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

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

Salesforce Chatter Users 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 MyUsersDAO { //request specific data from Salesforce Chatter (String type is used for simplicity) @SqlQuery("SELECT PostCount FROM Users WHERE SearchTerms = :searchTerms") String findPostCountBySearchTerms(@Bind("searchTerms") String searchTerms); /* * close with no args is used to close the connection */ void close(); }

Salesforce Chatter への接続を開く

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

Salesforce Chatter uses OAuth 2.0 authentication. To authenticate to Salesforce Chatter via OAuth 2.0, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with Salesforce Chatter.

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

java -jar cdata.jdbc.salesforcechatter.jar

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

A connection string for Salesforce Chatter will typically look like the following:

jdbc:salesforcechatter:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:343343;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:salesforcechatter:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:343343;InitiateOAuth=GETANDREFRESH"); MyUsersDAO dao = dbi.open(MyUsersDAO.class); //do stuff with the DAO dao.close();

Salesforce Chatter Data について

With the connection open to Salesforce Chatter, simply call the previously defined method to retrieve data from the Users entity in Salesforce Chatter.

//disply the result of our 'find' method String postCount = dao.findPostCountBySearchTerms("Smoked*BBQ"); System.out.println(postCount);

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