自定义分页类

之前一直PageHelper分页插件中的PageInfo分页类，但感觉它的属性过多了点，如下：自定义分页类

想着自己写一个，就按着它的源码，照猫画虎的写了一个

private static final long serialVersionUID = 1L;
/**
 * 当前页
 */
private int pageNum;
/**
 * 每页数量
 */
private int pageSize;
/**
 * 当前页数量
 */
private int size;
/**
 * 总页数
 */
private int pages;
/**
 * 总记录数
 */
private long total;
/**
 * 结果集
 */
private List<T> list;

public MyPageInfo(){

}

public MyPageInfo(List<T> list){
    if (list instanceof Page) {
        Page page = (Page)list;
        this.pageNum = page.getPageNum();
        this.pageSize = page.getPageSize();
        this.pages = page.getPages();
        this.list = page;
        this.size = page.size();
        this.total = page.getTotal();
    } else if (list instanceof Collection) {
        this.pageNum = 1;
        this.pageSize = list.size();
        this.pages = 1;
        this.list = list;
        this.size = list.size();
        this.total = (long)list.size();
    }
}

亲测可以结合
