1、首先创建dto下的分页类PageBean

package com.zzz.blog.dto;import java.util.List;public class PageBean {private Integer pageSize; //页面大小private Integer currentPage; //当前页private Integer totalCount; //总条数private Integer totalPage; //总页数private List list; //每页显示的数据public PageBean(Integer currentPage, Integer totalCount, Integer pageSize) {this.pageSize = pageSize;this.currentPage = currentPage;this.totalCount = totalCount;if(this.currentPage == null) {this.currentPage = 1;}if(this.pageSize == null) {this.pageSize = 5;}//计算总页数this.totalPage = (int) Math.ceil(1.0 * this.totalCount / this.pageSize);//安全if(this.currentPage > this.totalPage) {this.currentPage = this.totalPage;}if(this.currentPage < 1) {this.currentPage = 1;}}//开始的索引，select * from message limit ?,?   开始索引,页面大小public Integer getStart() {return (this.currentPage-1)*this.pageSize;}//get/set
}

2、在查询请求中返回PageBean

	@Autowiredprivate MessageService messageService;@RequestMapping("/findAllMessage") //查找当前页的所有留言public ModelAndView findAllMessage(Integer currentPage,Model model) {//查找当前页所有留言（分页查询）PageBean messagePageBean = messageService.getMessagePageBean(currentPage);//放入model中model.addAttribute("messagePageBean", messagePageBean);return new ModelAndView("/gustbook", "messageModel", model);}

3、实现getMessagePageBean方法和完成jpa的crud接口

package com.zzz.blog.service;import...@Component
public class MessageServiceImpl implements MessageService{@Autowiredprivate MessageRepository messageRepository;...@Override //根据当前页获得当前页数据public PageBean getMessagePageBean(Integer currentPage) {//计算总条数量Integer totalCount = messageRepository.findAllMessageNum();//获得构造pageBeanPageBean pageBean = new PageBean(currentPage, totalCount, 5);//拿到当前页listList<Message> list = messageRepository.getMessagePageList(pageBean.getStart(),pageBean.getPageSize());//赋值给pageBeanpageBean.setList(list);return pageBean;}}

package com.zzz.blog.repository;import ...import com.zzz.blog.domain.Message;public interface MessageRepository extends CrudRepository<Message, Long>{@Query(value="select count(*) from message",nativeQuery = true)Integer findAllMessageNum();@Query(value="select * from message limit ?1,?2",nativeQuery = true)List<Message> getMessagePageList(Integer start, Integer pageSize);}

4、前端接收参数

<!-- 取list里的对象，命名为message，并且遍历list -->
<li th:each="message:${messagePageBean.list}">
...
<img th:src="${message.visitor.image}">
...
</li>
