Repository files navigation

I've written a complete tutorial series for this application on The CalliCoder Blog -

• Part 1: Bootstrapping the Project and creating the basic domain models and repositories

• Part 2: Configuring Spring Security along with JWT authentication and Building Rest APIs for Login and SignUp

• Part 3: Building Rest APIs for creating Polls, voting for a choice in a Poll, retrieving user profile etc

• Part 4: Building the front-end using React and Ant Design

1. Clone the application

   git clone https://github.com/callicoder/spring-security-react-ant-design-polls-app.gitcd polling-app-server

2. Create MySQL database

   create database polling_app

3. Change MySQL username and password as per your MySQL installation

   • opensrc/main/resources/application.properties file.

   • changespring.datasource.username andspring.datasource.password properties as per your mysql installation

4. Run the app

   You can run the spring boot app by typing the following command -

   mvn spring-boot:run

   The server will start on port 8080.

   You can also package the application in the form of ajar file and then run it like so -

   mvn packagejava -jar target/polls-0.0.1-SNAPSHOT.jar

5. Default Roles

   The spring boot app uses role based authorization powered by spring security. To add the default roles in the database, I have added the following sql queries insrc/main/resources/data.sql file. Spring boot will automatically execute this script on startup -

   INSERT IGNORE INTO roles(name)VALUES('ROLE_USER');INSERT IGNORE INTO roles(name)VALUES('ROLE_ADMIN');

   Any new user who signs up to the app is assigned theROLE_USER by default.

First go to thepolling-app-client folder -

cd polling-app-client

Then type the following command to install the dependencies and start the application -

npm install&& npm start

The front-end server will start on port3000.
