例如: 使用properties載入資料庫配置，獲取資料庫連線connection

在資源根路徑resources下有jdbc.properties檔案

程式碼示例

// 直接傳properties檔名稱，不帶properties字尾
ResourceBundle resourceBundle = ResourceBundle.getBundle("jdbc");
String driver = resourceBundle.getString("jdbc.dirver");
String url = resourceBundle.
 
getString("jdbc.url");
String username = resourceBundle.getString("jdbc.username");
String password = resourceBundle.getString("jdbc.password");
// 使用druid連線池獲取connection連線
DruidDataSource druidDataSource = new DruidDataSource();
druidDataSource.setDriverClassName(driver)
 
;
druidDataSource.setUrl(url);
druidDataSource.setUsername(username);
druidDataSource.setPassword(password);
DruidPooledConnection connection = druidDataSource.getConnection();
System.out.println(connection);
