接口/枚举列出标准的MIMEtypes常量
我正在寻找一个接口或枚举列出所有标准MIMEtypes（又名内容types）的值的标准库（如Apache公用程序，jax，jboss，javax）。
这个接口不应该与其他类太深，以至于难以将整个接口包含为gwt源代码。
例如
interface ContentType{ String JSON = "Application/JSON"; blah ... blah ... } 要么，
enum ContentType{ JSON("Application/JSON"), blah ... blah ... }
我们有一个番石榴类： com.google.common.net.MediaType 。
它与源代码和问题823中所述的Guava 12一起发布 。 资源也可用。
也许从这里开始： http : //docs.oracle.com/javaee/6/api/javax/ws/rs/core/MediaType.html
staticjava.lang.String APPLICATION_ATOM_XML "application/atom+xml" staticMediaType APPLICATION_ATOM_XML_TYPE "application/atom+xml" staticjava.lang.String APPLICATION_FORM_URLENCODED "application/x-www-form-urlencoded" staticMediaType APPLICATION_FORM_URLENCODED_TYPE "application/x-www-form-urlencoded" staticjava.lang.String APPLICATION_JSON "application/json" staticMediaType APPLICATION_JSON_TYPE "application/json" staticjava.lang.String APPLICATION_OCTET_STREAM "application/octet-stream" staticMediaType APPLICATION_OCTET_STREAM_TYPE "application/octet-stream" staticjava.lang.String APPLICATION_SVG_XML "application/svg+xml" staticMediaType APPLICATION_SVG_XML_TYPE "application/svg+xml" staticjava.lang.String APPLICATION_XHTML_XML "application/xhtml+xml" staticMediaType APPLICATION_XHTML_XML_TYPE "application/xhtml+xml" staticjava.lang.String APPLICATION_XML "application/xml" staticMediaType APPLICATION_XML_TYPE "application/xml" staticjava.lang.String MEDIA_TYPE_WILDCARD The value of a type or subtype wildcard: "*" staticjava.lang.String MULTIPART_FORM_DATA "multipart/form-data" staticMediaType MULTIPART_FORM_DATA_TYPE "multipart/form-data" staticjava.lang.String TEXT_HTML "text/html" staticMediaType TEXT_HTML_TYPE "text/html" staticjava.lang.String TEXT_PLAIN "text/plain" staticMediaType TEXT_PLAIN_TYPE "text/plain" staticjava.lang.String TEXT_XML "text/xml" staticMediaType TEXT_XML_TYPE "text/xml" staticjava.lang.String WILDCARD "*/*" staticMediaType WILDCARD_TYPE "*/*"
如果您使用的是Spring Framework，那么通用内容types有一个MediaType类：
MediaType.TEXT_HTML MediaType.TEXT_PLAIN MediaType.TEXT_XML MediaType.APPLICATION_JSON MediaType.IMAGE_JPEG ...
现在还有包org.apache.httpcomponents.httpcore类，从4.2开始。
来自JAX-RS的 javax.ws.rs.core.MediaType
Java 7来拯救！
您可以传递文件或文件名，它将返回MIMEtypes。
String mimeType = MimetypesFileTypeMap .getDefaultFileTypeMap() .getContentType(attachment.getFileName());
http://docs.oracle.com/javase/7/docs/api/javax/activation/MimetypesFileTypeMap.html
在androidannotations中还有一个MediaType类，以防你想用于android！ 看到这里 。
如果你在Android上，你有多种select，只有第一种是“枚举”：
-
HTTP（在API 22中已被弃用）
HTTP.PLAIN_TEXT_TYPE或 - 例如，
MimeTypeMap
final String mime = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
另请参阅FileProvider.getType()。 - 提供以下方法的
URLConnection：-
guessContentTypeFromStream(InputStream is) -
guessContentTypeFromName(String url) -
getFileNameMap()
-
例如
@Override public String getType(Uri uri) { return URLConnection.getFileNameMap().getContentTypeFor( uri.getLastPathSegment()); }
我用一个静态类来解决这个问题：
@SuppressWarnings("serial") public class MimeTypes { private static final HashMap<String, String> mimeTypes; static { mimeTypes = new HashMap<String, String>() { { put(".323", "text/h323"); put(".3g2", "video/3gpp2");

put(".xss", "application/xml"); put(".xtp", "application/octet-stream"); put(".xwd", "image/x-xwindowdump"); put(".z", "application/x-compress"); put(".zip", "application/x-zip-compressed"); } }; } public static String getMimeType(String extension) { if (extension == null) { return null; } if (!extension.startsWith(".")) { extension = "." + extension.toLowerCase(Locale.getDefault()); } String mime = mimeTypes.get(extension); return mime != null ? mime : "application/octet-stream"; } }
正如前面的答案中已经发布的，大多数常见的MIMEtypes都是在Web服务器中configuration的。 例如在tomcat conf /中，我们有web.xml，configuration了以下MIME：
<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> ...
创build一个启动监听器，在启动Web应用程序时启动，parsing这个XML文件并为您创buildENUMS，并将它绑定到servlet上下文以便下游共享。
