处理JSP页面时发生异常

Question

org.apache.jasper.JasperException: An exception occurred processing JSP page /registration.jsp at line 9

6:     String lname = request.getParameter("lname");
7:     String email = request.getParameter("email");
8:     Class.forName("com.mysql.jdbc.Driver");
9:     Connection con = DriverManager.getConnection("jdbc:mysql://localhost:8080/dbname",
10:             "root", "NEWPASSWORD");
11:     Statement st = con.createStatement();
12:     ResultSet rs;

有人可以帮助我这是我的jsp连接到mysql代码。我不明白这个错误。

Answer 1

我的sql正在端口号 3306

上运行

因此你应该编写如下代码

Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/dbname","root", "NEWPASSWORD");

Answer 2

String lname = request.getParameter("lname");
String email = request.getParameter("email");
Class.forName("com.mysql.jdbc.Driver");

  

Connection con = DriverManager.getConnection（“jdbc：mysql：// localhost：3306 / dbname”，               “root”，“NEWPASSWORD”）;

Statement st = con.createStatement();
ResultSet rs;
