- 我已经下载了 mysql-connector-java-5.1.24-bin.jar
- 我
lib
在我的项目中创建了一个文件夹并将 jar 放在那里。 - 项目的属性->构建路径->添加JAR并选择上面的JAR。
- 我仍然得到
java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql
我正在使用 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);
}
}
}
如果我在得到Class.forName("com.mysql.jdbc.Driver");
之前添加Connection connection = DriverManager.getConnection(mySqlUrl, userInfo);
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
