用户信息列表

//定义分也会用到的四个分页

int pageSize=3;

int pageNow=1; //默认显示第一页

int rowCount=0;

int pageCount=0;//通过pageSize和rowCount得到的

//查询得到rowCount

//1.加载驱动

Class.forName("com.mysql.jdbc.Driver");

//2.得到连接

Connection ct=DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/test","root","198673");

//3.创建Statment

Statement sm=ct.createStatement();

//4.查询

ResultSet rs=sm.executeQuery("select count(*) from users ");

//必须要rs.next(),否则痛不欲生

if(rs.next())

{

rowCount=rs.getInt(1);

}

//计算pageCount

if(rowCount%pageSize==0)

{

pageCount=rowCount/pageSize;

}else{

pageCount=rowCount/pageSize+1;

}

//查询需要显示的记录,注意是在mysql中

rs=sm.executeQuery("select passwd from users limit"+(pageNow-1)*pageSize+","+pageSize);

//显示
