Once you grant access to Google Drive API, then Google Client library automatically listens to it and saves the access tokens into your project root directory under a folder “tokens”. Access tokens saved automatically in spring boot project If you want to change the port or host in callback URL then you can change it like following: LocalServerReceiver receiver = new LocalServerReceiver.Builder().setHost("127.0.0.1").setPort(8089).build() 7. By default, client library start a jetty server at 8080 port which will listen to the callback when you open the URL in the browser. You need to open this URL in the browser and allow the access at least one time. Using credentials.json file, Google client library creates a URL with callback URL and prints into the console logs of the project.

View and manage metadata of files in your Google Drive. View and manage Google Drive files and folders that you have opened or created with this app. View and manage its own configuration data in your Google Drive. View and manage the files in your Google Drive. Since we need to perform every type of operation in Google Drive, so in our example we will use scope “DRIVE”. You can combine 1 or more scopes together as well. Google Drive has different kinds of permissions which are divided into a few categories, these categories are called scopes.
In the adle file, add all 3 Gradle dependencies for Google Drive client libraries and click the import button. Once project import is complete, under resources directory, add your file “credentials.json”. Open the Spring boot project in any IDE (Intellij Idea is recommended) and import the project as Gradle project. Add Google drive credentials and dependencies in Spring boot project Visit the page for spring boot initializer and create a Gradle project with Java 11. Spring boot Gradle project is recommended for this integration, as it will remove lots of boilerplate code.

Google periodically publishes its dependencies for different programming languages. These libraries also include classes that represent entities for the API context, which are useful for making conversions between Java objects and JSON objects. This generated client libraries include the API-specific information such as root URL along with the core google-API-java-client. To use Google APIs in Java, you would use the generated Java library for the Google APIs.
