Question

我尝试查看与此问题相关的每个答案，但仍然给我同样的错误。我尝试将jar文件包含到我的项目中，但仍然无法正常工作。请帮我。这是我的servlet文件。

package com.test.testdb;

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

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

/**
 * Servlet implementation class TestDbServlet
 */
@WebServlet("/TestDbServlet")
public class TestDbServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, 
       HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse 
response) throws ServletException, IOException {
        String user = "test";
        String pass = "test";

        String jdbcUrl = "jdbc:mysql://localhost:3306/test? 
   useSSL=false";
        String driver = "com.mysql.jdbc.Driver";

        try {
            PrintWriter out = response.getWriter();
            out.println("Connecting to database: " + jdbcUrl);
            Class.forName(driver);
            Connection myConn = DriverManager.getConnection(jdbcUrl, user, pass);
            out.println("yay");
            myConn.close();
        }
        catch (Exception exc) {
            exc.printStackTrace();
            throw new ServletException(exc);
        }
    }

}

我已经将mysql-connector-java-5.1.47-bin.jar添加到我的WEB-INF> lib文件夹中。我对此并不陌生，所以我仍在尝试解决问题。请帮我。这是我运行文件时得到的。

连接到数据库：jdbc：mysql：localhost：3306 / test java.sql.SQLException：找不到适用于> jdbc：mysql：localhost：3306 / test的合适驱动程序在java.sql.DriverManager.getConnection（未知来源）在java.sql.DriverManager.getConnection（未知来源）在com.hibernate_tutorial.jdbc.Driver.main（Driver.java:16）

eclipse：找不到适用于jdbc的驱动程序
