freemarker bootstrap 分页插件总结

<#--
{
     
     
  "totalPage": 0,
  "curPage": 0,
  "size": 0,
  "totalCount": 0,
  "list": [
    {}
  ]
}

-->
<#macro bootstrap_page_1 ID>
        总数: ${pagination.totalPage} |   ${pagination.curPage}
<#if (pagination.totalPage >0)>
<ul class="pagination" id="${ID}">

    <#list 1..pagination.totalPage as page>
        <li ${(pagination.curPage == page)?string("class='active'",'')}><a href="javascript:void(0);" onclick="return false">${page}</a></li>
    </#list>

</ul>
</#if>
</#macro>

后台的 PageUtil

package com.lyr.easymybatis.util;

import com.lyr.easymybatis.pojo.dto.PageInfo;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.ui.Model;

/**
 * @Author lyr
 * @create 2020/12/16 18:01
 */
public class PageUtil {
    
    

    public static <T> void bootstrapPagination(Page<T> page, Model model) {
    
    
        PageInfo<T> x = PageInfo.of(page);
        model.addAttribute("pagination",x);
    }
}

抽象一个统一分页实体，抽象各 持久层框架的细节：
比如 jpa , pageHelper 等

package com.lyr.easymybatis.pojo.dto;

import lombok.Data;
import lombok.experimental.Accessors;
import org.springframework.data.domain.Page;

import java.util.List;

/**
 * @Author lyr
 * @create 2020/12/16 18:16
 */
@Data
@Accessors(chain = true)
public class PageInfo<T> {
    
    

    private Integer totalPage;
    private Integer curPage;
    private Integer size;
    private Long totalCount;

    private List<T> list;

    public static <T> PageInfo<T> of(Page<T> ipage) {
    
    
        PageInfo<T> pageInfo = new PageInfo<>();
        pageInfo.curPage = ipage.getNumber() + 1;
        pageInfo.size = ipage.getSize();
        pageInfo.totalCount = ipage.getTotalElements();
        pageInfo.list = ipage.getContent();
        pageInfo.totalPage = ipage.getTotalPages();
        return pageInfo;
    }

}
