MimeTypes

Java (JVM) lookup table for standard mime types and their extensions.

API Usage

Get the extension for a mime type:

MimeTypes.getInstance().getByType("image/png").getExtension(); // returns "png"

Get all possible extensions for a mime type:

MimeTypes.getInstance().getByType("image/png").getExtensions(); // returns String[]{"png"}
MimeTypes.getInstance().getByType("text/html").getExtensions(); // returns String[]{"html", "htm"}

Get mime type for an extension:

MimeTypes.getInstance().getByExtension("png").getMimeType(); // returns "image/png"

Register a custom mimetype and query it up later:

MimeTypes.getInstance().register(new MimeType("application/vnd.awesome", new String[]{"wsm"}));
MimeTypes.getInstance().getByType("application/vnd.awesome").getExtension(); // returns "wsm"

Initialize with a custom "mime.types" definitions file:

new MimeTypes(Paths.get("/path/to/custom/mime.types"));

Alternatively:

MimeTypes.blank().load(Paths.get("/path/to/custom/mime.types"));

Build

Using maven:

mvn package

If you want the sources and javadocs too:

mvn package -P release

Maven central coordinates

New releases are submitted to central, to use:

<dependencies>
  <dependency>
    <groupId>com.github.amr</groupId>
    <artifactId>mimetypes</artifactId>
    <version>0.0.3</version>
  </dependency>
</dependencies>
