JRuby からSalesforce Data にデータ連携

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

Salesforce 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 Salesforce\lib).

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

There are several authentication methods available for connecting to Salesforce: Login, OAuth, and SSO. The Login method requires you to have the username, password, and security token of the user.

If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication.

SSO (single sign-on) can be used by setting the SSOProperties, SSOLoginUrl, and TokenUrl connection properties, which allow you to authenticate to an identity provider. See the "Getting Started" chapter in the help documentation for more information.

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

java -jar cdata.jdbc.salesforce.jar

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

Below is a typical JDBC connection string for Salesforce:

jdbc:salesforce:User=username;Password=password;SecurityToken=Your_Security_Token;

Salesforce Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: SalesforceSelect.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 Salesforce 2018/lib/cdata.jdbc.salesforce.jar' url = "jdbc:salesforce:User=username;Password=password;SecurityToken=Your_Security_Token;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Industry, AnnualRevenue FROM Account") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S SalesforceSelect.rb

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