方法详细资料

• setAllowedLocations

  public void setAllowedLocations​(@Nullable
                                  Resource... locations)

  By default when a Resource is found, the path of the resolved resource is compared to ensure it's under the input location where it was found. However sometimes that may not be the case, e.g. when CssLinkResourceTransformer resolves public URLs of links it contains, the CSS file is the location and the resources being resolved are css files, images, fonts and others located in adjacent or parent directories.

  This property allows configuring a complete list of locations under which resources must be so that if a resource is not under the location relative to which it was found, this list may be checked as well.

  By default ResourceWebHandler initializes this property to match its list of locations.

  参数:

  locations - the list of allowed locations

• getAllowedLocations

  @Nullable
  public Resource[] getAllowedLocations()

• resolveResourceInternal

  protected reactor.core.publisher.Mono<Resource> resolveResourceInternal​(@Nullable

  指定者:

• resolveUrlPathInternal

  protected reactor.core.publisher.Mono<String> resolveUrlPathInternal​(String path,
                                                                       List<? extends Resource> locations,
                                                                       ResourceResolverChain chain)

• getResource

  protected reactor.core.publisher.Mono<Resource> getResource​(String resourcePath,
                                                              Resource location)

  Find the resource under the given location.

  The default implementation checks if there is a readable Resource for the given path relative to the location.

  参数:

  resourcePath - the path to the resource

  location - the location to check

  返回:

  the resource, or empty Mono if none found

• checkResource

  protected boolean checkResource​(Resource resource,
                                  Resource location)
                           throws IOException

  Perform additional checks on a resolved resource beyond checking whether the resources exists and is readable. The default implementation also verifies the resource is either under the location relative to which it was found or is under one of the allowed locations.

  参数:

  resource - the resource to check

  location - the location relative to which the resource was found

  返回:

  "true" if resource is in a valid location, "false" otherwise.

  抛出:

  IOException
