java - values - Interface/enum que enumera las constantes de tipo mime estándar

mediatype

Question

Estoy buscando entre las bibliotecas estándar (como apache commons, jax, jboss, javax) para una interfaz o enumeración que enumera los valores de todo el tipo de mime estándar (también conocido como tipo de contenido).

Esta interfaz no debe ser gravada con demasiada profundidad con otras clases que dificultarían incluir todo el grupo como código fuente gwt.

por ejemplo

interface ContentType{
String JSON = "Application/JSON";
blah ... blah ...
}

o,

enum ContentType{
JSON("Application/JSON"),
blah ... blah ...
}

Answer 1

¡También hay una clase MediaType en androidannotations en caso de que quieras usar con Android! Mira here .

Answer 2

Ahora también existe la clase org.apache.http.entity.ContentType del paquete org.apache.httpcomponents.httpcore , comenzando desde 4.2 hasta.

Answer 3

Como se señala en una respuesta anterior, puede usar javax.ws.rs.core.MediaType que tiene las constantes requeridas.

También quería compartir un enlace realmente genial y útil que encontré que da una referencia a todas las constantes Javax en un solo lugar: https://docs.oracle.com/javaee/7/api/constant-values.html .

Answer 4

Como ya se publicó en una respuesta anterior, los tipos MIME más comunes se configuran en un servidor web. Por ejemplo, en tomcat conf / tenemos web.xml con el siguiente MIME configurado:

 <mime-mapping>
<extension>abs</extension>
<mime-type>audio/x-mpeg</mime-type>
</mime-mapping>
<mime-mapping>
<extension>ai</extension>
<mime-type>application/postscript</mime-type>
</mime-mapping>
<mime-mapping>
<extension>aif</extension>
<mime-type>audio/x-aiff</mime-type>
</mime-mapping>
...

Cree un escucha de inicio que se active cuando la aplicación web se inicie y analice este archivo XML y cree los ENUMS para usted y los vincule al contexto de servlet para compartirlos en sentido descendente.

Answer 5

Java 7 al rescate!

Puede pasar el archivo o el nombre del archivo y devolverá el tipo MIME.

String mimeType = MimetypesFileTypeMap
.getDefaultFileTypeMap()
.getContentType(attachment.getFileName());

Answer 6

Lo resolví con una clase estática:

mimeTypes = new HashMap<String, String>() {

Answer 7

Si está utilizando Spring Framework, entonces hay una clase MediaType para tipos de contenido comunes:

 MediaType.TEXT_HTML
MediaType.TEXT_PLAIN
MediaType.TEXT_XML
MediaType.APPLICATION_JSON
MediaType.IMAGE_JPEG
...

Answer 8

Si estás en Android tienes múltiples opciones, donde solo la primera es una especie de "enumeración":

• HTTP (que ha quedado obsoleto en la API 22), por ejemplo
  HTTP.PLAIN_TEXT_TYPE o
• MimeTypeMap , por ejemplo
  final String mime = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
  Ver también FileProvider.getType() .
• URLConnection que proporciona los siguientes métodos:
  • guessContentTypeFromStream(InputStream is)
  • guessContentTypeFromName(String url)
  • getFileNameMap()

Por ejemplo

@Override
public String getType(Uri uri) {
return URLConnection.getFileNameMap().getContentTypeFor(
uri.getLastPathSegment());
}

Answer 9

Tenemos una clase de Guava para esto: com.google.common.net.MediaType .

Fue lanzado con Guava 12 como se indica en el código fuente y en el Issue 823 . Sources están disponibles, también.
