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

JDBI でYouTube Analytics 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 YouTube Analytics は、Java アプリケーションとリアルタイムYouTube Analytics 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、YouTube Analytics 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YouTube Analytics 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。

YouTube Analytics Groups 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 MyGroupsDAO { //insert new data into YouTube Analytics @SqlUpdate("INSERT INTO Groups (Mine, ContentDetails_ItemCount) values (:mine, :contentDetails_ItemCount)") void insert(@Bind("mine") String mine, @Bind("contentDetails_ItemCount") String contentDetails_ItemCount); //request specific data from YouTube Analytics (String type is used for simplicity) @SqlQuery("SELECT ContentDetails_ItemCount FROM Groups WHERE Mine = :mine") String findContentDetails_ItemCountByMine(@Bind("mine") String mine); /* * close with no args is used to close the connection */ void close(); }

YouTube Analytics への接続を開く

Collect the necessary connection properties and construct the appropriate JDBC URL for connecting to YouTube Analytics.

YouTube Analytics uses the OAuth authentication standard. You can use the embedded CData OAuth credentials or you can register an application with Google to obtain your own.

In addition to the OAuth values, to access YouTube Analytics data set ChannelId to the Id of a YouTube channel. You can obtain the channel Id in the advanced account settings for your channel. If not specified, the channel of the currently authenticated user will be used.

If you want to generate content owner reports, specify the ContentOwnerId property. This is the Id of the copyright holder for content in YouTube's rights management system. The content owner is the person or organization that claims videos and sets their monetization policy.

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

java -jar cdata.jdbc.youtubeanalytics.jar

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

A connection string for YouTube Analytics will typically look like the following:

jdbc:youtubeanalytics:ContentOwnerId=MyContentOwnerId;ChannelId=MyChannelId;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:youtubeanalytics:ContentOwnerId=MyContentOwnerId;ChannelId=MyChannelId;InitiateOAuth=GETANDREFRESH"); MyGroupsDAO dao = dbi.open(MyGroupsDAO.class); //do stuff with the DAO dao.close();

YouTube Analytics Data について

With the connection open to YouTube Analytics, simply call the previously defined method to retrieve data from the Groups entity in YouTube Analytics.

//disply the result of our 'find' method String contentDetails_ItemCount = dao.findContentDetails_ItemCountByMine("True"); System.out.println(contentDetails_ItemCount);

YouTube Analytics Data の書き方

It is also simple to write data to YouTube Analytics, using the previously defined method.

//add a new entry to the Groups entity dao.insert(newMine, newContentDetails_ItemCount);

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