Create a Data Access Object for Stripe 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 Stripe integrates connectivity to live Stripe data in Java applications. By pairing these technologies, you gain simple, programmatic access to Stripe data. This article explains how to build a basic Data Access Object (DAO) and the accompanying code to read and write Stripe data.

Create a DAO for the Stripe Customers 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 MyCustomersDAO {
 //insert new data into Stripe
 @SqlUpdate("INSERT INTO Customers (Delinquent, Discount) values (:delinquent, :discount)")
 void insert(@Bind("delinquent") String delinquent, @Bind("discount") String discount);

 //request specific data from Stripe (String type is used for simplicity)
 @SqlQuery("SELECT Discount FROM Customers WHERE Delinquent = :delinquent")
 String findDiscountByDelinquent(@Bind("delinquent") String delinquent);

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

Open a Connection to Stripe

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

Use the OAuth authentication standard to connect to Stripe. To authenticate using OAuth, register an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Built-in Connection String Designer

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

java -jar cdata.jdbc.stripe.jar

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

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

jdbc:stripe:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://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:stripe:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;");
MyCustomersDAO dao = dbi.open(MyCustomersDAO.class);

//do stuff with the DAO

dao.close();

Read Stripe Data

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

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

Write Stripe Data

It is also simple to write data to Stripe, using the previously defined method.

//add a new entry to the Customers entity
dao.insert(newDelinquent, newDiscount);

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