Serializable is a serialization method specific to the java language and cannot be cross-language.
RestController is a serialization scheme for cross-language schemes such as json,xml or protobuf, which is naturally not related to Serializable

first clarify the role of serialization:

• when you want to save the object state in memory to a file or database
• when you want to spread objects over the network

, please refer to the article http://blademastercoder.githu.

secondly, according to the above function, your vo needs neither persistence nor network transmission, so there will be no problem, just front-end data parsing and conversion to back-end vo

I guess your concern is whether these annotations have anything to do with Serializable ,

my understanding is:

@ RestController ( @ ResponseBody + @ Controller ), @ RequestBody are not directly related to Serializable , and the potential problems of not implementing the interface have nothing to do with these annotations.
