javabean层：

        private int pageSize = 10;//每页显示的记录条数
        private int totalRecords;//总记录条数                 Dao可以查出来
        private int startIndex;//每页开始记录的索引号           可以算出来：
        private int startPage;//页码显示：起始页码
        private int endPage;//页码显示：结束页码
        public Page(int pageNum,int totalRecords){
                this.pageNum = pageNum;
