在Spring Boot中配置Undertow RequestEncodingHandler

Question

I am trying to enable request decompressing (gzip) in Undertow. In the documentation its specified that this is handled by RequestEncodingHandler . I have created following component in Spring config

@Component
class UndertowWebServerCustomizer : WebServerFactoryCustomizer<UndertowServletWebServerFactory> {
    override fun customize(factory: UndertowServletWebServerFactory) {
        factory.addDeploymentInfoCustomizers(
            UndertowDeploymentInfoCustomizer { deploymentInfo ->
                deploymentInfo.addInitialHandlerChainWrapper { handler ->
                    RequestEncodingHandler(handler)
                        .addEncoding("gzip", GzipStreamSourceConduit.WRAPPER)
                        .addEncoding("deflate", InflatingStreamSourceConduit.WRAPPER)
                }
            }
        )
    }
}

Looks like Spring is executing this code but when I try to upload gzipped file with Content-Encoding: gzip header I get following error:

14:51:03.378 [XNIO-2 task-1] ERROR io.undertow.request.io - UT005090: Unexpected failure

What is the correct way to setup this customization?

显然发布的代码是正确的，问题是gzipped文件，我正在测试它
