if you are not in the admin group you get a nicely formatted page rather than the default 403 page.

Let’s see it in action. We are going to start up the app as before, only this time we are going to use the Hrefs found in the Admin Console for the new Application and Group you created in the previous step.

Here’s the Maven way:

Here’s the Gradle way:

Browse to the /admin page.

If you log in as the user you created in the Stormpath admin Group ([email protected] in my case), you will have access to the admin page. If you log in as the user you created that’s NOT in the Stormpath admin Group ([email protected] in my case), you will get the forbidden page.

No matter who you log in as, you will have access to the /restricted page as we setup before.

Admin Group Example

Wrapping It Up

Well, we’ve covered a lot of ground here, haven’t we!

We saw how you can protect individual pages as well as protect methods based on membership in a group.

We saw how you can apply Stormpath in your class that extends WebSecurityConfigurerAdapter to define access controls for different paths as well as make use of the Spring Security @PreAuthorize annotation for a finer grain of control.

We saw the almost magical way the Stormpath Java SDK manages environment configuration properties to provide a high degree of flexibility for your application without having to hardcode anything.

There are a lot more features in the Java SDK and the Spring Boot integration. Check out the in-depth tutorial here.
