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

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

Blackbaud FE NXT Accounts 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 MyAccountsDAO { //insert new data into Blackbaud FE NXT @SqlUpdate("INSERT INTO Accounts (ModifiedBy, AccountNumber) values (:modifiedBy, :accountNumber)") void insert(@Bind("modifiedBy") String modifiedBy, @Bind("accountNumber") String accountNumber); //request specific data from Blackbaud FE NXT (String type is used for simplicity) @SqlQuery("SELECT AccountNumber FROM Accounts WHERE ModifiedBy = :modifiedBy") String findAccountNumberByModifiedBy(@Bind("modifiedBy") String modifiedBy); /* * close with no args is used to close the connection */ void close(); }

Blackbaud FE NXT への接続を開く

Collect the necessary connection properties and construct the appropriate JDBC URL for connecting to Blackbaud FE NXT.

Blackbaud Financial Edge NXT uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.

See the Getting Started guide in the CData driver documentation for more information.

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

java -jar cdata.jdbc.financialedgenxt.jar

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

A connection string for Blackbaud FE NXT will typically look like the following:

jdbc:financialedgenxt:SubscriptionKey=MySubscriptionKey;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:financialedgenxt:SubscriptionKey=MySubscriptionKey;InitiateOAuth=GETANDREFRESH"); MyAccountsDAO dao = dbi.open(MyAccountsDAO.class); //do stuff with the DAO dao.close();

Blackbaud FE NXT Data について

With the connection open to Blackbaud FE NXT, simply call the previously defined method to retrieve data from the Accounts entity in Blackbaud FE NXT.

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

Blackbaud FE NXT Data の書き方

It is also simple to write data to Blackbaud FE NXT, using the previously defined method.

//add a new entry to the Accounts entity dao.insert(newModifiedBy, newAccountNumber);

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