使用JDBC-ODBC讀取Excel文件

以下代碼我沒有真正去實踐,緊做為總結,方便以后查閱:

這種方法需要設置ODBC源.....

參考:

附代碼:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
