springMVC的分页简单使用

//首先要导分页的jar包

<dependency>    <groupId>com.github.pagehelper</groupId>    <artifactId>pagehelper</artifactId>    <version>4.0.0</version></dependency>

//然后导入分页需要的pojo类

private int count;    //总条数private int shownum;  //每页最多显示数量private int page;     //当前显示的页数private int sumpage;  //  1/10    page/sumpage

//这里需要自己去封装有参无参

//接下来就是在要查询的方法上添加一些参数了

@RequestMapping("/selectRecordByUId")
        public String selectRecordByUId(HttpSession session,Model model, @RequestParam(value = "PageNum",defaultValue = "1") Integer PageNum, @RequestParam(value = "PageSize",defaultValue = "5") Integer PageSize) {
           User user=(User)session.getAttribute("login");
            PageHelper.startPage(PageNum,PageSize);
            List<Record> list = service.selectRecordByUId(user.getId());
            PageInfo objectPageInfo = new PageInfo(list);
            model.addAttribute("pageInfo", objectPageInfo);
            model.addAttribute("list", list);
            return "jsp/recordList";
        }

//最后就是在界面配置

    <div style="font-weight: bold;font-size: 16px;font-family:'仿宋体';" class="col-md-7">        共<i class="blue">${pageInfo.total}</i>条记录,        当前显示第&nbsp;<i class="blue">${pageInfo.pageNum}/${pageInfo.pages}</i>&nbsp;页    </div>    <nav aria-label="Page navigation">        <ul class="pagination">            <c:if test="${!pageInfo.isFirstPage}">                <li><a href="<%=basePath%>/record/selectRecordByUId.action?PageNum=1">首页</a></li>                <li><a href="<%=basePath%>/record/selectRecordByUId.action?PageNum=${pageInfo.pageNum-1 }"                       aria-label="Previous">                    <span aria-hidden="true">&laquo;</span>                </a>                </li>            </c:if>            <c:forEach items="${pageInfo.navigatepageNums }" var="num">                <c:if test="${num == pageInfo.pageNum }">                    <li class="active"><a href="<%=basePath%>/record/selectRecordByUId.action?PageNum=${num }">${num }</a>                    </li>                </c:if>                <c:if test="${num != pageInfo.pageNum }">                    <li><a href="<%=basePath%>/record/selectRecordByUId.action?PageNum=${num }">${num }</a></li>                </c:if>            </c:forEach>            <c:if test="${!pageInfo.isLastPage}">                <li>                    <a href="<%=basePath%>/record/selectRecordByUId.action?PageNum=${pageInfo.pageNum+1 }"                       aria-label="Next">                        <span aria-hidden="true">&raquo;</span>                    </a>                </li>                <li><a href="<%=basePath%>/record/selectRecordByUId.action?PageNum=${pageInfo.lastPage}">尾页</a></li>            </c:if>        </ul>    </nav></div>
