java - 在 Apache Tomcat 8 中对图像和字体进行 Gzip 压缩

Question

这是 Apache Tomcat 8 中 gzip 压缩的配置

<Connector port="7070" maxHttpHeaderSize="8192"
       maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
       enableLookups="false" redirectPort="8443" acceptCount="100"
       connectionTimeout="20000" disableUploadTimeout="true" 
       compression="on" 
       compressionMinSize="256" 
       noCompressionUserAgents="gozilla, traviata" 
       compressableMimeType="text/html,text/xml,text/plain,text/css,application/javascript,font/otf,font/woff,
       font/woff2,image/gif,image/jpg,image/png"/>

png 图片可以。它不适用于 jpg 图像和 woff2 字体，如下所示。

我已经试过了，还是不行

image/jpg <or> image/jpeg <or> application/octet-stream

font/woff <or> font/woff2 <or> application/font-woff <or> application/font-woff2

从 Chrome 测试

您正在尝试压缩已压缩的文件 (gzip)，如 woff/woff2、jpg 等。在我看来，这只是资源浪费。并非每种类型的文件都可以压缩(请参阅:Fastly blog about gzip settings)。

以下是 FaSTLy 建议默认压缩的类型:

Extensions: js css html json ico eot otf ttf

Content Types: text/html application/x-javascript text/css application/javascript text/javascript text/plain text/xml application/json application/vnd.ms-fontobject application/x-font-opentype application/x-font-truetype application/x-font-ttf application/xml font/eot font/opentype font/otf image/svg+xml image/vnd.microsoft.icon
