官方文档原文：[https://docs.spring.io/spring-boot/docs/2.1.5.RELEASE/reference/htmlsingle/\#how-to-enable-http-response-compression][https_docs.spring.io_spring-boot_docs_2.1.5.RELEASE_reference_htmlsingle_how-to-enable-http-response-compression]

HTTP response compression is supported by Jetty, Tomcat, and Undertow. It can be enabled in `application.properties`, as follows:

server.compression.enabled=true

By default, responses must be at least 2048 bytes in length for compression to be performed. You can configure this behavior by setting the `server.compression.min-response-size` property.

By default, responses are compressed only if their content type is one of the following:

*  `text/html`
 *  `text/xml`
 *  `text/plain`
 *  `text/css`
 *  `text/javascript`
 *  `application/javascript`
 *  `application/json`
 *  `application/xml`

You can configure this behavior by setting the `server.compression.mime-types` property.

其中，

*  server.compression.enabled   表示是否开启 
 *  server.compression.mime-types    表示需要压缩的内容的类型    “text/html”, “text/xml”, “text/plain”, “text/css”, “text/javascript”, “application/javascript”, “application/json”, “application/xml”
 *  server.compression.min-response-size    需要压缩的内容的最小长度，默认单位：B    2048，等同于配置2KB，或者直接写2KB也可以。官方文档中就是这么写的。如下。

# EMBEDDED SERVER CONFIGURATION (ServerProperties)
    server.address= # Network address to which the server should bind.
    server.compression.enabled=false # Whether response compression is enabled.
    server.compression.excluded-user-agents= # Comma-separated list of user agents for which responses should not be compressed.
    server.compression.mime-types=text/html,text/xml,text/plain,text/css,text/javascript,application/javascript,application/json,application/xml # Comma-separated list of MIME types that should be compressed.
    server.compression.min-response-size=2KB # Minimum "Content-Length" value that is required for compression to be performed.
