cn.taketoday.web.accept.MappingMediaTypeFileExtensionResolver

cn.taketoday.web.accept.AbstractMappingContentNegotiationStrategy

cn.taketoday.web.accept.PathExtensionContentNegotiationStrategy

所有已实现的接口:

ContentNegotiationStrategy, MediaTypeFileExtensionResolver

public class PathExtensionContentNegotiationStrategy
extends AbstractMappingContentNegotiationStrategy

A ContentNegotiationStrategy that resolves the file extension in the request path to a key to be used to look up a media type.

If the file extension is not found in the explicit registrations provided to the constructor, the MediaType.fromFileName(String) is used as a fallback mechanism.

PathExtensionContentNegotiationStrategy

public PathExtensionContentNegotiationStrategy()

Create an instance without any mappings to start with. Mappings may be added later on if any extensions are resolved through the Java Activation framework.

PathExtensionContentNegotiationStrategy

public PathExtensionContentNegotiationStrategy(@Nullable
 Map<String,MediaType> mediaTypes)

Create an instance with the given map of file extensions and media types.

PathExtensionContentNegotiationStrategy

public PathExtensionContentNegotiationStrategy(@Nullable
 Object servletContext,
 @Nullable
 Map<String,MediaType> mediaTypes)

Create an instance with the given map of file extensions and media types.

方法详细资料

assertServletContext

static void assertServletContext(@Nullable
 Object servletContext)

getMediaTypeKey

@Nullable
protected String getMediaTypeKey(RequestContext request)

从类复制的说明: AbstractMappingContentNegotiationStrategy

Extract a key from the request to use to look up media types.

指定者:

getMediaTypeKey 在类中 AbstractMappingContentNegotiationStrategy

返回:

the lookup key, or null if none

handleNoMatch

@Nullable
protected MediaType handleNoMatch(RequestContext request,
 String extension)
                           throws HttpMediaTypeNotAcceptableException

Resolve file extension via ServletContext.getMimeType(String) and also delegate to base class for a potential MediaTypeFactory lookup.

覆盖:

handleNoMatch 在类中 AbstractMappingContentNegotiationStrategy

抛出:

HttpMediaTypeNotAcceptableException

getMediaTypeForResource

@Nullable
public MediaType getMediaTypeForResource(cn.taketoday.core.io.Resource resource)

A public method exposing the knowledge of the path extension strategy to resolve file extensions to a MediaType in this case for a given Resource. The method first looks up any explicitly registered file extensions first and then falls back on MediaType.fromFileName(String) if available.

参数:

resource - the resource to look up

返回:

the MediaType for the extension, or null if none found
