JDBI からStreak Data のデータアクセスオブジェクトを作成

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

Streak Users 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 MyUsersDAO { //request specific data from Streak (String type is used for simplicity) @SqlQuery("SELECT Email FROM Users WHERE Email = :email") String findEmailByEmail(@Bind("email") String email); /* * close with no args is used to close the connection */ void close(); }

Streak への接続を開く

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

Use the following steps to generate a new API key for authenticating to Streak.

  1. Navigate to Gmail
  2. Click on the Streak dropdown to the right of the search bar
  3. Select the Integrations button. This will open a window where you can view existing integrations and create new API keys.
  4. Under the Streak API section of integrations, click the button to Create New Key.


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

java -jar cdata.jdbc.streak.jar

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

A connection string for Streak will typically look like the following:


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:streak:ApiKey=8c84j9b4j54762ce809ej6a782d776j3;"); MyUsersDAO dao =; //do stuff with the DAO dao.close();

Streak Data について

With the connection open to Streak, simply call the previously defined method to retrieve data from the Users entity in Streak.

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

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