如何使用pagebean进行查询及翻页

Question

package com.lhkj.util.beans;public class Page {
    private int pagesize;
    private int startnum;
    
    public Page(int startnum,int size){
        this.startnum=startnum;
        this.pagesize=size;
    }
    public int getPagesize() {
        return pagesize;
    }
    public void setPagesize(int pagesize) {
        this.pagesize = pagesize;
    }
    public int getStartnum() {
        return startnum;
    }
    public void setStartnum(int startnum) {
        this.startnum = startnum;
    }
}
action里面 // 从页面获得偏移量
                Integer pagesize=30;
                
                session.setAttribute("pagesize", pagesize);
                
                // 从页面获得偏移量
                String offset = request.getParameter("pager.offset");                if (offset == null) {
                    // 第一次查询,需要查出记录总数
                    String count = "";
                    count = this.technologyStoreService
                            .findTechByisAuditSharePageNum(2).toString();
                    // 只需要下传页面总记录数，每页记录数即可。
                    session.setAttribute("resultSize", count);
                }                if (offset == null || offset.equals("")) {
                    offset = "0";
                }
                int intoffset = 0;
                if (offset != null && !offset.equals("")) {
                    intoffset = Integer.parseInt(offset);
                }                final Page page = new Page(intoffset, pagesize);
                session.setAttribute("pagesize", pagesize);
                // 查询处索要的list
                List tmp = this.technologyStoreService
                        .findTechByisAuditSharePage(2, page);
                session.setAttribute("slist", tmp);
jsp里面 <pg:pager items="${sessionScope.resultSizeDetail }"
                                                                maxPageItems="${requestScope.pagesizeDetail}"
                                                                maxIndexPages="<%=10%>" isOffset="<%=true%>"
                                                                url="/lhkjywgl/technologyStore/addTechnologyStore.do"
                                                                export="offset,currentPageNumber=pageNumber"
                                                                scope="request">
                                                                <pg:param name="operate" value="detail"></pg:param>
                                                                <pg:param name="technologyStore1"
                                                                    value="${technologyStore1}"></pg:param>
                                                                <pg:param name="recopyId" value="${recopyId}"></pg:param>
                                                                <pg:param name="recopyIdd" value="${recopyIdd}"></pg:param>
                                                                <pg:param name="id" value="${id}"></pg:param>
                                                                <pg:param name="op" value="op"></pg:param>
                                                                <pg:param name="niming" value="0"></pg:param>
                                                                <jsp:include page="/plugins/paging/jsp/altavista.jsp"
                                                                    flush="true" />
                                                                <!-- 从page对象中取得属性值firstItem , lastIterm -->
                                                                <pg:page export="firstItem, lastItem">
                                                                    <font color="red">本页 <strong><%=firstItem%>
                                                                    </strong> -- <strong> <%=lastItem%> </strong>条 <strong>/</strong>
                                                                        总记录数 <strong><bean:write name="resultSizeDetail" />
                                                                    </strong>条 </font>
                                                                </pg:page>
                                                            </pg:pager>楼主参考！
