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

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

Sage Cloud Accounting SalesInvoices 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 MySalesInvoicesDAO { //insert new data into Sage Cloud Accounting @SqlUpdate("INSERT INTO SalesInvoices (sent, total_amount) values (:sent, :total_amount)") void insert(@Bind("sent") String sent, @Bind("total_amount") String total_amount); //request specific data from Sage Cloud Accounting (String type is used for simplicity) @SqlQuery("SELECT total_amount FROM SalesInvoices WHERE sent = :sent") String findtotal_amountBysent(@Bind("sent") String sent); /* * close with no args is used to close the connection */ void close(); }

Sage Cloud Accounting への接続を開く

Collect the necessary connection properties and construct the appropriate JDBC URL for connecting to Sage Cloud Accounting.

You can connect to Sage Business Cloud Accounting using the embedded OAuth connectivity. When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

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

java -jar cdata.jdbc.sagebcaccounting.jar

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

A connection string for Sage Cloud Accounting will typically look like the following:

jdbc:sagebcaccounting: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:sagebcaccounting:InitiateOAuth=GETANDREFRESH"); MySalesInvoicesDAO dao = dbi.open(MySalesInvoicesDAO.class); //do stuff with the DAO dao.close();

Sage Cloud Accounting Data について

With the connection open to Sage Cloud Accounting, simply call the previously defined method to retrieve data from the SalesInvoices entity in Sage Cloud Accounting.

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

Sage Cloud Accounting Data の書き方

It is also simple to write data to Sage Cloud Accounting, using the previously defined method.

//add a new entry to the SalesInvoices entity dao.insert(newsent, newtotal_amount);

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