public final class MappedInterceptor extends java.lang.Object implements HandlerInterceptor
HandlerInterceptor
along with
include (and optionally exclude) path patterns to which the interceptor should apply.
Also provides matching logic to test if the interceptor applies to a given request path.
A MappedInterceptor can be registered directly with any
AbstractHandlerMethodMapping
. Furthermore, beans of type MappedInterceptor
are automatically detected by AbstractHandlerMethodMapping
(including
ancestor ApplicationContext's) which effectively means the interceptor is
registered "globally" with all handler mappings.

HandlerInterceptor
DispatcherServlet processes a handler in an execution chain, consisting of any number of interceptors, with the handler itself at the end. With this method, each interceptor can decide to abort the execution chain, typically sending a HTTP error or writing a custom response.
Note: special considerations apply for asynchronous
request processing. For more details see
AsyncHandlerInterceptor
.
The default implementation returns true

HandlerInterceptor
DispatcherServlet processes a handler in an execution chain, consisting of any number of interceptors, with the handler itself at the end. With this method, each interceptor can post-process an execution, getting applied in inverse order of the execution chain.
Note: special considerations apply for asynchronous
request processing. For more details see
AsyncHandlerInterceptor
.
The default implementation is empty.

HandlerInterceptor
Note: Will only be called if this interceptor's preHandle
method has successfully completed and returned true
!
As with the postHandle
method, the method will be invoked on each
interceptor in the chain in reverse order, so the first interceptor will be
the last to be invoked.

request processing. For more details see
