本文整理了Java中cn.hutool.core.bean.BeanUtil
类的一些代码示例,展示了BeanUtil
类的具体用法。这些代码示例主要来源于Github
/Stackoverflow
/Maven
等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。BeanUtil
类的具体详情如下:
包路径:cn.hutool.core.bean.BeanUtil
类名称:BeanUtil
[英]Bean工具类
把一个拥有对属性进行set和get方法的类,我们就可以称之为JavaBean。
[中]豆工具类
把一个拥有对属性进行设置和收到方法的类,我们就可以称之为JavaBean
