This example app shows how to build a Photo Gallery with Spring Boot, React, and JHipster.
Please read Build a Photo Gallery PWA with React, Spring Boot, and JHipster to see how this app was created. You can also watch a screencast on YouTube.
Prerequisites: Java 8, Node.js, and Yarn.
Okta has Authentication and User Management APIs that reduce development time with instant-on, scalable user infrastructure. Okta’s intuitive API and expert support make it easy for developers to authenticate, manage, and secure users and roles in any application.
To install this example application, run the following commands:
git clone https://github.com/oktadeveloper/okta-react-photo-gallery-example.git photo-gallery
cd photo-gallery
This will get a copy of the project installed locally. To install all of its dependencies and start the app, run the commands below.
yarn
yarn webpack:build
./mvnw
To log in to your app, you’ll need to have Keycloak up and running. JHipster ships with a Docker container that has the default users and roles. Start Keycloak using the following command.
docker-compose -f src/main/docker/keycloak.yml up
The security settings in src/main/resources/config/application.yml
are configured for this image.
security:
basic:
enabled: false
oauth2:
client:
accessTokenUri: http://localhost:9080/auth/realms/jhipster/protocol/openid-connect/token
userAuthorizationUri: http://localhost:9080/auth/realms/jhipster/protocol/openid-connect/auth
clientId: web_app
clientSecret: web_app
scope: openid profile email
resource:
userInfoUri: http://localhost:9080/auth/realms/jhipster/protocol/openid-connect/userinfo
To use Okta, you’ll need to change a few things. First, you’ll need to create a free developer account at https://developer.okta.com/signup/. After doing so, you’ll get your own Okta domain, that has a name like https://dev-123456.oktapreview.com
.
Modify src/main/resources/application.yml
to use your Okta settings.
security:
basic:
enabled: false
oauth2:
client:
accessTokenUri: https://{yourOktaDomain}/oauth2/default/v1/token
userAuthorizationUri: https://{yourOktaDomain}/oauth2/default/v1/authorize
clientId: {clientId}
clientSecret: {clientSecret}
scope: openid profile email
resource:
userInfoUri: https://{yourOktaDomain}/oauth2/default/v1/userinfo
Create an OIDC App in Okta to get a {clientId}
and {clientSecret}
. To do this, log in to your Okta Developer account and navigate to Applications > Add Application. Click Web and click the Next button. Give the app a name you’ll remember, specify http://localhost:8080
as a Base URI, and http://localhost:8080/login
as a Login Redirect URI. Click Done and copy the client ID and secret into your application.yml
file.
Create a ROLE_ADMIN
and ROLE_USER
group and add users into them. Create a user (e.g., “admin@jhipster.org” with password “Java is hip in 2018!”). Modify e2e tests to use this account when running integration tests. You’ll need to change credentials in src/test/javascript/e2e/account/account.spec.ts
and src/test/javascript/e2e/admin/administration.spec.ts
.
Navigate to API > Authorization Servers, click the Authorization Servers tab and edit the default one. Click the Claims tab and Add Claim. Name it “roles”, and include it in the ID Token. Set the value type to “Groups” and set the filter to be a Regex of .*
.
After making these changes, you should be good to go!
This example uses the following open source libraries:
Please post any questions as comments on the blog post, or visit our Okta Developer Forums. You can also email developers@okta.com if would like to create a support ticket.

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.
Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

As an extension of the Spring Framework, Spring Boot is widely used to make development on Spring faster, more efficient and convenient. In this article, we will look at some of the parameters were using Spring Boot can drastically reduce the time and effort required in application development.

In this tutorial, we will learn how to build a full stack React Redux + Spring Boot example with a CRUD App. The back-end server uses Spring Boot with Spring Web MVC for REST APIs and Spring Data JPA for interacting with embedded database (H2 database). Front-end side is made with React, Redux, React Router, Axios & Bootstrap.

The images below shows screenshots of our System.
On this Page, you can:
You can also find the Spring Restful Apis that works with other databases here:
- Spring JPA + PostgreSQL
- Spring JPA + MySQL
- Spring Data + MongoDB
Methods | Urls | Actions |
---|---|---|
POST | /api/tutorials | create new Tutorial |
GET | /api/tutorials | retrieve all Tutorials |
GET | /api/tutorials/:id | retrieve a Tutorial by :id |
PUT | /api/tutorials/:id | update a Tutorial by :id |
DELETE | /api/tutorials/:id | delete a Tutorial by :id |
DELETE | /api/tutorials | delete all Tutorials |
GET | /api/tutorials?title=[keyword] | find all Tutorials which title contains keyword |
JpaRepository
.
- The database will be H2 Database (in memory or on disk) by configuring project dependency & datasource.
– Tutorial
data model class corresponds to entity and table tutorials.
– TutorialRepository
is an interface that extends JpaRepository for CRUD methods and custom finder methods. It will be autowired in TutorialController
.
– TutorialController
is a RestController which has request mapping methods for RESTful requests such as: getAllTutorials, createTutorial, updateTutorial, deleteTutorial, findByPublished…
– Configuration for Spring Datasource, JPA & Hibernate in application.properties.
– pom.xml contains dependencies for Spring Boot and H2 Database.
– The App
component is a container with React Router
. It has navbar
that links to routes paths.
– Three components that dispatch actions to Redux Thunk Middleware
which uses TutorialDataService
to call Rest API.
TutorialsList
component gets and displays Tutorials.Tutorial
component has form for editing Tutorial's details based on :id
.AddTutorial
component has form for submission new Tutorial.– TutorialDataService
uses axios
to make HTTP requests and receive responses.
This diagram shows how Redux elements work in our React Application:
We’re gonna create Redux store
for storing tutorials
data. Other React Components will work with the Store via dispatching an action
.
The reducer
will take the action and return new state
.
react
, react-router-dom
, react-redux
, redux
, redux-thunk
, axios
& bootstrap
.App
is the container that has Router
& navbar.TutorialsList
, Tutorial
, AddTutorial
.TutorialDataService
has methods for sending HTTP requests to the Apis.About Redux elements that we’re gonna use:
