分页封装，一切为了极简，做了个util类
package com.moxi.util;

public class PageUtil {

    public static String getPageContent(String url,int pageCurrent,int pageSize,int pageCount){
        if (pageCount == 0) {
            return "";
        }
        String urlNew = url.replace("{pageSize}", pageSize+"").replace("{pageCount}", pageCount+"");

        String first = urlNew.replace("{pageCurrent}", 1+"");
        String prev = urlNew.replace("{pageCurrent}", (pageCurrent - 1)+"");
        String next = urlNew.replace("{pageCurrent}", (pageCurrent + 1)+"");
        String last = urlNew.replace("{pageCurrent}", pageCount+"");

        StringBuffer html = new StringBuffer();
        html.append("<li class="footable-page-arrow"+(pageCurrent<=1?" disabled":"")+""><a href=""+(pageCurrent<=1?"#":first)+"">«</a></li>");
        html.append("<li class="footable-page-arrow"+(pageCurrent<=1?" disabled":"")+""><a href=""+(pageCurrent<=1?"#":prev)+"">‹</a></li>");
        for(int i = 0 ;i < pageCount; i++){
            String urlItem = urlNew.replace("{pageCurrent}", (i+1)+"");
            html.append("<li class="footable-page"+(((i+1) == pageCurrent)?" active":"")+""><a href=""+urlItem+"">"+(i+1)+"</a></li>");
        }
        html.append("<li class="footable-page-arrow"+(pageCurrent==pageCount?" disabled":"")+""><a href=""+(pageCurrent==pageCount?"#":next)+"">›</a></li>");
        html.append("<li class="footable-page-arrow"+(pageCurrent==pageCount?" disabled":"")+""><a href=""+(pageCurrent==pageCount?"#":last)+"">»</a></li>");

        return html.toString().replaceAll("null", "");
    }

}
