A brief overview of creating a SQL Object API for Pinterest data in 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 Pinterest integrates connectivity to live Pinterest data in Java applications. By pairing these technologies, you gain simple, programmatic access to Pinterest data. This article walks through building a basic Data Access Object (DAO) and the accompanying code to read Pinterest data.

Create a DAO for the Pinterest 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 Pinterest (String type is used for simplicity) @SqlQuery("SELECT Username FROM Users WHERE FirstName = :firstName") String findUsernameByFirstName(@Bind("firstName") String firstName); /* * close with no args is used to close the connection */ void close(); }

Open a Connection to Pinterest

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

Pinterest authentication is based on the standard OAuth flow. To authenticate, you must initially create an app via the Pinterest developer platform where you can obtain an OAuthClientId, OAuthClientSecret, and CallbackURL.

Set InitiateOAuth to GETANDREFRESH and set OAuthClientId, OAuthClientSecret, and CallbackURL based on the property values for the app you created.

See the Help documentation for other OAuth authentication flows.

Built-in Connection String Designer

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

java -jar cdata.jdbc.pinterest.jar

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

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

jdbc:pinterest:OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='https://localhost:33333'InitiateOAuth=GETANDREFRESH

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:pinterest:OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='https://localhost:33333'InitiateOAuth=GETANDREFRESH"); MyUsersDAO dao = dbi.open(MyUsersDAO.class); //do stuff with the DAO dao.close();

Read Pinterest Data

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

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

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