我使用的是MysqL 5.5
代码：

package DBTest;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.sql.*;
import java.util.*;

/**
 * Servlet implementation class TenUsers
 */
@WebServlet("/TenUsers")
public class TenUsers extends HttpServlet {
    /**
     * @see HttpServlet#doGet(HttpServletRequest request,HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException {

        PrintWriter out = response.getWriter();
        String MysqLUrl = "jdbc:MysqL://localhost:3306/MysqL";

        Properties userInfo = new Properties();
        userInfo.put("user","root");
        userInfo.put("password","SabababArba");
        try{
            Connection connection = DriverManager.getConnection(MysqLUrl,userInfo);
        }catch(Exception e) {
            out.println(e);
        }      
    }
}

如果我添加Class.forName(“com.MysqL.jdbc.Driver”);之前连接连接= DriverManager.getConnection(MysqLUrl,userInfo);我得到java.lang.ClassNotFoundException：com.MysqL.jdbc.Driver
