ResourceHandlerRegistration
public ResourceHandlerRegistration(ResourceLoader resourceLoader, String... pathPatterns)
Create aResourceHandlerRegistration
instance.- 参数:
resourceLoader
- a resource loader for turning a String location into aResource
pathPatterns
- one or more resource URL path patterns

addResourceLocations
public ResourceHandlerRegistration addResourceLocations(String... resourceLocations)
Add one or more resource locations from which to serve static content. Each location must point to a valid directory. Multiple locations may be specified as a comma-separated list, and the locations will be checked for a given resource in the order specified.For example, {
"/"
,"classpath:/META-INF/public-web-resources/"
} allows resources to be served both from the web application root and from any JAR on the classpath that contains a/META-INF/public-web-resources/
directory, with resources in the web application root taking precedence.- 返回:

ResourceHandlerRegistration
instance, for chained method invocation
setCacheControl
public ResourceHandlerRegistration setCacheControl(CacheControl cacheControl)
Specify theCacheControl
which should be used by the resource handler.- 参数:
cacheControl
- the CacheControl configuration to use- 返回:
- the same
ResourceHandlerRegistration
instance, for chained method invocation
resourceChain
public ResourceChainRegistration resourceChain(boolean cacheResources)
Configure a chain of resource resolvers and transformers to use. This can be useful, for example, to apply a version strategy to resource URLs.If this method is not invoked, by default only a simple
PathResourceResolver
is used in order to match URL paths to resources under the configured locations.- 参数:
cacheResources
- whether to cache the result of resource resolution; setting this to "true" is recommended for production (and "false" for development, especially when applying a version strategy)- 返回:

resourceChain
public ResourceChainRegistration resourceChain(boolean cacheResources, Cache cache)
Configure a chain of resource resolvers and transformers to use. This can be useful, for example, to apply a version strategy to resource URLs.If this method is not invoked, by default only a simple

is used in order to match URL paths to resources under the configured locations.- 参数:

- whether to cache the result of resource resolution; setting this to "true" is recommended for production (and "false" for development, especially when applying a version strategycache
- the cache to use for storing resolved and transformed resources; by default aConcurrentMapCache
is used. Since Resources aren't serializable and can be dependent on the application host, one should not use a distributed cache but rather an in-memory cache.- 返回:

protected String[] getPathPatterns()
Returns the URL path patterns for the resource handler.
getRequestHandler
protected ResourceWebHandler getRequestHandler()
Returns aResourceWebHandler
