java.lang.Objectorg.springframework.core.io.AbstractResource
org.springframework.core.io.FileSystemResource
public class FileSystemResource
Resource implementation for java.io.File handles. Obviously supports resolution as File, and
also as URL.
File| Constructor Summary | |
|---|---|
FileSystemResource(java.io.File file)
Create a new FileSystemResource from a File handle. |
|
FileSystemResource(java.lang.String path)
Create a new FileSystemResource from a file path. |
|
| Method Summary | |
|---|---|
Resource |
createRelative(java.lang.String relativePath)
This implementation creates a FileSystemResource, applying the given path relative to the path of the underlying file of this resource descriptor. |
boolean |
equals(java.lang.Object obj)
This implementation compares the underlying File references. |
boolean |
exists()
This implementation returns whether the underlying file exists. |
java.lang.String |
getDescription()
This implementation returns a description that includes the absolute path of the file. |
java.io.File |
getFile()
This implementation returns the underlying File reference. |
java.lang.String |
getFilename()
This implementation returns the name of the file. |
java.io.InputStream |
getInputStream()
This implementation opens a FileInputStream for the underlying file. |
java.io.OutputStream |
getOutputStream()
This implementation opens a FileOutputStream for the underlying file. |
java.lang.String |
getPath()
Return the file path for this resource. |
java.net.URI |
getURI()
This implementation returns a URI for the underlying file. |
java.net.URL |
getURL()
This implementation returns a URL for the underlying file. |
int |
hashCode()
This implementation returns the hash code of the underlying File reference. |
boolean |
isReadable()
This implementation checks whether the underlying file is marked as readable (and corresponds to an actual file with content, not to a directory). |
boolean |
isWritable()
This implementation checks whether the underlying file is marked as writable (and corresponds to an actual file with content, not to a directory). |

public FileSystemResource(java.io.File file)
Note: When building relative resources via createRelative(java.lang.String), the relative path will apply at the same
directory level: e.g. new File("C:/dir1"), relative path "dir2" -> "C:/dir2"! If you prefer to have relative
paths built underneath the given root directory, use the constructor with a
file path to append a trailing slash to the root path: "C:/dir1/", which indicates this directory as root for
all relative paths.
file - a File handlepublic FileSystemResource(java.lang.String path)
Note: When building relative resources via createRelative(java.lang.String), it makes a difference whether the specified
resource base path here ends with a slash or not. In the case of "C:/dir1/", relative paths will be built
underneath that root: e.g. relative path "dir2" -> "C:/dir1/dir2". In the case of "C:/dir1", relative paths will
apply at the same directory level: relative path "dir2" -> "C:/dir2".
