    • Build and Deploy the Project 

    mvn clean install

    This is a Spring Boot project, so you can deploy it by simply using the main class: Application.java
    

    Set up MySQL
    

    mysql -u root -p 
> CREATE USER 'tutorialuser'@'localhost' IDENTIFIED BY 'tutorialmy5ql';
> GRANT ALL PRIVILEGES ON *.* TO 'tutorialuser'@'localhost';
> FLUSH PRIVILEGES;

    Set up Email
    

    You need to configure the email by renaming file "email.properties.sample" to "email.properties" and provide your own username and password.
    
You also need to use your own host, you can use Amazon or Google for example.
    
You may also setup an email server locally.  See "email.properties.localhost.sample" for more details.
