类名称：JsonNode
方法名：deepCopy

JsonNode.deepCopy介绍

[英]Method that can be called to get a node that is guaranteed not to allow changing of this node through mutators on this node or any of its children. This means it can either make a copy of this node (and all mutable children and grand children nodes), or node itself if it is immutable.

Note: return type is guaranteed to have same type as the node method is called on; which is why method is declared with local generic type.
[中]方法，该方法可被调用以获取一个节点，该节点保证不允许通过此节点或其任何子节点上的变异器更改此节点。这意味着它可以创建此节点（以及所有可变子节点和大子节点）的副本，也可以创建不可变的节点本身。
注意：返回类型保证与调用节点方法的类型相同；这就是为什么方法是用局部泛型类型声明的。
