public class OpenTransactionInViewFilter
extends OncePerRequestFilter

Servlet filter that wraps execution in a transaction. A TransactionTemplate must exist in the associated WebApplicationContext and is identified by name via setTransactionManagerBeanName() (by default, DEFAULT_TRANSACTION_MANAGER_BEAN_NAME).

Transaction properties are configurable via filter <init-param>'s isolation, propagation, and readOnly.
