Class ConfigurableMimeFileTypeMap
- All Implemented Interfaces:
InitializingBean
FileTypeMap
implementation that will read
MIME type to file extension mappings from a standard JavaMail MIME type
mapping file, using a standard MimetypesFileTypeMap
underneath.
The mapping file should be in the following format, as specified by the Java Activation Framework:
# map text/html to .htm and .html files text/html html htm HTML HTMLines starting with
#
are treated as comments and are ignored. All
other lines are treated as mappings. Each mapping line should contain the MIME
type as the first entry and then each file extension to map to that MIME type
as subsequent entries. Each entry is separated by spaces or tabs.
By default, the mappings in the mime.types
file located in the
same package as this class are used, which cover many common file extensions
(in contrast to the out-of-the-box mappings in activation.jar
).
This can be overridden using the mappingLocation
property.
Additional mappings can be added via the mappings
bean property,
as lines that follow the mime.types
file format.

afterPropertiesSet
public void afterPropertiesSet()Creates the final merged mapping set.- Specified by:

in interfaceInitializingBean
-
getFileTypeMap
Return the delegate FileTypeMap, compiled from the mappings in the mapping file and the entries in themappings
property. -
createFileTypeMap
protected FileTypeMap createFileTypeMap(@Nullable Resource mappingLocation, @Nullable String[] mappings) throws IOException Compile aFileTypeMap
from the mappings in the given mapping file and the given mapping entries.The default implementation creates an Activation Framework

, passing in an InputStream from the mapping resource (if any) and registering the mapping lines programmatically.- Parameters:
mappingLocation
- amime.types
mapping resource (can benull
)mappings
- an array of MIME type mapping lines (can benull
)- Returns:
- the compiled FileTypeMap
- Throws:
IOException
