JDBI からMicrosoft OneDrive Data のデータアクセスオブジェクトを作成

JDBI でMicrosoft OneDrive data 用のSQL オブジェクトAPIを作成する方法を概説します。

JDBI は、Fluent スタイルとSQL オブジェクトスタイルという2つの異なるスタイルAPI を公開する、Java 用のSQL コンビニエンスライブラリです。CData JDBC Driver for Microsoft OneDrive は、Java アプリケーションとリアルタイムMicrosoft OneDrive data のデータ連携を実現します。これらの技術を組み合わせることによって、Microsoft OneDrive data へのシンプルなコードアクセスが可能になります。ここでは、基本的なDAO(Data Access Object )とそれに付随するMicrosoft OneDrive data の読み書きのためのコードの作成について説明します。

Microsoft OneDrive Files Entity のDAO を作成

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 MyFilesDAO { //request specific data from Microsoft OneDrive (String type is used for simplicity) @SqlQuery("SELECT Name FROM Files WHERE Id = :id") String findNameById(@Bind("id") String id); /* * close with no args is used to close the connection */ void close(); }

Microsoft OneDrive への接続を開く

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

OneDrive uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Help documentation for an authentication guide.

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

java -jar cdata.jdbc.onedrive.jar

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

A connection string for Microsoft OneDrive will typically look like the following:

jdbc:onedrive:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;OAuthCallbackURL=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:onedrive:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;OAuthCallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH"); MyFilesDAO dao = dbi.open(MyFilesDAO.class); //do stuff with the DAO dao.close();

Microsoft OneDrive Data について

With the connection open to Microsoft OneDrive, simply call the previously defined method to retrieve data from the Files entity in Microsoft OneDrive.

//disply the result of our 'find' method String name = dao.findNameById("Jq74mCczmFXk1tC10GB"); System.out.println(name);

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