Interface HandlerMethodInterceptor

All Known Implementing Classes:

WebEventPublisher

public interface HandlerMethodInterceptor

HandlerMethod Interceptor that allows for customized HandlerMethod execution chains. Applications can register any number of existing or custom interceptors for certain groups of handlers, to add common preprocessing behavior without needing to modify each handler implementation.

A HandlerInterceptor gets called before the appropriate HandlerAdapter triggers the execution of the handler itself.
