b.在用户DSN选项卡中点击添加，选择Driver do Microsoft Excel(*.xls)

注册好数据源后就可以写代码了，一个示例如下：

public class ExcelReader {
	private String entry;//ODBC数据源名称
	
	public ExcelReader(String entry) {
		this.entry = entry;
	}
	
	//sheetName为工作表名称
	public String read(String sheetName) throws Exception {
		StringBuilder builder = new StringBuilder();
		Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
		Connection connection = DriverManager.getConnection("jdbc:odbc:" + entry);
		Statement statement = connection.createStatement();
		ResultSet rs = statement.executeQuery("select * from [" + sheetName + "$]");
		while(rs.next()) {
			builder.append(rs.getObject(1));//示意性只读取一列
		}
		rs.close();
		statement.close();
		connection.close();
		return builder.toString();
	}
	
	public static void main(String[] args) throws Exception {
		ExcelReader reader = new ExcelReader("etl");
		System.out.println(reader.read("test"));
	}
}
