        An invocation of this convenience constructor of the form.

         new PathResource(file);
         

        behaves in exactly the same way as the expression

         new PathResource(file.toPath());
         
        Parameters:
        file - the file to use
      • PathResource

                     throws java.io.IOException
        Deprecated.
        Construct a new PathResource from a URI object.

        Must be an absolute URI using the file scheme.

        Parameters:
        uri - the URI to build this PathResource from.
        Throws:
        java.io.IOException - if unable to construct the PathResource from the URI.

        An invocation of this convenience constructor of the form.

         new PathResource(url);
         

        behaves in exactly the same way as the expression

         new PathResource(url.toURI());

    • Method Detail

      • isSameName

        public static boolean isSameName​(java.nio.file.Path pathA,
                                         java.nio.file.Path pathB)
        Deprecated.
        Test if the paths are the same name.

        If the real path is not the same as the absolute path then we know that the real path is the alias for the provided path.

        For OS's that are case insensitive, this should return the real (on-disk / case correct) version of the path.

        We have to be careful on Windows and OSX.

        Assume we have the following scenario:

           Path a = new File("foo").toPath();
           Files.createFile(a);
           Path b = new File("FOO").toPath();
         

        There now exists a file called foo on disk. Using Windows or OSX, with a Path reference of FOO, Foo, fOO, etc.. means the following

                                |  OSX    |  Windows   |  Linux
         -----------------------+---------+------------+---------
         Files.exists(a)        |  True   |  True      |  True
         Files.exists(b)        |  True   |  True      |  False
         Files.isSameFile(a,b)  |  True   |  True      |  False
         a.equals(b)            |  False  |  True      |  False
         

        See the javadoc for Path.equals() for details about this FileSystem behavior difference

        We also cannot rely on a.compareTo(b) as this is roughly equivalent in implementation to a.equals(b)

      • isSame

        public boolean isSame​(Resource resource)
        Deprecated.
        Description copied from class: Resource
        Return true if the passed Resource represents the same resource as the Resource. For many resource types, this is equivalent to Object.equals(Object), however for resources types that support aliasing, this maybe some other check (e.g. Files.isSameFile(Path, Path)).
        Overrides:
        isSame in class Resource
        Parameters:
        resource - The resource to check
        Returns:
        true if the passed resource represents the same resource.
      • addPath

        addPath in class Resource
        Parameters:
        subPath - The path segment to add, which is not encoded. The path may be non canonical, but if so then the resulting Resource will return true from Resource.isAlias().
        Returns:
        the Resource for the resolved path within this Resource.
        Throws:
        java.io.IOException - if unable to resolve the path
        java.net.MalformedURLException - if the resolution of the path fails because the input path parameter is malformed, or a relative path attempts to access above the root resource.
