Class ModuleResource

All Implemented Interfaces:
InputStreamSource, Resource

public class ModuleResource extends AbstractResource
Resource implementation for Module resolution, performing getInputStream() access via Module.getResourceAsStream(java.lang.String).

Alternatively, consider accessing resources in a module path layout via ClassPathResource for exported resources, or specifically relative to a Class via ClassPathResource(String, Class) for local resolution within the containing module of that specific class. In common scenarios, module resources will simply be transparently visible as classpath resources and therefore do not need any special treatment at all.

    • ModuleResource

      public ModuleResource(Module module, String path)
      Create a new ModuleResource for the given Module and the given resource path.
      module - the runtime module to search within
      path - the resource path within the module
  • Method Details

    • getModule

      public final Module getModule()
      Return the Module for this resource.
    • getPath

      public final String getPath()
      Return the path for this resource.
    • getInputStream

      public InputStream getInputStream() throws IOException
      Description copied from interface: InputStreamSource
      Return an InputStream for the content of an underlying resource.

      It is expected that each call creates a fresh stream.

      This requirement is particularly important when you consider an API such as JavaMail, which needs to be able to read the stream multiple times when creating mail attachments. For such a use case, it is required that each getInputStream() call returns a fresh stream.

      the input stream for the underlying resource (must not be null)
      FileNotFoundException - if the underlying resource does not exist
      IOException - if the content stream could not be opened

    • createRelative

      public Resource createRelative(String relativePath)
      Description copied from class: AbstractResource
      This implementation throws a FileNotFoundException, assuming that relative resources cannot be created for this resource.
      Specified by:
      createRelative in interface Resource
      createRelative in class AbstractResource
      relativePath - the relative path (relative to this resource)
      the resource handle for the relative resource
    • getFilename

      @Nullable public String getFilename()
      Description copied from class: AbstractResource
      This implementation always returns null, assuming that this resource type does not have a filename.
      Specified by:
      getFilename in interface Resource
      getFilename in class AbstractResource
    • getDescription

      public String getDescription()
      Description copied from interface: Resource
      Return a description for this resource, to be used for error output when working with the resource.

      Implementations are also encouraged to return this value from their toString method.

    • equals

      public boolean equals(@Nullable Object obj)
      Description copied from class: AbstractResource
      This implementation compares description strings.

      public int hashCode()
      Description copied from class: AbstractResource
