最近在弄文件上传、下载、在线预览时经常需要设置请求标头或者响应标头的Content-Type 属性。所以研究了一下spring支持哪些Content-Type,通过研究MediaTypeFactory.getMediaType的源码,可以得知spring是将支持的Content-Type 维护在/org/springframework/http/mime.types文件中。
private static MultiValueMap<String, MediaType> parseMimeTypes() { InputStream is = MediaTypeFactory.class.getResourceAsStream("/org/springframework/http/mime.types"); try { BufferedReader reader = new BufferedReader(new InputStreamReader(is, StandardCharsets.US_ASCII)); Throwable var2 = null; try { MultiValueMap<String, MediaType> result = new LinkedMultiValueMap(); label111: while(true) { String line; if ((line = reader.readLine()) != null) { if (line.isEmpty() || line.charAt(0) == '#') { continue; } String[] tokens = StringUtils.tokenizeToStringArray(line, " \t\n\r\f"); MediaType mediaType = MediaType.parseMediaType(tokens[0]); int i = 1; while(true) { if (i >= tokens.length) { continue label111; } String fileExtension = tokens[i].toLowerCase(Locale.ENGLISH); result.add(fileExtension, mediaType); ++i; } } LinkedMultiValueMap var5 = result; return var5; } } catch (Throwable var17) { var2 = var17; throw var17; } finally { if (reader != null) { if (var2 != null) { try { reader.close(); } catch (Throwable var16) { var2.addSuppressed(var16); } } else { reader.close(); } } } } catch (IOException var19) { throw new IllegalStateException("Could not load '/org/springframework/http/mime.types'", var19); } }
通过上面查找文件的路径找到了org.springframework:spring-web包下http目录中的mime.types文件
结果打开后居然发现 有多达1838个Content-Type,不过许多都是被注释掉的。过滤掉被注释的最终能被获取出来的一共是982个,本着好记性不如烂笔头的精神,我把这982个Content-Type已经它对应的文件后缀,整理了一下,形成了下面的表格,也方便以后查阅。

MediaTypeFactory是spring-web包下的工具类,需要在pom引用spring-web包,本例使用的是:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version> 2.2.4.RELEASE</version> </dependency>
从源码中可以看到MediaTypeFactory一共提供了三个对外方法,支持通过传入文件名或者Resource对象来获取Content-Type:
public static Optional<MediaType> getMediaType(@Nullable Resource resource) { return Optional.ofNullable(resource).map(Resource::getFilename).flatMap(MediaTypeFactory::getMediaType); } public static Optional<MediaType> getMediaType(@Nullable String filename) { return getMediaTypes(filename).stream().findFirst(); } public static List<MediaType> getMediaTypes(@Nullable String filename) { Optional var10000 = Optional.ofNullable(StringUtils.getFilenameExtension(filename)).map((s) -> { return s.toLowerCase(Locale.ENGLISH); }); MultiValueMap var10001 = fileExtensionToMediaTypes; var10001.getClass(); return (List)var10000.map(var10001::get).orElse(Collections.emptyList()); }
我们用传入文件名的方式测试一下:
public static void main(String[] args) { MediaType mediaType = MediaTypeFactory.getMediaType("测试.pdf").get(); String mediaTypeString = mediaType.toString(); System.out.println(mediaTypeString); }
输出结果:
application/pdf
Apache Tika 是一个内容分析工具包,可以检测上千种文件类型,并提取它们的元数据和文本。tika在设计上十分精巧,单一的接口使它易于使用,在搜索引擎索引,内容分析,翻译等诸多方面得到了广泛使用。
使用Apache Tika首先需要在pom引用:
<dependency> <groupId>org.apache.tika</groupId> <artifactId>tika-core</artifactId> <version>1.28.4</version> </dependency>
获取Content-Type 主要是用到其中detect的通过源码我们可以得知(源码太长了就不放了)detect支持通过传入String(文件名)、URL、File、Path、byte[]、InputStream等类型来解析以获取Content-Type
我们用传入byte[]的方式测试一下:
public static void main(String[] args) { File file = new File("D:\\书籍\\电子书\\其它\\自然哲学的数学原理.pdf"); byte[] fileContent = new byte[(int) file.length()]; try (FileInputStream inputStream = new FileInputStream(file)) { inputStream.read(fileContent); } catch (IOException e) { e.printStackTrace(); } Tika tika = new Tika(); String mediaTypeString = tika.detect(fileContent); System.out.println(mediaTypeString); }
输出结果:
application/pdf
注意tika.detect返回的是String类型,如果想像第一种方式一样得到MediaType对象,还需要转换一下。
MediaType.parseMediaType(mediaTypeString);
