gmailApiClient

Explore the seamless integration of Gmail within a Spring Boot framework with this application, designed to offer secure and efficient email management. Harnessing OAuth2 for robust authentication, it provides a user-friendly platform to read, compose, and organize emails, making it an ideal solution for both personal and professional email interactions powered by Gmail's extensive capabilities.

Getting Started with the Gmail API

Setting Up Google Services

1. Create a Project in Google Cloud Console:

   • Navigate to the Google Cloud Console.
   • Create a new project.
   • Note: Remember the Project ID as it will be used later.

2. Enable the Gmail API:

   • In the Google Cloud Console, navigate to "APIs & Services" > "Dashboard."
   • Click "+ ENABLE APIS AND SERVICES" and search for "Gmail API."
   • Enable the Gmail API for your project.

3. Create Credentials:

   • Go to "APIs & Services" > "Credentials."
   • Click "Create Credentials" and select "OAuth client ID."
   • Set up the OAuth consent screen if prompted.
   • Choose "Web application" as the Application type.
   • Add the necessary redirect URIs (e.g., http://localhost:8080/login/oauth2/code/google for local testing).
   • Note: Keep the Client ID and Client Secret secure.

Configuring Application Credentials

To integrate the Gmail API with your Spring Boot application, you need to configure your Google credentials in the application.yaml file. This allows your application to authenticate with Google services securely.

1. Locate or Create Your application.yaml:

   • Find the application.yaml file in your Spring Boot project's src/main/resources directory.
   • If the file doesn't exist, create it in the aforementioned directory.

2. Add Google Credentials:

   • Open application.yaml and add the following lines, replacing YOUR_CLIENT_ID and YOUR_CLIENT_SECRET with your actual Google OAuth 2.0 credentials:

   google:
     client-id: YOUR_CLIENT_ID
     client-secret: YOUR_CLIENT_SECRET

3. Referencing Credentials in the Application:

   • In your Spring Boot application, reference these credentials using the @Value annotation or through configuration properties binding.
   • Example for using @Value:

   @Value("${google.client-id}")
   private String googleClientId;
   
   @Value("${google.client-secret}")
   private String googleClientSecret;

4. Securing the Credentials:

   • Important: Do not commit the application.yaml file with real credentials to public repositories. Consider using environment variables or external configuration management for sensitive data.

Setting Up Spring Boot Application

1. Initialize a Spring Boot Project:

   • Use Spring Initializr to bootstrap a new Spring Boot project.
   • Choose the necessary dependencies (e.g., Spring Web etc) and add it to build.gradle file.

2. Clone/Download the Project:

   • git clone
   • Or download the ZIP file and extract it.

3. Open and Run the Project:

   • Open the project in your preferred IDE.
   • Run the application (usually by running the main method in the YourApplication.java file).
