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

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

au Wowma Items 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 MyItemsDAO { //insert new data into au Wowma @SqlUpdate("INSERT INTO Items (ItemCode, Price) values (:itemCode, :price)") void insert(@Bind("itemCode") String itemCode, @Bind("price") String price); //request specific data from au Wowma (String type is used for simplicity) @SqlQuery("SELECT Price FROM Items WHERE ItemCode = :itemCode") String findPriceByItemCode(@Bind("itemCode") String itemCode); /* * close with no args is used to close the connection */ void close(); }

au Wowma への接続を開く

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


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

java -jar cdata.jdbc.wowma.jar

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

A connection string for au Wowma 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:wowma:ApiKey=MyApiKey;ShopId=MyShopId"); MyItemsDAO dao =; //do stuff with the DAO dao.close();

au Wowma Data について

With the connection open to au Wowma, simply call the previously defined method to retrieve data from the Items entity in au Wowma.

//disply the result of our 'find' method String price = dao.findPriceByItemCode("99a87c0x3"); System.out.println(price);

au Wowma Data の書き方

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

//add a new entry to the Items entity dao.insert(newItemCode, newPrice);

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