使用 ORMlite 从任何表中获取数据的通用方法

Question

我正在尝试创建可以使用 ormlite 和 Dao 类从 SQLite 的任何表中获取所有数据的方法，我不知道 Dao 中设置了哪些值，代码如下所示：

public <T> List<T> getAllRecords(Class<T> klass){
    String databaseUrl = "jdbc:sqlite:c:\\Users\\workspace\\my_sqlite";
    SQLiteDBLayer sQLiteDBLayer = new SQLiteDBLayer(SQLiteDBLayer.ConnectionType.READER);
    ConnectionSource connectionSource = null;
    try {
        connectionSource = new JdbcConnectionSource(databaseUrl);
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    Dao<???, String> transfor = null ; //???? is where I'm stuck
    List<T> results;
    try {
        transfor =DaoManager.createDao(connectionSource,????);//And Here also
        results= (List<T>) transfor.queryForAll();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

我解决了：

 Dao<T, String> transfor = null ; //solve 
    List<T> results;
    try {
        transfor =DaoManager.createDao(connectionSource,klass);//Solve
        results= (List<T>) transfor.queryForAll();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
