springboot+jpa分页插件（Pageable+Page）

Pageable+Page实现分页无需配置，也不需要加入jar包（maven依赖）

Controller控制层

package com.gxuwz.late.controller;

import com.gxuwz.late.bean.Record;
import com.gxuwz.late.repository.RecordRepository;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletResponse;

@Controller
@RequestMapping("/manager")
public class ManagerController {
    static Logger logger = LoggerFactory.getLogger(ManagerController.class);

    @Autowired
    RecordRepository recordRepository;

    @RequestMapping("/list")
    public String list(HttpServletResponse response, Model model, Integer pageNum){
                       
        if (pageNum == null){
            pageNum = 1;
        }
        Sort sort = new Sort(Sort.Direction.DESC, "recordNo");  // 这里的"recordNO"是实体类的主键，记住一定要是实体类的字段，而不能是数据库的字段
        Pageable pageable = new PageRequest(pageNum - 1, 6, sort);
        Page<Record> list = recordRepository.findAll(pageable);

        logger.info("pageNum==" + pageNum);

        model.addAttribute("pageInfo", list);

        logger.info("pageInfo=>" + list.getContent().get(0).getClassName());
        response.addHeader("x-frame-options","SAMEORIGIN");  // 允许iframe
        return "record_list";
    }
}

html页面

<table id = "dormitory_table" class="table table-hover text-center">
              <tr>
                <th>晚归记录编号</th>
                <th>宿舍楼编号</th>
                <th>宿舍号</th>
                <th>学号</th>
                <th>班级</th>
                <th>辅导员</th>
                <th>晚归时间</th>
                <th>晚归原因</th>
                <th>操作</th>
              </tr>
                <tr th:each="record:${pageInfo.getContent()}">
                    <td th:text="${record.recordNo }"></td>
                    <td th:text="${record.buildingNo }"></td>
                    <td th:text="${record.dorId }"></td>
                    <td th:text="${record.studentNo }"></td>
                    <td th:text="${record.className }"></td>
                    <td th:text="${record.instName }"></td>
                    <td th:text="${record.time }"></td>
                    <td th:text="${record.reason }"></td>
                </tr>
                  <tr>
                    <td colspan="8">
                        <div class="pagelist">
                            <p>当前<span th:text="${pageInfo.getNumber()} + 1"></span>页,总<span th:text="${pageInfo.totalPages}"></span>页
                            <a th:href="@{/manager/list}">首页</a>
                            <a th:href="@{/manager/list(pageNum = ${pageInfo.hasPrevious()} ? ${pageInfo.getNumber() } : 1)}">上一页</a>
                            <a th:href="@{/manager/list(pageNum = ${pageInfo.hasNext()} ? ${pageInfo.getNumber()} + 2 : ${pageInfo.totalPages})}">下一页</a>
                            <a th:href="@{/manager/list(pageNum = ${pageInfo.totalPages})}">尾页</a></p>
                        </div>

                    </td>
              </tr>
            </table>

实现效果：

jpa用pagehelper的话容易出现问题：如的pageSize无效，分页无效
