使用DriverManager类设置jdbc拦截器

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

public class MyInterceptor implements java.sql.Driver {
    private final java.sql.Driver driver;

    public MyInterceptor(java.sql.Driver driver) {
        this.driver = driver;
    }

    @Override
    public Connection connect(String url, Properties info) throws SQLException {
        // 在连接之前可以添加额外的逻辑
        System.out.println("Connecting to database: " + url);
        return driver.connect(url, info);
    }

    // 其他方法的实现...

    public static void main(String[] args) throws SQLException {
        // 加载数据库驱动程序
        Class.forName("com.mysql.jdbc.Driver");

        // 注册驱动程序
        java.sql.Driver driver = DriverManager.getDriver("jdbc:mysql://localhost:3306/mydb");

        // 创建拦截器类
        MyInterceptor interceptor = new MyInterceptor(driver);

        // 设置拦截器
        DriverManager.registerDriver(interceptor);

        // 使用拦截器创建连接
        Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb", "username", "password");

        // 执行SQL语句...

        // 关闭连接
        connection.close();
    }
}
