JSP页面的分页逻辑及代码，采用EL表达式

<!-- start 分页 -->
	<div class="modw_page">
		<a href="${basePath}/user/infoList.do?page=1"><span id="firtPage">首页</span></a>
		<!-- 上一页 -->
		<c:choose>
			<c:when test="${page.pageNo != 1}">
			 	<a href="${basePath}/user/infoList.do?page=${page.pageNo-1}"><span id="prePage">上一页</span></a> 
			</c:when>
			<c:otherwise>
			 	<a href="#"><span>上一页</span></a>
			</c:otherwise>
		</c:choose>
		  
		<!-- 页数列表 
		   1.总页数不足6页-> begin=1, end=总页数
		   2.通过公式设置begin=当前页-3，end=当前页+3
		   3.开始也小于1从新赋值begin=1，end=6
		   4.结束页大于总页数，从新赋值begin=${page.totalPage-5}，end=${page.totalPage}
		 -->
                <c:choose>
			<c:when test="${page.totalPage <= 6}">
				<!-- 1.总页数不足6页-> begin=1, end=总页数 -->
			 	<c:set var="begin" value ="1" />
        		<c:set var="end" value ="${page.totalPage}" />
			</c:when>
			<c:otherwise>
				<!-- 2.通过公式设置begin=当前页-3，end=当前页+3 -->
			 	<c:set var="begin" value ="${page.pageNo-3}" />
        		<c:set var="end" value ="${page.pageNo+3}" />
        		<!-- 3.开始也小于1从新赋值begin=1，end=6 --> 
        		<c:if test="${begin < 1}">
        			<c:set var="begin" value="1"/>
             		<c:set var="end" value="6"/>
        		</c:if>
        		<!-- 4.结束页大于总页数，从新赋值begin=${page.totalPage-5}，end=${page.totalPage} -->
	            <c:if test="${end > page.totalPage}">
	                 <c:set var="begin" value="${page.totalPage-5}"/>
	                 <c:set var="end" value="${page.totalPage}"/>
	            </c:if> 
			</c:otherwise>
		</c:choose>
        
        <!-- 5.获取到begin和end的值循环 -->
	   <c:forEach begin="${begin}" end="${end}" var="i">
	     <c:choose>
	           <c:when test="${i eq page.pageNo}">
	              <span class="lsit_sty">${i}</span>
	           </c:when>
	           <c:otherwise>
	              <a href="${basePath}/user/infoList.do?page=${i}"><span>${i}</span></a>
	           </c:otherwise>
	     </c:choose>
	   </c:forEach>  
	   
	  <!-- 6.显示点点点 
      <c:if test="${end < page.totalPage}">
            <span>...</span>
      </c:if> -->  
         
	  <!-- 下一页 -->   
	  <c:choose> 
		 <c:when test="${page.pageNo != page.totalPage}">
			 <a href="${basePath}/user/infoList.do?page=${page.pageNo+1}"><span id="nextPage">下一页</span></a>
		 </c:when>
		 <c:otherwise> 
			 <a href="#"><span>下一页</span></a> 
		 </c:otherwise>
	  </c:choose>
		
	  <!-- 末页 --> 
	  <a href="${basePath}/user/infoList.do?page=${page.totalPage}"><span id="lastPage">末页</span></a>
	  
	  <!-- 跳转页 -->
	  <span>共${page.totalPage}页,</span>到第
	  <input type="text" value="${page.pageNo}" id="input_go" onkeyup="chenkPage()" class="modwp_input"> 页  
	  <input type="button" value="确认" onclick="checkGo('${basePath}')" id="btn_dis" class="modwp_subt">

	<!-- end分页 -->
