scope of objects in a Web application

[raj malhotra]

Hi,

I need a general understanding about the scope of objects in a Spring based web applications. Suppose i have a a web application with a Rest Webservice. The  web application either fetches the record from database or persist the  data into database. Is Singleton ,Prototype and prototype with ScopedProxyMode.TARGET_CLASS enough. Should i look into Request scope also?

RestController - BeanObj -> ServiceImpl -> DaoImpl->DB

Regards,
Raj

Enough for what? Different types have different purposes and so different lifetimes. Why are you concerned with whether a handful of scopes is enough? Just use the right one for the right job, no matter if it's Singleton, Prototype, Request or something else still.
