Class ResourceHandlerRegistry
- java.lang.Object
- org.springframework.web.reactive.config.ResourceHandlerRegistry
public class ResourceHandlerRegistry extends Object
Stores registrations of resource handlers for serving static resources such as images, css files and others through Spring WebFlux including setting cache headers optimized for efficient loading in a web browser. Resources can be served out of locations under web application root, from the classpath, and others.To create a resource handler, use
addResourceHandler(String...)providing the URL path patterns for which the handler should be invoked to serve static resources (e.g."/resources/**").Then use additional methods on the returned
ResourceHandlerRegistrationto add one or more locations from which to serve static content from (e.g. {"/","classpath:/META-INF/public-web-resources/"}) or to specify a cache period for served resources.- Since:

resourceLoader- the resource loader to use
Method Detail
setResourceUrlProvider
public void setResourceUrlProvider(@Nullable ResourceUrlProvider resourceUrlProvider)
Configure theResourceUrlProviderthat can be used byResourceTransformerinstances.- Parameters:
resourceUrlProvider- the resource URL provider to use- Since:

addResourceHandler
public ResourceHandlerRegistration addResourceHandler(String... patterns)
Add a resource handler for serving static resources based on the specified URL path patterns. The handler will be invoked for every incoming request that matches to one of the specified path patterns.Patterns like

- a
ResourceHandlerRegistrationto use to further configure the registered resource handler
hasMappingForPattern
public boolean hasMappingForPattern(String pathPattern)
Whether a resource handler has already been registered for the given path pattern.
setOrder
public ResourceHandlerRegistry setOrder(int order)
Specify the order to use for resource handling relative to otherHandlerMappings configured in the Spring configuration.The default value used is
Integer.MAX_VALUE-1.
getHandlerMapping
@Nullable protected AbstractUrlHandlerMapping getHandlerMapping()
Return a handler mapping with the mapped resource handlers; ornullin case of no registrations.
