JRuby からGoogle Drive Data にデータ連携

リアルタイムGoogle Drive 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 Google Drive を使用すると、JRuby からリアルタイムGoogle Drive data へのデータ連携を簡単に実装できます。ここでは、Google Drive 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。

Google Drive 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 Google Drive\lib).

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

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

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

java -jar cdata.jdbc.googledrive.jar

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

Below is a typical JDBC connection string for Google Drive:

jdbc:googledrive:InitiateOAuth=GETANDREFRESH

Google Drive Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: GoogleDriveSelect.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 Google Drive 2018/lib/cdata.jdbc.googledrive.jar' url = "jdbc:googledrive:InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Name, Size FROM Files") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S GoogleDriveSelect.rb

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