springboot+jpa分页（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 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";
    }
}
