JAVA连接HANA数据库

1、在自己电脑配置Java的开发环境（ jdk、tcomcat），在项目中引入ngdbc.jar包,工具包下载地址：

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代码（可询问Basic）

①SAP服务器的地址：事务代码DB02-->配置-->主机-->显示/隐藏 DBCON信息

 

 

②数据库名称：事务代码DB02-->系统配置-->DB User

 

③数据库账号密码（密码在系统一般都是加密的，请问Basic要）：事务代码DB02-->诊断-->数据库用户/权限-->用户输入框的搜索帮助

 

 

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!");
            }
        }
    }


}
