InitializingBean
public class ConfigurableMimeFileTypeMap extends FileTypeMap implements InitializingBean
Spring-configurableFileTypeMap
implementation that will read MIME type to file extension mappings from a standard JavaMail MIME type mapping file, using a standardMimetypesFileTypeMap
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 inactivation.jar
). This can be overridden using themappingLocation
property.Additional mappings can be added via the
mappings
bean property, as lines that follow themime.types
file format.- 从以下版本开始:

setMappingLocation
public void setMappingLocation(Resource mappingLocation)
Specify theResource
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(String... mappings)
Specify additional MIME type mappings as lines that follow themime.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.- 指定者:

getFileTypeMap
protected final FileTypeMap 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
MimetypesFileTypeMap
, passing in an InputStream from the mapping resource (if any) and registering the mapping lines programmatically.- 参数:
mappingLocation
- amime.types
mapping resource (can benull
)mappings
- an array of MIME type mapping lines (can benull
)- 返回:
- the compiled FileTypeMap
- 抛出:
IOException
- if resource access failed- 另请参阅:
