像Logger这样的静态类没有被序列化。为什么？
答案 0 :(得分：0)
将类标记为"RMI TCP Connection(733561)-10.219.11.2" #130543 daemon prio=5 os_prio=0 tid=0x00007f513007a800 nid=0x64d0 waiting on condition [0x00007f4f7e8e5000]

时，您要求Java运行时序列化类的对象或实例。这有助于将对象中的数据转换为可存储的格式，以便存储或通过strean发送。
另一方面，Serializable成员不属于任何类，并且不属于序列化范围。因此，标记您的班级static不会影响任何班级的Serializable成员。
反序列化对象时，加载类时，其所有类的static成员都已在其他JVM中初始化。因此，将静态字段数据作为序列化对象的一部分发送是没有意义的。

希望这有帮助！
