Class ConfigurableMimeFileTypeMap

java.lang.Object

javax.activation.FileTypeMap

org.springframework.mail.javamail.ConfigurableMimeFileTypeMap

All Implemented Interfaces:

InitializingBean

public class ConfigurableMimeFileTypeMap
extends javax.activation.FileTypeMap
implements 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.

1.2

private java.lang.String[] mappings

Used to configure additional mappings.

Constructor Detail

ConfigurableMimeFileTypeMap

public ConfigurableMimeFileTypeMap()

Method Detail

setMappingLocation

public void setMappingLocation(Resource 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

setMappings

public void setMappings(java.lang.String[] 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

afterPropertiesSet

public void afterPropertiesSet()

Creates the final merged mapping set.

Specified by:

afterPropertiesSet in interface InitializingBean

getFileTypeMap

protected final javax.activation.FileTypeMap getFileTypeMap()

Return the delegate FileTypeMap, compiled from the mappings in the mapping file and the entries in the mappings property.

setMappingLocation(org.springframework.core.io.Resource), setMappings(java.lang.String[]), createFileTypeMap(org.springframework.core.io.Resource, java.lang.String[])

createFileTypeMap

protected javax.activation.FileTypeMap createFileTypeMap(Resource mappingLocation,
                                             java.lang.String[] mappings)
                                                  throws java.io.IOException

Compile a FileTypeMap from the mappings in the given mapping file and the given mapping entries.

The default implementation creates an Activation Framework MimetypesFileTypeMap, passing in an InputStream from the mapping resource (if any) and registering the mapping lines programmatically.

Parameters:

mappingLocation - a mime.types mapping resource (can be null)

mappings - MIME type mapping lines (can be null)

Returns:

the compiled FileTypeMap

Throws:

java.io.IOException - if resource access failed

public java.lang.String getContentType(java.io.File file)

Delegates to the underlying FileTypeMap.

getContentType

public java.lang.String getContentType(java.lang.String fileName)

Delegates to the underlying FileTypeMap.
