基于TIKA（重量级，准确率很高）
介绍
apache-tika是一个文档解析库，用于解析各种文件中的内容和元数据，当然也可以用来判断文件类型
支持的文件类型（1500种左右）
可以在这个网站上查阅，tika支持的所有文件类型https://www.digipres.org/formats/sources/tika/formats
- ID 表示文件类型
- Filename pattern 表示该文件类型的文件后缀
- Has Magic? 表示该类型是否具有文件头标识（如果没有则使用文件后缀匹配）
- MIME Types 表示等价的文件类型有哪些（有些文件类型是等价的，同义不同名）
- Super-Type 表示基于哪个文件类型拓展而来
优缺点
优点
大部分文件都可以准确的判断出文件类型，准确率非常高，同时也可以解析文件元数据和文件内容
缺点
需要集成各种文件的tika拓展解析包，依赖包很多，打包出来会比较大
依赖
<!-- tika核心功能包 -->
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-core</artifactId>
<version>2.9.2</version>
</dependency>
<!-- tika文件解析器整合包 -->
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-parsers-standard-package</artifactId>

</dependency>
代码示例
// 建议定义为静态常量，可复用
Tika tika = new Tika();
// 传入file对象，得到文件类型，判断失败则返回application/octet-stream
String contentType = tika.detect(new File(""));
// 传入输入流，得到文件类型，判断失败则返回application/octet-stream
String contentType = tika.detect(new ByteArrayInputStream(""));
// 传入字节数组，得到文件类型，判断失败则返回application/octet-stream
String contentType = tika.detect(new byte[1024]);
// 传入文件名，得到文件类型，判断失败则返回application/octet-stream
String contentType = tika.detect("");
// 传入Path对象，得到文件类型，判断失败则返回application/octet-stream
String contentType = tika.detect(Path.of(""));
// 传入URL，得到文件类型，判断失败则返回application/octet-stream
String contentType = tika.detect(new URL(""));
基于 jakarta.activation（javax.activation）
介绍
jakarta.activation是Jakarta中的一个文件类型解析库
支持的文件类型（可以自定义文件类型匹配列表）

优缺点
优点
轻量级集成，解析速度很快，底层基于Map进行匹配
缺点
只能根据文件后缀进行匹配，准确率不高
依赖（二选一，取决于使用项目使用哪套体系）
<!-- jakarta -->
<dependency>
<groupId>jakarta.activation</groupId>
<artifactId>jakarta.activation-api</artifactId>
<version>2.1.3</version>
</dependency>
<!-- javax -->
<dependency>
<groupId>javax.activation</groupId>
<artifactId>javax.activation-api</artifactId>
<version>1.2.0</version>
</dependency>
代码示例
// 建议定义为静态常量，可复用
MimetypesFileTypeMap mimeTypeMap = new MimetypesFileTypeMap();
// 传入文件名，得到文件类型，判断失败则返回application/octet-stream
String contentType = tika.getContentType("");
总结
实际项目中，建议两种方案一起使用，先使用tika进行判断，如何结果为application/octet-stream，再使用activation进行判断
