Serializable class with unserializable injected member in JAVA

I have a serializable class which has some members injected from guice module. However, these members are unserializable and I can't force the declaration of them with Serializable interface. How shall I write readObject and writeObject functions for this class to support the serializing the instance of this class?

You can either declare these fields as transient to prevent automatic serialization or implement your own readObject and writeObject. The implementation will depend on your application. If after deserialization you can stand without the not serializable members, just ignore them. If you need them you have to find a way to get them.

In your case these are Guice-injected objects. If you are planning to deserialize your object in context of Guice you have to inject these dependencies. I do not know Guice enough but in Spring I know 2 ways:

fetch these object programmatically from current Spring (Guice in your case) application context.
Spring has factory that can inject all needed dependencies itself. I believe that Guice should have similar functionality.
