1. Java + Maven 配置连接Oracle数据库

添加maven依赖

 <dependency>
      <groupId>com.oracle.database.jdbc</groupId>
      <artifactId>ojdbc8</artifactId>
      <version>21.5.0.0</version>
 </dependency>

建立数据库连接

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

public class Connector 

    public static Connection getOracleConnection() throws ClassNotFoundException, SQLException 
        Class.forName("oracle.jdbc.driver.OracleDriver"); // 加载数据库驱动
        String url = "jdbc:oracle:thin:@172.1.0.0:1521:orcl"; // 连接URL
        String username = "admin";
        String password = "123456";
        Connection connection = DriverManager.getConnection(url, username, password);
        return connection;
