1、在自己電腦配置Java的開發環境（ jdk、tcomcat），在專案中引入ngdbc.jar包,工具包下載地址：

https://mvnrepository.com/artifact/com.sap.cloud.db.jdbc/ngdbc

https://repo1.maven.org/maven2/com/sap/cloud/db/jdbc/ngdbc/2.5.52/

2、Java程式碼（可參考SAP HANA Studio的連線方式或者詢問Basis要SAP伺服器的地址、埠、賬號、密碼）

package com.test;

import java.sql.
 
*;

public class JDBCDemoHANA {
    
    public static String connectionString = "jdbc:sap://192.168.xxx.xx:30xxx";
    public static String user = "IT001";
    public static String password = "xxx";

    public static void main(String[] args) {
        Connection connection = null;
        try {
            connection 
 
= DriverManager.getConnection(connectionString, user, password);
        } catch (SQLException e) {
            System.err.println("Connection Failed. User/Passwd Error? Message: " + e.getMessage());
            return;
        }
        if (connection != null) {
            try {
                System.out.println(
 
"Connection to HANA successful!");
                Statement stmt = connection.createStatement();
                ResultSet resultSet = stmt.executeQuery("SELECT MATNR FROM SAPABAP1.MARA");
                while(resultSet.next()) {
                    String matnr = resultSet.getString(1);
                    System.out.println(matnr);
                }
            } catch (SQLException e) {
                System.err.println("Query failed!");
            }
        }
    }


}
