public class WebContentInterceptor extends WebContentGenerator implements HandlerInterceptor
All the settings supported by this interceptor can also be set on AbstractController. This interceptor is mainly intended for applying checks and preparations to a set of controllers mapped by a HandlerMapping.

void |
setAlwaysUseFullPath(boolean alwaysUseFullPath)
Set if URL lookup should always use full path within current servlet
context.
|
void |
setCacheMappings(Properties cacheMappings)
Map specific URL paths to specific cache seconds.
|
void |
setPathMatcher(PathMatcher pathMatcher)
Set the PathMatcher implementation to use for matching URL paths
against registered URL patterns, for determining cache mappings.
|
void |
setUrlDecode(boolean urlDecode)
Set if context path and request URI should be URL-decoded.
|
void |
setUrlPathHelper(UrlPathHelper urlPathHelper)
Set the UrlPathHelper to use for resolution of lookup paths.

Only relevant for the "cacheMappings" setting.
public void setUrlDecode(boolean urlDecode)
Uses either the request encoding or the default encoding according to the Servlet spec (ISO-8859-1).
Only relevant for the "cacheMappings" setting.
public void setUrlPathHelper(UrlPathHelper urlPathHelper)
Use this to override the default UrlPathHelper with a custom subclass, or to share common UrlPathHelper settings across multiple HandlerMappings and MethodNameResolvers.
Only relevant for the "cacheMappings" setting.
public void setCacheMappings(Properties cacheMappings)
Overrides the default cache seconds setting of this interceptor. Can specify "-1" to exclude a URL path from default caching.
Supports direct matches, e.g. a registered "/test" matches "/test", and a various Ant-style pattern matches, e.g. a registered "/t*" matches both "/test" and "/team". For details, see the AntPathMatcher javadoc.

HandlerInterceptorDispatcherServlet 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.

next interceptor or the handler itself. Else, DispatcherServlet assumes
that this interceptor has already dealt with the response itself.ServletExceptionprotected Integer lookupCacheSeconds(String urlPath)
