用户信息的bean：

package chen;

public class UserBean
{
private String userid;
private String password;

public void setUserId(String userid)
{
erid=userid;
}
public void setPassword(String password)

{
this.password=password;
}
public String getUserId()
{
return erid;
}
public String getPassword()
{
return this.password;
}

}

提交数据库的bean：

package chen;
import com.mysql.jdbc.Driver;
import java.sql.*;
public class UserRegister
{
private UserBean userBean;
private Connection con;
//获得数据库连接。
public UserRegister()
{

String url="jdbc:mysql://localhost/"+"chao"+"?user="+"root"+"&password="+"850629";

try
{

Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection(url);
}
catch(Exception e)
{
e.printStackTrace();
}

}
//设置待注册的用户信息。
public void setUserBean(UserBean userBean)
{
erBean=userBean;
}
//进行注册
public void regist() throws Exception
{
String reg="insert into userinfo(userid,password) values(?,?)";

try
{
PreparedStatement pstmt=con.prepareStatement(reg);
pstmt.setString(1,userBean.getUserId());
pstmt.setString(2,userBean.getPassword());
pstmt.executeUpdate();
}
catch(Exception e)
{
e.printStackTrace();
throw e;
}

}
}

提交注册数据进入数据库：
