类 ResourceUrlProvider

java.lang.Object

cn.taketoday.context.support.ApplicationObjectSupport

cn.taketoday.web.resource.ResourceUrlProvider

所有已实现的接口:

cn.taketoday.beans.factory.Aware, cn.taketoday.context.ApplicationContextAware, cn.taketoday.context.ApplicationListener<cn.taketoday.context.event.ContextRefreshedEvent>, EventListener

public class ResourceUrlProvider
extends cn.taketoday.context.support.ApplicationObjectSupport
implements cn.taketoday.context.ApplicationListener<cn.taketoday.context.event.ContextRefreshedEvent>, cn.taketoday.context.ApplicationContextAware

A central component to use to obtain the public URL path that clients should use to access a static resource.

This class is aware of Framework MVC handler mappings used to serve static resources and uses the ResourceResolver chains of the configured ResourceHttpRequestHandlers to make its decisions.

从以下版本开始:

ResourceUrlProvider

public ResourceUrlProvider()

方法详细资料

setPathMatcher

public void setPathMatcher(cn.taketoday.core.PathMatcher pathMatcher)

Configure a PathMatcher to use when comparing target lookup path against resource mappings.

getPathMatcher

public cn.taketoday.core.PathMatcher getPathMatcher()

Return the configured PathMatcher.

setHandlerMap

public void setHandlerMap(@Nullable
 Map<String,ResourceHttpRequestHandler> handlerMap)

Manually configure the resource mappings.

Note: by default resource mappings are auto-detected from the ApplicationContext. However if this property is used, the auto-detection is turned off.

getHandlerMap

public Map<String,ResourceHttpRequestHandler> getHandlerMap()

Return the resource mappings, either manually configured or auto-detected when the ApplicationContext is refreshed.

isAutodetect

public boolean isAutodetect()

Return false if resource mappings were manually configured, true otherwise.

onApplicationEvent

public void onApplicationEvent(cn.taketoday.context.event.ContextRefreshedEvent event)

指定者:

onApplicationEvent 在接口中 cn.taketoday.context.ApplicationListener<cn.taketoday.context.event.ContextRefreshedEvent>

detectResourceHandlers

protected void detectResourceHandlers(cn.taketoday.context.ApplicationContext appContext)

getForRequestUrl

@Nullable
public final String getForRequestUrl(RequestContext request,
 String requestUrl)

A variation on getForLookupPath(String) that accepts a full request URL path (i.e. including context and servlet path) and returns the full request URL path to expose for public use.

参数:

request - the current request

requestUrl - the request URL path to resolve

返回:

the resolved public URL path, or null if unresolved

getLookupPathIndex

private int getLookupPathIndex(RequestContext request)

getEndPathIndex

private int getEndPathIndex(String lookupPath)

getForLookupPath

@Nullable
public final String getForLookupPath(String lookupPath)

Compare the given path against configured resource handler mappings and if a match is found use the ResourceResolver chain of the matched ResourceHttpRequestHandler to resolve the URL path to expose for public use.

It is expected that the given path is what MVC would use for request mapping purposes, i.e. excluding context and servlet path portions.

If several handler mappings match, the handler used will be the one configured with the most specific pattern.

参数:

lookupPath - the lookup path to check

返回:

the resolved public URL path, or null if unresolved
