在jsp中用bean和servlet联合实现用户注册、登录(6)
//System.out.println('\n' + myconn.rs_getHtmlString("name"));
//System.out.println(myconn.rs.getString("name") + myconn.rs_getInt(1));
}
}catch(Exception e){
System.err.println(e.toString());
}
}
}
声明：因为使用的是MySQL数据库，所以需要MySQL数据库的驱动
下载后请将org包放至DBConn.java所在目录下
以确保该bean能正常运行
三、编写用户注册的bean：reg.java
//reg.java
//import required classes
import java.sql.*;
public class reg
{
public int newID = 0;
public boolean result = false;
public boolean reg(String username,String password,String confirm,String email)
{
try{
if(!this.checkUser(username))
return false;
if(!this.checkPwd(password))
return false;
if(!this.verifyPwd(password,confirm))
return false;
if(!this.checkEmail(email))
return false;
if(!this.userNotExit(username))
return false;
this.getNewID();
this.result = this.register(username,password,confirm,email);
return this.result;
}catch(Exception e){
System.out.println(e.toString());
return false;
}
}//End boolean reg
public boolean checkUser(String user)
{
try{
if(user.indexOf("'")!=-1)
{
System.out.println("姓名中含有非法字符！");
return false;
}else
return true;
}catch(Exception e){
System.out.println(e.toString());
return false;
}
}
public boolean checkPwd(String pwd)
{
