oracle与Java连接方法

Posted 2023-02-26

1.数据源连接，要新建数据源TestDataBase
package com.shenjun;
import java.sql.*;

public class conn

/**
* @param args
*/
public static void main(String[] args)
// TODO Auto-generated method stub
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection ct = DriverManager.getConnection("jdbc:odbc:TestDataBase","scott","tiger");
Statement sm = ct.createStatement();
ResultSet rs = sm.executeQuery("select * from student");
while(rs.next())
System.out.println("用户名："+rs.getString(2));

catch(Exception e)
e.printStackTrace();





2.jdbc连接，引jar包
package com.shenjun;

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

public class conn2

/**
* @param args
*/
public static void main(String[] args)
// TODO Auto-generated method stub
try
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection ct = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:ORCL","scott","tiger");
Statement sm = ct.createStatement();
ResultSet rs = sm.executeQuery("select * from student");
while(rs.next())
System.out.println("用户名："+rs.getString(2));

catch(Exception e)
e.printStackTrace();



参考技术A import java.sql.Connection; import java.sql.DriverManager; import java.这样连接基本上没有什么错误。你可以试试，很可能就是你的oracle服务没有启动
