Jsp实现的简单用户管理系统(注册界面)

我的数据库用的是mysql，名字是db_01,账号和密码都是root

1.Register.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>

<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
%>  
  
  
    
      
      
    
      
      
          
      
      
      
      
    
  
  
     
    <%@include file="title.jsp" %> 
    
  
    注册界面

    <%@include file="footer.jsp" %>
      
    
 

2.RegisterCheck.jsp

  <%@ page language="java" import="java.util.*,java.sql.*" pageEncoding="utf-8"%>  

<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
%>  
  
  
  
    
      
      
      
      
      
      
          
      
      
      
  
    
    
    <%        
            String user = new String(request.getParameter("username").getBytes("ISO-8859-1"),"UTF-8");    
            String pwd = request.getParameter("password");  
  
            String driverClass = "com.mysql.jdbc.Driver";  
            String url = "jdbc:mysql://localhost:3306/db_01";  
            String username = "root";  
            String password = "root";  
            Class.forName(driverClass);//加载驱动   
            Connection conn = DriverManager.getConnection(url,username,password);//得到连接  
            PreparedStatement pStmt = conn.prepareStatement("select * from user where usr = '" + user + "'");  
              ResultSet rs = pStmt.executeQuery();  
                if(rs.next()){  
                    out.println("");  
                }else{  
                    PreparedStatement tmt = conn.prepareStatement("Insert into user values('" + user + "','" + pwd + "',null,null,null,null,null,null,null,null,null,null,null)");  
                        int rst = tmt.executeUpdate();  
                        if (rst != 0){  
                              out.println("");    
                        }else{  
                           out.println("");    
                        }  
                }  
     %>
