PageHelper分页总数不正确解决
<h5>PageHelper单表简单查询没有问题，复杂查询总数和页数不正确</h5>
<h5>自定义PageInfo:</h5>
<pre><code>package com.yiding.saas.ydsaas.common.core;
import com.github.pagehelper.Page;
import com.github.pagehelper.PageInfo;
/**
* 重写pageInfo
* 解决pageInfo total pages错误问题
*/
public class CustPageInfo {
private PageInfo pageInfo;
private Page page;
public CustPageInfo(com.github.pagehelper.PageInfo pageInfo, Page page) {
pageInfo.setPages(page.getPages());
pageInfo.setTotal(page.getTotal());
this.pageInfo = pageInfo;
this.page = page;
}
public PageInfo getPageInfo() {
return pageInfo;
}
}
</code></pre>
<h5>使用：</h5>
<pre><code>Page<Object> page = PageHelper.startPage(ydDeviceDto.getPageNum(), ydDeviceDto.getPageSize());
PageInfo<JSONObject> pageInfo = new PageInfo<>(jsonObjects);
pageInfo=new CustPageInfo(pageInfo,page).getPageInfo();</code></pre>
