MIME 媒体类型介绍
这篇文章主要回答这些内容：
-
如何思考解决这个问题？
-
如何获取文件的 MIME？
-
如何实现 MIME 类型获取的工具？
起因：我准备实现一个 HTTP 服务器，在 Response 的
Content-Type要设置文件类型，这种类型也是有规范的，那就是 MIME，我现在需要一个工具获取文件的类型。
首先想到的是看能不能用 jdk 的工具，查了下 jdk8 有个 MimetypesFileTypeMap 类可以用，但我用的是 jdk11，在这个版本已经剔除了这个类，如果用就需要增加一个依赖。这种方式的
使用方法：
MimetypesFileTypeMap mimeTypesMap = new MimetypesFileTypeMap();
mimeTypesMap.getContentType(filePath);
// 如果是高版本的jdk需要增加以下依赖
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
在读这个 jdk 工具的源码后，发现这个工具并不是根据文件的魔数来判断的，是根据文件的扩展名判断的（e.g. .html），jdk 工具存储了一个配置文件，以获取文件扩展名与 MIME 的映射关系。
魔数：是在文件内容中固定的一个数字，标识一类文件
jdk 配置文件的部分内容：
#sun.net.www MIME content-types table
#
# Property fields:
#
# <description> ::= 'description' '=' <descriptive string>
# <extensions> ::= 'file_extensions' '=' <comma-delimited list, include '.'>
# <image> ::= 'icon' '=' <filename of icon image>
# <action> ::= 'browser' | 'application' | 'save' | 'unknown'
# <application> ::= 'application' '=' <command line template>
#
#
# The "we don't know anything about this data" type(s).
# Used internally to mark unrecognized types.
#
content/unknown: description=Unknown Content
unknown/unknown: description=Unknown Data Type
#
# The template we should use for temporary files when launching an application
# to view a document of given type.
#
temp.file.template: /tmp/%s
#
# The "real" types.
#
application/octet-stream: \
description=Generic Binary Stream;\
file_extensions=.saveme,.dump,.hqx,.arc,.o,.a,.bin,.exe,.z,.gz
application/oda: \
description=ODA Document;\
file_extensions=.oda
application/pdf: \
description=Adobe PDF Format;\
file_extensions=.pdf
... ...
了解到这一点，我想到所有的 HTTP 应该都有判断文件类型这步操作，我准备看下 nginx 的 MIME 配置，到了配置文件中，果然见到了配置文件。如下：
types {
text/html html htm shtml;
text/css css;

}
到这里我就明白了这个功能如何实现完成，把 nginx 或者 jdk 的配置文件内容转换成一个判断程序就行了。以下是这个工具的实现。
