Create a Data Access Object for Pushbullet Data using JDBI

JDBI is a SQL convenience library for Java that exposes two different style APIs, a fluent style and a SQL object style. The CData JDBC Driver for Pushbullet integrates connectivity to live Pushbullet data in Java applications. By pairing these technologies, you gain simple, programmatic access to Pushbullet data. This article explains how to build a basic Data Access Object (DAO) and the accompanying code to read Pushbullet data.

Create a DAO for the Pushbullet Users Entity

The interface below declares the desired behavior for the SQL object to create a single method for each SQL statement to be implemented.

public interface MyUsersDAO {
  //request specific data from Pushbullet (String type is used for simplicity)
  @SqlQuery("SELECT  FROM Users WHERE  = :")
  String findBy(@Bind("") String );

  /*
   * close with no args is used to close the connection
   */
  void close();
}

Open a Connection to Pushbullet

Collect the necessary connection properties and construct the appropriate JDBC URL for connecting to Pushbullet.

Using API Key Authentication

Pushbullet uses token-based authentication (Access Token). To obtain an Access Token:

1. Log in to your Pushbullet account at https://www.pushbullet.com
2. Navigate to Settings > Account
3. Click "Create Access Token"
4. Copy the generated token

After obtaining your Access Token, set the following connection properties:

• AuthScheme: Set this to APIKey.

• APIKey: Set this to your Pushbullet Access Token.

Example Connection String

Profile=C:\profiles\Pushbullet.apip;ProfileSettings='APIKey=your_access_token;';AuthScheme=APIKey;

Connecting to Pushbullet

Once the authentication is configured, you can connect to Pushbullet and query data from any of the available tables such as Users, Pushes, Devices, Chats, Subscriptions, and Channels.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Pushbullet JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.api.jar

Fill in the connection properties and copy the connection string to the clipboard.

A connection string for Pushbullet will typically look like the following:

jdbc:api:Profile=C:\profiles\Pushbullet.apip;ProfileSettings='APIKey=your_access_token;';AuthScheme=APIKey;

Use the configured JDBC URL to obtain an instance of the DAO interface. The particular method shown below will open a handle bound to the instance, so the instance needs to be closed explicitly to release the handle and the bound JDBC connection.

DBI dbi = new DBI("jdbc:api:Profile=C:\profiles\Pushbullet.apip;ProfileSettings='APIKey=your_access_token;';AuthScheme=APIKey;");
MyUsersDAO dao = dbi.open(MyUsersDAO.class);

//do stuff with the DAO

dao.close();

Read Pushbullet Data

With the connection open to Pushbullet, simply call the previously defined method to retrieve data from the Users entity in Pushbullet.

//disply the result of our 'find' method
String  = dao.findBy("");
System.out.println();

Since the JDBI library is able to work with JDBC connections, you can easily produce a SQL Object API for Pushbullet by integrating with the CData JDBC Driver for Pushbullet. Download a free trial and work with live Pushbullet data in custom Java applications today.
