我在servlet项目文件中将jdbc与mysql服务器连接时出现错误[duplicate]

问：

使用 eclipse，我试图在 servlet 程序中与 mysql 连接，但即使我为 mysql 连接器设置了类路径，我也一次又一次地收到相同的错误

this is the error i am getting

这是我试图在eclipse中运行的代码

package in.ineuron.controller;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class Connect
 */
@WebServlet(
        urlPatterns = { "/reg" }, 
        initParams = { 
                @WebInitParam(name = "url", value = "jdbc:mysql://localhost:3306/javasql"), 
                @WebInitParam(name = "user", value = "root"), 
                @WebInitParam(name = "password", value = "password")
        })
public class Connect extends HttpServlet {
    private static final long serialVersionUID = 1L;
    
    public void init() throws ServletException {
        ServletConfig config = getServletConfig();
        String url = config.getInitParameter("url");
        String user = config.getInitParameter("user");
        String password = config.getInitParameter("password");
        
        Connection connection = null;
        try {
            connection = DriverManager.getConnection(url, user, password);
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println(connection);
        
    }

}
