JRuby からZoho Books Data にデータ連携

リアルタイムZoho Books data に連携するシンプルなJRuby アプリケーションを作成します。

JRuby はRuby プログラミング言語の高性能で安定した、完全にスレッド化されたJava 実装です。CData JDBC Driver for Zoho Books を使用すると、JRuby からリアルタイムZoho Books data へのデータ連携を簡単に実装できます。ここでは、Zoho Books data に接続し、クエリを実行して結果を表示する簡単なJRuby アプリを作成する方法を説明します。

Zoho Books Data にJDBC で接続

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CDatat\CData JDBC Driver for Zoho Books\lib).

JRuby natively supports JDBC, so you can easily connect to Zoho Books and execute SQL queries.Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

Zoho Books uses the OAuth authentication standard. To authenticate using OAuth, create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Getting Started guide in the Help documentation for an authentication guide.

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

java -jar cdata.jdbc.zohobooks.jar

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

Below is a typical JDBC connection string for Zoho Books:

jdbc:zohobooks:OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;CallbackURL=https://localhost:33333;OrganizationId=MyOrganizationId;InitiateOAuth=GETANDREFRESH

Zoho Books Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: ZohoBooksSelect.rb) and open it in a text editor.Copy the following code into your file:

require 'java' require 'rubygems' require 'C:/Program Files/CData/CData JDBC Driver for Zoho Books 2018/lib/cdata.jdbc.zohobooks.jar' url = "jdbc:zohobooks:OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;CallbackURL=https://localhost:33333;OrganizationId=MyOrganizationId;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT InvoiceId, InvoiceNumber FROM INVOICES") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

With the file completed, you are ready to display your Zoho Books data with JRuby.To do so, simply run your file from the command line:

jruby -S ZohoBooksSelect.rb

Writing SQL-92 queries to Zoho Books allows you to quickly and easily incorporate Zoho Books data into your own JRuby applications.Download a free trial today!
