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

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

Acumatica Events 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 MyEventsDAO { //insert new data into Acumatica @SqlUpdate("INSERT INTO Events (Id, location_displayname) values (:id, :location_displayname)") void insert(@Bind("id") String id, @Bind("location_displayname") String location_displayname); //request specific data from Acumatica (String type is used for simplicity) @SqlQuery("SELECT location_displayname FROM Events WHERE Id = :id") String findlocation_displaynameById(@Bind("id") String id); /* * close with no args is used to close the connection */ void close(); }

Acumatica への接続を開く

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

Set the following connection properties to connect to Acumatica:

  • User: Set this to your username.
  • Password: Set this to your password.
  • Company: Set this to your company.
  • Url: Set this to your Acumatica URL, in the format http://{Acumatica ERP instance URL}/entity/{Endpoint name}/{Endpoint version}/.
    For example: https://acumatica.com/entity/Default/17.200.001/

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 Acumatica JDBC Driver.Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.acumatica.jar

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

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

jdbc:acumatica:Url = https://try.acumatica.com/ISV/entity/Default/17.200.001/;User=user;Password=password;Company=CompanyName;

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:acumatica:Url = https://try.acumatica.com/ISV/entity/Default/17.200.001/;User=user;Password=password;Company=CompanyName;"); MyEventsDAO dao = dbi.open(MyEventsDAO.class); //do stuff with the DAO dao.close();

Acumatica Data について

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

//disply the result of our 'find' method String location_displayname = dao.findlocation_displaynameById("1"); System.out.println(location_displayname);

Acumatica Data の書き方

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

//add a new entry to the Events entity dao.insert(newId, newlocation_displayname);

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