    java.sql.SQLException: No value specified for parameter 1 代码如下 public boolean login(UserInfo user)throws Exception{ //用户登录 boolean flag=false; int userNo=Integer.parseInt(user.getUserNo()); String password=user.getPassword(); //测试是否从现在的user对象中取到了值 System.out.println(userNo+"我是USER对象的userNo"); System.out.println(password+"我是USER对象的password"); DatabaseConnection dbc=new DatabaseConnection();//取得数据库连接和关闭对象; try{ String sql="SELECT userNo FROM userInfo where userNo= and password= "; this.conn=dbc.getConnection(); this.pst=conn.prepareStatement(sql); //this.pst.setInt(1, userNo);//给sql中参数赋值 this.pst.setLong(1, userNo); this.pst.setString(2, password); ResultSet rs=pst.executeQuery(); if(rs.next()){//传入用户账号和对应的密码都存在时为真 flag=true; System.out.println(rs.getString(userNo)+"我是从数据库里取出来的"); System.out.print(flag+"测试flag");//测试flag,看是否进入了if里面,true则进入了 rs.close(); } }catch(Exception e){ e.printStackTrace(); }finally{ if(this.pst!=null){ this.pst.close(); } this.conn.close(); } return flag; } 报的错误信息如:
