可以使用以下代码连接Oracle数据库：

<dependency>
    <groupId>com.oracle.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>12.2.0.1</version>
</dependency>

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

public class OracleConnection {
    public static void main(String[] args) {
        Connection conn = null;
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
            String url = "jdbc:oracle:thin:@localhost:1521:ORCL";
            String user = "username";
            String password = "password";
            conn = DriverManager.getConnection(url, user, password);
            System.out.println("Connection successful!");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            try {
                if (conn != null) {
                    conn.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}
