from Spring Documentation:
来自 Spring 文档：
Command Object- a JavaBean which will be populated with the data from your forms
Command Object- 一个 JavaBean，它将填充表单中的数据
Think of Command Objectas a POJO/JavaBean/etc.. that backs the form in your presentation layer.
将其Command Object视为支持表示层中的表单的 POJO/JavaBean/等。
Once the form is submitted, all the individual attributes are mapped/bound to this object. On the way up to presentation, Command Objectproperties may be used to pre/populate the form.
提交表单后，所有单独的属性都映射/绑定到此对象。在进行演示的过程中，Command Object可以使用属性来预/填充表单。
