Java: Static transient fields
提问by python dude
I just found out in Java you can declare a field 'static transient' - the compiler doesn't complain. This doesn't seem to be useful in any way since static fields are not serialized, as we all know.
我刚刚发现在 Java 中你可以声明一个字段“静态瞬态”——编译器不会抱怨。众所周知，这似乎没有任何用处，因为静态字段未序列化。
But I wonder, is there actually a case where 'static transient' fields are useful?
但我想知道，实际上是否存在“静态瞬态”字段有用的情况？

Nope - you said it yourself, static fields aren't serialized.
不 - 你自己说过，静态字段没有序列化。
Kinda weird that the compiler lets you do that though.
编译器允许你这样做有点奇怪。

In most cases, it is not useful. Static fields are indeed not serialized by the default serializer.
在大多数情况下，它没有用。静态字段确实没有被默认序列化器序列化。
However, statictransientfields can be detected via reflection. If someone writes its own serializer and he wants to also serialize static fields, then he mighttake the transientkeyword in consideration and skip the serialization of that particular field.
但是，statictransient可以通过反射检测场。如果有人编写了自己的序列化程序并且他还想序列化静态字段，那么他可能会考虑transient关键字并跳过该特定字段的序列化。
