JSP标签分页实现(2)

        Object p = pageContext.getRequest().getAttribute( 
                value); 
        PageBean pageBean = (PageBean) pageContext.getRequest().getAttribute(value); 
         
        StringBuffer sb = new StringBuffer(); 
         
        if (pageBean != null && pageBean.getItems() != null 
                && pageBean.getItems().size() > 0) { 
 
            sb.append("共" + pageBean.getCurPage() + " / " 
                    + pageBean.getPageNum() + "页"); 
            //首页 上一页 
            if (pageBean.getCurPage() > 1) { 
                sb.append("<a href='?page=1'>首页</a>"); 
                sb.append("<a href='?page=" + (pageBean.getCurPage()-1) + "'>上一页</a>"); 
            } 
             
            //循环显示中间页码，这里也可控制最大只显示多少页码 
            for (int i = 1; i < pageBean.getPageNum() + 1; i++) { 
 
                if (i == pageBean.getCurPage()) { 
                    sb.append(" " + i + " "); 
                } else { 
                    sb.append("<a href='?page=" + i + "'> " + i + " </a>"); 
                }
