What Java web design structure to choose for client and server side validation?

Question

We are currently looking for a java framework that has simplified server-side and client-side validation, Spring, Hibernate, Play is the choice of the framework we are looking for, we use annotation-based development, and this structure will also determine our choice of javascript. What is the best structure (in architecture) when checking both client-side and server-side?

Answer 1

Client side validation (assuming "client side" means javascript) is a myth. This makes the user interface more enjoyable - no questions asked - but it cannot be called "validation" because nothing that comes from the client can be considered valid; until it is checked on the server.

Server-side validation is also not monolithic - there are at least 3 components:

• Restrictions on data storage (for example, non-zero, maximum length, uniqueness, referential integrity, etc.) are set at the database level.
• Validating a domain model (ensuring that your objects are valid)
• Client input validation (user interface and, to a lesser extent, API-based validation)
