Question

我已经安装了oracle并在其中创建了表。现在我想将intellij想法连接到oracle。我已将classes12.jar添加到库中，但我无法将代码连接到oracle。我该怎么办？我的代码是：

package example;

import java.sql.*;
public class first {
    private Connection connection;
    private Statement statement;
    public first()throws Exception
    {
        Class.forName("oracle.jdbc.driver.oracleDriver");
        connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ORCL","maryam","myjava123");
        statement = connection.createStatement();
    }

    public void insert() throws Exception
    {
        statement.executeUpdate("INSERT INTO T1 (ID,NAME) VALUES (1,'ALI')");

    }
    public void close() throws Exception
    {
        statement.close();
        connection.close();
    }

    public static void main(String[] args)throws Exception {
        first mari=new first();
        mari.insert();
    }
}

，错误是：

Exception in thread "main" java.lang.ClassNotFoundException: oracle.jdbc.driver.oracleDriver

Answer 1

更改

Class.forName("oracle.jdbc.driver.oracleDriver");
//--------------------------------^-- here is the issue

到

Class.forName("oracle.jdbc.OracleDriver");

或

Class.forName("oracle.jdbc.driver.OracleDriver");

此外，检查驱动程序jar文件是否确实存在于类路径中。

Answer 2

在classpath中使用ojdbc6.jar或ojdbc7.jar。并且还将oracleDriver更改为OracleDriver。
