处理JSP页面出现异常

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是在端口号上运行

因此，你应该写你的代码如下

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"); 

连接CON =的DriverManager.getConnection（“JDBC：MySQL的： // localhost：3306/dbname“， ”root“，”NEWPASSWORD“）;

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