• getInputStream

  public InputStream getInputStream()
                             throws IOException

  This implementation opens an InputStream for the given URL.

  It sets the useCaches flag to false, mainly to avoid jar file locking on Windows.

  返回:

  the input stream for the underlying resource (must not be null)

  抛出:

  FileNotFoundException - if the underlying resource doesn't exist

  IOException - if the content stream could not be opened

• getURL

  public URL getURL()

  This implementation returns the underlying URL reference.

  指定者:

• getURI

  public URI getURI()
             throws IOException

  This implementation returns the underlying URI directly, if possible.

  指定者:

  getURI 在接口中 Resource

  抛出:

  IOException - if the resource cannot be resolved as URI, i.e. if the resource is not available as descriptor

• isFile

  public boolean isFile()

  从类复制的说明: AbstractResource
  This implementation always returns false.

• getFile

  public File getFile()
               throws IOException

  指定者:

  getFile 在接口中 Resource

  覆盖:

  getFile 在类中 AbstractFileResolvingResource

  抛出:

  FileNotFoundException - if the resource cannot be resolved as absolute file path, i.e. if the resource is not available in a file system

  IOException - in case of general resolution/reading failures
