java - How is the DTO objects transferred from client to server in spring-struts web application without implementing serializable -

-

i have web application developed using spring - struts framework deployed in tomcat 8 server. application hosted in 1 server.

the application code layered

action | bpo | dao | dto | entityobject

only few dto classes implements serializable interface dto objects being written file using ehcache caching state.

do need implement serializable interface dto classes?

with reference below link says not necessary implement serializable dto classes.

dto implementation of serializable interface

if how dto object gets transferred client side server side without serialization?

the serializable used java.io , it's needed if want keep objects in session. other frameworks using serializable behind scene perform serialization. if don't know object serialized using java.io.serializable better add interface dtos.

the client-side might use other serialization json, xml, etc., doesn't affect processes running serialization on server-side , should handled separately code or other framework struts or spring, doesn't matter.
