基于freemark，ssm和Oracle实现的分页功能

freemark页面`<#list mesgList as mesg>

${mesg.msgNo}&lt;/button&gt;&lt;/td&gt; &lt;td&gt;${mesg.msgName}
${mesg.msgSerl}&lt;/td&gt; &lt;td&gt;${mesg.orgMsgSerl}
${mesg.comSerl}&lt;/td&gt; &lt;td&gt;${mesg.comSerlRef}
${mesg.transType}&lt;/td&gt; &lt;td&gt;${mesg.transTypeStr}
${mesg.sendDate}&lt;/td&gt; &lt;td&gt;${mesg.msgStateName}

    </tr>
    </#list>
    <div >	    

<#if page.totalCount !=0>
第 ${page.current}页/共${page.end}页

controller层

@RequestMapping("/list")
	public String list(ModelMap map, Model model, HttpServletRequest request) {
		String scheme = request.getScheme();
		String serverName = request.getServerName();
		int port = request.getServerPort();
		String path = request.getContextPath();
		String basePath = scheme + "://" + serverName + ":" + port + path;
		System.out.println(basePath);
		request.setAttribute("basePath", basePath);
		long msgState = -1;
		String msgType = request.getParameter("msgtype");
		String queryMsgNo = request.getParameter("queryMsgNo");
		//sang
				int pageNum=3;
				if (request.getParameter("pageNum") != null&&!"".equals(request.getParameter("pageNum"))){
					pageNum = Integer.parseInt(request.getParameter("pageNum"));
				}
			

		if (request.getParameter("msgState") != null && !"".equals(request.getParameter("msgState"))) {
			msgState = Long.parseLong(request.getParameter("msgState"));
		}

		//Map<String, Object> param = new HashMap<String, Object>();
		MesgQueryVo vo=new MesgQueryVo();

				}

				mesgList.get(i).setTransTypeStr(getTransTypeStr(String.valueOf(mesgList.get(i).getTransType())));
			}
		}
       map.addAttribute("page", page);
		map.addAttribute("mesgList", mesgList);

	}

service实现方法

public Page findByPage(MesgQueryVo vo) {
		int numPerPage=vo.getNumPerPage();
		int pageNum=vo.getPageNum();
		Page page = new Page();
		page.setNumPerPage(numPerPage);
		page.setCurrent(pageNum);
		
		int totalCount = userMapper.getItemsCount(vo);
		page.setTotalCount(totalCount);//设置总记录数
		if(totalCount%numPerPage!=0){
			page.setEnd(totalCount/numPerPage+1);
		}else{
			page.setEnd(totalCount/numPerPage);
		}
		if(page.getEnd()<3){
			page.setCurrent(1);
			vo.setPageNum(1);
		}
				
		int start = (pageNum - 1)*numPerPage;
		List list = userMapper.findByPage(vo);
		page.setMesgs(list);//设置当前页面数据 
		
		return page;
	}

mapper层

<select id="findByPage"  resultType="mock.model.Mesg" parameterType="mock.constant.MesgQueryVo">
	select * from(select rownum rm,s.COM_SERL as comSerl,
	s.MSG_SERL as msgSerl,
	s.COM_SERL_REF as comSerlRef,
	s.ORG_MSG_SERL as orgMsgSerl,
	s.MSG_NO as msgNo,
	s.TRANS_TYPE as transType,
	to_char(s.SEND_DATE,'yyyy-mm-dd HH24:MI:SS') as sendDate,
	s.MESSAGE_STATUS as msgState
	from CPEC_MIDDLE_REQ_MSG s
	where
	s.STATUS =1
	<if test="msgtype != null and msgtype !='' ">
	and s.MSG_NO like '%'||#{msgtype}||'%'
	</if>
	<if test="msgState != -1 ">
	and s.MESSAGE_STATUS= #{msgState}
	</if>
	<if test="queryMsgNo !=null and queryMsgNo !='' ">
	and s.MSG_SERL like '%'||#{queryMsgNo}||'%'
	</if>
	order by s.INPUT_TIME desc) where rm&gt;(${pageNum}-1)*${numPerPage} and rm&lt;=${pageNum}*${numPerPage}
	</select>

突然意识到当前页和每页数·可以在page类中指定

package mock.model;

import java.util.List;

public class Page {
	private int current=3;//��ǰҳ
	private int end;//βҳ
	private int numPerPage=15;//ÿҳ��¼��
	private int totalCount;//�ܼ�¼��
	private List<Mesg> Mesgs;//��ǰҳ���� 
	public int getCurrent() {
		return current;
	}
	public void setCurrent(int current) {
		this.current = current;
	}
	public int getEnd() {
		return end;
	}
	public void setEnd(int end) {
		this.end = end;
	}
	public int getNumPerPage() {
		return numPerPage;
	}
	public void setNumPerPage(int numPerPage) {
		this.numPerPage = numPerPage;
	}
	public int getTotalCount() {
		return totalCount;
	}
	public void setTotalCount(int totalCount) {
		this.totalCount = totalCount;
	}
	public List<Mesg> getMesgs() {
		return Mesgs;
	}
	public void setMesgs(List<Mesg> mesgs) {
		Mesgs = mesgs;
	}
	@Override
	public String toString() {
		return "Page [current=" + current + ", end=" + end + ", numPerPage=" + numPerPage + ", totalCount=" + totalCount
				+ ", Mesgs=" + Mesgs + "]";
	}
	
	
}

freemark中的上一页下一页可以用c:if标签控制是否显示
