Giao diện/enum liệt kê các hằng số loại mime tiêu chuẩn

Question

Tôi đang tìm kiếm trong số các thư viện chuẩn (như commache commons, jax, jboss, javax) cho một giao diện hoặc enum liệt kê các giá trị của tất cả các loại mime tiêu chuẩn (aka content- kiểu).

Giao diện này không nên bị vướng bận quá sâu với các lớp khác sẽ khiến việc đưa toàn bộ nhóm trở thành mã nguồn gwt trở nên khó khăn.

ví dụ

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

hay,

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

Answer 1

Chúng tôi có Ổi Lớp học cho điều này: com.google.common.net.MediaType.

Nó được phát hành với số 12 Như đã nêu trong mã nguồn và trong Issue 823. Sources cũng khả dụng.

Answer 2

Như đã được đăng trong câu trả lời trước đó, loại MIME phổ biến nhất được cấu hình trong một máy chủ web. Ví dụ trong conf tomcat/chúng tôi có web.xml với sau đây cấu hình 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> 
... 

Tạo listener khởi động mà đá trong khi ứng dụng web được bắt đầu và phân tích tập tin XML này và tạo ra sự đếm cho bạn và kết nối nó đến ngữ cảnh servlet để chia sẻ hạ lưu.

Answer 3

có lẽ một sự khởi đầu ở đây: 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     "*/*" 

Answer 4

Nếu bạn đang sử dụng Spring Framework sau đó là một lớp MediaType với nhiều loại nội dung phổ biến:

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

Answer 5

javax.ws.rs.core.MediaType từ JAX-RS

Answer 6

Hiện nay, cũng là lớp org.apache.http.entity.ContentType từ gói org.apache.httpcomponents.httpcore, bắt đầu từ 4.2 trở lên.

Answer 7

Java 7 để giải cứu!

Bạn có thể chuyển tệp hoặc tên tệp và nó sẽ trả về loại MIME.

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

http://docs.oracle.com/javase/7/docs/api/javax/activation/MimetypesFileTypeMap.html

Answer 8

Ngoài ra còn có một lớp MediaType trong androidannotations trong trường hợp bạn muốn sử dụng với Android! Xem here.

Answer 9

Nếu bạn đang ở trên android bạn có nhiều sự lựa chọn, mà chỉ là người đầu tiên là một loại "enum":

• HTTP (mà đã bị phản đối API 22), ví dụ
  HTTP.PLAIN_TEXT_TYPE hoặc
• MimeTypeMap, ví dụ
  final String mime = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
  Xem thêm FileProvider.getType().
• URLConnection cung cấp các phương pháp sau:
  • guessContentTypeFromStream(InputStream is)
  • guessContentTypeFromName(String url)
  • getFileNameMap()

Ví dụ

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