serialversionuid be displayed in a serializable class, giving it a definite value .There are two ways to explicitly define SERIALVERSIONUID:1, in some cases, you want different versions of the class to be serializable compatible, so you need to ensure that the different versions of the class have the same serialversionuid;2. In some cases, you do not want different versions of the class to be serializable compatible, so you need to ensure that different versions of the class have different seri

I personally think that dynamic languages like Ruby are much simpler. I personally think that dynamic languages like Ruby are much simpler. Reply content: I don't think it should be static or dynamic, but strong or weak. A strong type is less prone to errors than a weak type, while a weak type only saves some code.

Request, returns Response, and many times Response is not a static file, so an application is required to generate the corresponding Response based on the request. The application is mainly used to process the related business logic, read or update the database, and return the corresponding Response according to different Request. Note that this is not the WEB server itself to do this, it is only responsible for the Http protocol level and some such
