是否可以为serializable类创建锁暂态？ [英] Is it okay to to make the lock transient for a Serializable class?

问题描述

我有一个实现 Serializable 的类，并且通过类型<$ c $的 lock 对象保护这个类的不变量c> Object 。是否可以暂时使用，还是可以产生任何不必要的副作用？

代码：

  class MyClass implements Serializable {
 
 private final transient lock = new Object（）; 
 .... 
} 
  

解决方案

这很好，只要你在反序列化后重新创建对象，以便您可以在其上进行同步。

此外，您可能需要< a href =http://stackoverflow.com/questions/2968876/final-transient-fields-and-serialization>删除 final 修饰符。 / p>

这是决定这是否值得的麻烦。

I have a class that implements Serializable and I protect the invariant of this class via a lock object which is of type Object. Is it okay to make it transient or can it have any unwanted side effects?

Code :

class MyClass implements Serializable{

 private final transient lock = new Object();
  ....
}

解决方案

This is fine, as long as you recreate the object upon de-serialization so that you have something to synchronize on.

Also, you'll probably have to remove the final modifier.

It's up to you to decide whether this is worth the hassle.
