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

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

SurveyMonkey MySurvey_Responses 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 MyMySurvey_ResponsesDAO { //insert new data into SurveyMonkey @SqlUpdate("INSERT INTO MySurvey_Responses (ChoiceText, ChoiceId) values (:choiceText, :choiceId)") void insert(@Bind("choiceText") String choiceText, @Bind("choiceId") String choiceId); //request specific data from SurveyMonkey (String type is used for simplicity) @SqlQuery("SELECT ChoiceId FROM MySurvey_Responses WHERE ChoiceText = :choiceText") String findChoiceIdByChoiceText(@Bind("choiceText") String choiceText); /* * close with no args is used to close the connection */ void close(); }

SurveyMonkey への接続を開く

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

SurveyMonkey uses the OAuth 2 authentication standard. See the Getting Started section in the help documentation for a guide.

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

java -jar cdata.jdbc.surveymonkey.jar

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

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

jdbc:surveymonkey:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;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:surveymonkey:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;InitiateOAuth=GETANDREFRESH"); MyMySurvey_ResponsesDAO dao = dbi.open(MyMySurvey_ResponsesDAO.class); //do stuff with the DAO dao.close();

SurveyMonkey Data について

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

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

SurveyMonkey Data の書き方

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

//add a new entry to the MySurvey_Responses entity dao.insert(newChoiceText, newChoiceId);

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