JRuby からXero Data にデータ連携

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

Xero 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 Xero\lib).

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

To connect, set the Schema connection property in addition to any authentication values. Xero offers authentication for private applications, public applications, and partner applications. You will need to set the XeroAppAuthentication property to PUBLIC, PRIVATE, or PARTNER, depending on the type of application configured. To connect from a private application, you will additionally need to set the OAuthAccessToken, OAuthClientId, OAuthClientSecret, CertificateStoreType, CertificateStore, and CertificateStorePassword.

To connect from a public or partner application, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL, or you can register an app to obtain your own OAuth values.

See the "Getting Started" chapter of the help documentation for a guide to authenticating to Xero.

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

java -jar cdata.jdbc.xero.jar

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

Below is a typical JDBC connection string for Xero:

jdbc:xero:InitiateOAuth=GETANDREFRESH

Xero Data への接続性を持つJRuby アプリを作成

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

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

jruby -S XeroSelect.rb

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