MySQL Eclipse 프로젝트에 JDBC mysql 드라이버를 추가하는 방법은 무엇입니까?

mysql 5.5를 사용하고 있습니다. 코드:

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);
        }      
    }
}

Connection connection = DriverManager.getConnection (mySqlUrl, userInfo); 앞에 Class.forName ( "com.mysql.jdbc.Driver"); 을 추가하면 가 표시됩니다. java.lang.ClassNotFoundException : com.mysql.jdbc.Driver

 

해결 방법

 

이것을 삽입하십시오 :

DriverManager.registerDriver(new com.mysql.jdbc.Driver());

JDBC 연결을 얻기 전에.
