//接收用户名和密码，完成对用户的验证
String u=request.getParameter(“username”);
String p=request.getParameter(“passwd”);
//到数据库中验证用户
//1.加载驱动
Class.forName(“com.microsofr.jdbc.sqlserver.SQLServerDriver”);
//2.得到链接
Connection ct=DriverManager.getConnection(“jdbc:microsoft:sqlserver://127.0.0.1:1433;databaseName=ManagementSystem”,”sa”,”HXHhxh1206″);
//3.创建Statement
Statement sm=ct.createStatement();
[color=#000000]这个出现以下问题，已经有导入java.sql.*包了，求解释[/color]
Type mismatch: cannot convert from java.sql.Statement to java.beans.Statement
//4.查询
ResultSet rs=sm.executeQuery(“select passed from admin where username=”””+u+””””);
[color=#000000]可能是上个问题出现，所以导致这个也出现问题，求解释[/color]
Type mismatch: cannot convert from java.sql.Statement to java.beans.Statement
//5.执行，根据结果判断
if(rs.next()){
//说明用户名存在
if(rs.getString(1).equals(p))
{
//一定合法
response.sendRedirect(“wel.jsp?user=”+u);
}else{
//密码错误
response.sendRedirect(“login.jsp”);
