使用useBean时中文乱码
文件源代码:

package   com;
import   java.sql.*;
import   db.*;

public   class   newManage
{
ConnDB   con=   new   ConnDB();
private   String   userid,password,qy,username,bm,job,type;

public   void   setUserid(String   u){userid=u;}
public   String   getUserid(){return   userid;}

public   void   setPassword(String   p){password=p;}
public   String   getPassword(){return   password;}

public   void   setQy(String   q){qy=q;}
public   String   getQy(){return   qy;}

public   void   setUsername(String   n){username=n;}
public   String   getUsername(){return   username;}

public   void   setBm(String   b){bm=b;}
public   String   getBm(){return   bm;}

public   void   setJob(String   j){job=j;}
public   String   getJob(){return   job;}

public   void   setType(String   t){type=t;}
public   String   getType(){return   type;}

public   void   updateDatabase(){
Connection   conn=null;
String   userid2,qy2,username2,job2,bm2,type2;
try   {
conn=con.mygetConn();
String   sql= "Insert   Into   Manages(userid,[password],qy,username,job,bm,type)   values(?,?,?,?,?,?,?) ";
PreparedStatement   perstmt=conn.prepareStatement(sql);

userid2   =   new   String(userid.getBytes( "GBK "),   "GBK ");
perstmt.setString(1,userid2);
perstmt.setString(2,password);
perstmt.setString(3,qy);
perstmt.setString(4,username);
perstmt.setString(5,job);
perstmt.setString(6,bm);
perstmt.setString(7,type);
perstmt.executeUpdate();
}catch(Exception   e)   {
e.printStackTrace();
}
}
}


问题   :   userid存入数据库中是乱码?请求帮助,谢谢!

------解决方案--------------------
改为这样：userid2 = new String(userid.getBytes( "ISO-8859-1 "), "GBK ");
