tomcat 8.5.27, this problem is still not fixed.
Removed <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol"/>
and gzip works again.
<Connector .....
compression="on"
port="443"
protocol="org.apache.coyote.http11.Http11AprProtocol"
......... >
<UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol"/>

In server.xml,like this:
<Connector ..... compressableMimeType="text/html,text/javascript"
compression="on"
compressionMinSize="2048"
noCompressionUserAgents="gozilla, traviata"
port="8443"
protocol="org.apache.coyote.http11.Http11AprProtocol"
......... >
<UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol"/>
<SSLHostConfig
........../>
</SSLHostConfig>
</Connector>
The compression="on" doesn't work when use this config.
But if I remove "UpgradeProtocol" element ,it works;
Simply put, when using http / 2, the compression function is not available.

I think that using compression with dynamic data (as in your configuration) is
insecure. There are well-known CRIME and BREACH attacks. See
https://en.wikipedia.org/wiki/CRIME
Tomcat 8.5 and 9 can be configured to serve pre-compressed static files. This
is configured with init-param "precompressed" of DefaultServlet.

Nginx can use gzip compression with http/2 module.
So I think, tomcat may also support.（sad...）
Maybe tomcat will support in the future...

Ok. I would say it is unlikely integrated compression is implemented in HTTP/2
as it was in the HTTP/1.1. We'll see, but it's probably a good idea to plan to
migrate to a different solution for compression.
Right now, there's also no provision to pull configuration from the Connector
as well, the UpgradeProtocol element is independent.

--- Comment #14 from Mark Thomas <ma...@apache.org> ---
This feature is not broken. It was implemented at the end of last year and has
been confirmed to be working as intended on multiple occasions since then.
To expand on Remy's previous comment.
Do not re-open this report means exactly that. Do not re-open this report.
This report is the enhancement request to add compression support to HTTP/2.
That support has been added so this issue has been resolved. That you can't get
it to work does not mean that the feature is broken. Given that:
- there are no relevant code changes since the feature was added
- it has been confirmed working multiple times
the more likely explanation is a configuration issue, not a bug.
Looking at the configuration provided in comment #10, that report at least is
clearly a configuration issue.
Configuration issues are support questions and Bugzilla is not a support forum.
Hence re-opening a bug in order to obtain configuration help is not acceptable
behaviour in this community.
The correct place to seek configuration assistance is the users mailing list.
Hence the second part of Remy's comment.
