- 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.- 从以下版本开始:

public boolean hasMappingForPattern(String pathPattern)
Whether a resource handler has already been registered for the given path pattern.
setOrder
public ResourceHandlerRegistry setOrder(int order)
