【分页查询3】DatatableResultBean类，用来封装PageInfo对象，返回给前端_pageinfo 可以包进另外一个对象返回给前端吗?-优快云博客

本文介绍如何在后端通过DatatableResultBean类来封装PageInfo对象，以便更方便地将分页查询结果返回给前端。示例中展示了创建DatatableResultBean对象并设置相关属性，包括分页信息和数据列表。

给前端返回DatatableResultBean对象，用DatatableResultBean类来封装PageInfo对象**：**
示例：
PageInfo pageInfo =new PageInfo(assembleResultVOS);
return new DatatableResultBean(pageInfo);

DatatableResultBean类：

public class DatatableResultBean
implements Serializable {
private static final long serialVersionUID = -1L;
private Meta meta;
private List data = new ArrayList();
private Map<String,String> titles;
private List lists = new ArrayList();
public DatatableResultBean(){}
public DatatableResultBean(PageInfo pageInfo) {
this.meta = new Meta();
this.meta.setPage(pageInfo.getPageNum());
this.meta.setPages(pageInfo.getPages());
this.meta.setPerpage(pageInfo.getPageSize());
this.meta.setTotal(pageInfo.getTotal());
this.data = pageInfo.getList();
}
public DatatableResultBean(PageInfo pageInfo,List lists) {
this.meta = new Meta();
this.meta.setPage(pageInfo.getPageNum());
this.meta.setPages(pageInfo.getPages());
this.meta.setPerpage(pageInfo.getPageSize());
this.meta.setTotal(pageInfo.getTotal());
this.data = pageInfo.getList();
this.lists = lists;
}
public E converDataEntity(Class clazz) {
return JSON.parseObject(JSON.toJSONString(this.data, new SerializerFeature[]{SerializerFeature.WriteNonStringValueAsString}), clazz);
}

public JSONObject converDataJSONObject() {
    return JSON.parseObject(JSON.toJSONString(this.data, new SerializerFeature[]{SerializerFeature.WriteNonStringValueAsString}));
}

public <E> List<E> converDataArray(Class<E> clazz) {
    return JSON.parseArray(JSON.toJSONString(this.data, new SerializerFeature[]{SerializerFeature.WriteNonStringValueAsString}), clazz);
}

public JSONArray converDataJSONArray() {
    return JSON.parseArray(JSON.toJSONString(this.data, new SerializerFeature[]{SerializerFeature.WriteNonStringValueAsString}));
}

public Meta getMeta() {
    return this.meta;
}

public void setMeta(Meta meta) {
    this.meta = meta;
}

public List getData() {
    return this.data;
}

public void setData(List data) {
    this.data = data;
}

public Map<String, String> getTitles() {
    return titles;
}

public void setTitles(Map<String, String> titles) {
    this.titles = titles;
}

public List getLists() {
    return lists;
}

public void setLists(List lists) {
    this.lists = lists;
}

}
