BeanQuery 是一个把对象转换为Map的Java工具库。支持选择Bean中的一些属性，对结果进行排序和按照条件查询。不仅仅可以作用于顶层对象，也可以作用于子对象。

BeanQuery的使用非常简单也很直接，例子代码如下：

/静态导入BeanQuery
import static cn.jimmyshi.beanquery.BeanQuery.*;


//使用 select、from、where、orderBy、desc和asc来组装一个Query，然后执行execute方法来获得结果。
List<>> result = select(price,name,mainAuthor.name as mainAuthorName)
    .from(bookCollection)
    .where(
        //for books name is Book2 or starts with Book1
        anyOf(
            value(name, startsWith(Book1)),
            value(name, is(Book2))
        ),
        //for books price between (53,65)
        allOf(
            value(price, greaterThan(53d)),
            value(price,lessThan(65d))
        )
    )
    .orderBy(name).desc()
    .execute();
