1101学习记录！！！一定切记，executeUpdate后面括号中不要添加strSql

package com.company;import java.sql.*;/** * Created by ttc on 16-11-1. */public class Insert{    public static void insertUser(UserInfo ui) throws ClassNotFoundException, SQLException    {        Connection con = DbUtils.getConnection();        String strSql = "INSERT INTO userinfo VALUES (seq_userinfo.nextval,?,?)";        PreparedStatement ps = con.prepareStatement(strSql);        ps.setString(1,ui.getUsername());        ps.setString(2,ui.getUserpass());        ps.executeUpdate();        DbUtils.close(con,ps);    }}
