All Implemented Interfaces:
InitializingBean

Spring-configurable 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 HTM

Lines 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.

Method from org.springframework.mail.javamail.ConfigurableMimeFileTypeMap Detail:
 public  void afterPropertiesSet() {
		getFileTypeMap();
}
Creates the final merged mapping set.
 protected FileTypeMap createFileTypeMap(Resource mappingLocation,
    String[] mappings) throws IOException {
		MimetypesFileTypeMap fileTypeMap = (mappingLocation != null) ?
				new MimetypesFileTypeMap(mappingLocation.getInputStream()) : new MimetypesFileTypeMap();
		if (mappings != null) {
			for (int i = 0; i <  mappings.length; i++) {
				fileTypeMap.addMimeTypes(mappings[i]);
			}
		}
		return fileTypeMap;
}
Compile a FileTypeMap from the mappings in the given mapping file and the
given mapping entries.
Default implementation creates an Activation Framework MimetypesFileTypeMap,
passing in an InputStream from the mapping resource (if any) and registering
the mapping lines programmatically.
 public String getContentType(File file) {
		return getFileTypeMap().getContentType(file);
}
Delegates to the underlying FileTypeMap.
 public String getContentType(String fileName) {
		return getFileTypeMap().getContentType(fileName);
}
Delegates to the underlying FileTypeMap.
 protected final FileTypeMap getFileTypeMap() {
		if (this.fileTypeMap == null) {
			try {
				this.fileTypeMap = createFileTypeMap(this.mappingLocation, this.mappings);
			}
			catch (IOException ex) {
				throw new IllegalStateException(
						"Could not load specified MIME type mapping file: " + this.mappingLocation);
			}
		}
		return fileTypeMap;
}
Return the delegate FileTypeMap, compiled from the mappings in the mapping file
and the entries in the mappings property.
 public  void setMappingLocation(Resource mappingLocation) {
	                                	 
		this.mappingLocation = mappingLocation;
}
Specify the Resource from which mappings are loaded.
Needs to follow the mime.types file format, as specified
by the Java Activation Framework, containing lines such as:

text/html html htm HTML HTM
 public  void setMappings(String[] mappings) {
		this.mappings = mappings;
}
Specify additional MIME type mappings as lines that follow the
mime.types file format, as specified by the
Java Activation Framework, for example:

text/html html htm HTML HTM
