我正在使用JDBC创建网站,运行TOMCAT时出现以下错误,我该怎么办,我在MYSQL工作台中创建了6列,分别为uname,pass,name,city,email,phone,但仍然这个错误。
这是我的register.java servlet文件,我运行它并复制粘贴的类到WEB-INF / classes文件夹中
public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{
response.setContentType("text/html");
PrintWriter out=response.getWriter();
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/form","root","sudhakar");
String uname = request.getParameter("uname");
String psw = request.getParameter("psw");
String nam = request.getParameter("nam");
String cit = request.getParameter("cit");
String ema = request.getParameter("ema");
String num = request.getParameter("num");
PreparedStatement pst = con.prepareStatement("insert into login values(?,?,?,?,?,?)");
pst.setString(1,uname);
pst.setString(2,psw);
pst.setString(3,nam);
pst.setString(4,cit);
pst.setString(5,ema);
pst.setString(6,num);
pst.executeUpdate();
out.print("Successs");
}catch(Exception e){
out.print(e);
}
}
}
将您的SQL语句更改为:
insert into login(uname,pass,name,city,email,phone) values(?,?,?,?,?,?)
