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

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

WooCommerce Orders 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 MyOrdersDAO { //insert new data into WooCommerce @SqlUpdate("INSERT INTO Orders (ParentId, Total) values (:parentId, :total)") void insert(@Bind("parentId") String parentId, @Bind("total") String total); //request specific data from WooCommerce (String type is used for simplicity) @SqlQuery("SELECT Total FROM Orders WHERE ParentId = :parentId") String findTotalByParentId(@Bind("parentId") String parentId); /* * close with no args is used to close the connection */ void close(); }

WooCommerce への接続を開く

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

WooCommerce supports the following authentication methods: one-legged OAuth1.0 Authentication and standard OAuth2.0 Authentication.

Connecting using one-legged OAuth 1.0 Authentication

Specify the following properties (NOTE: the below credentials are generated from WooCommerce settings page and should not be confused with the credentials generated by using WordPress OAuth2.0 plugin):

  • ConsumerKey
  • ConsumerSecret

Connecting using WordPress OAuth 2.0 Authentication

After having configured the plugin, you may connect to WooCommerce by providing the following connection properties:

  • OAuthClientId
  • OAuthClientSecret
  • CallbackURL
  • InitiateOAuth - Set this to either GETANDREFRESH or REFRESH

In either case, you will need to set the Url property to the URL of the WooCommerce instance.

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

java -jar cdata.jdbc.woocommerce.jar

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

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

jdbc:woocommerce:Url=https://example.com/; ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad; ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5; 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:woocommerce:Url=https://example.com/; ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad; ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5; InitiateOAuth=GETANDREFRESH"); MyOrdersDAO dao = dbi.open(MyOrdersDAO.class); //do stuff with the DAO dao.close();

WooCommerce Data について

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

//disply the result of our 'find' method String total = dao.findTotalByParentId("3"); System.out.println(total);

WooCommerce Data の書き方

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

//add a new entry to the Orders entity dao.insert(newParentId, newTotal);

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