在Spring Boot中配置Undertow RequestEncodingHandler

Question

我试图在Undertow中启用请求解压缩（gzip）。在文档中，它指定由RequestEncodingHandler处理。我在Spring配置中创建了以下组件

@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)
                }
            }
        )
    }
}

看起来Spring正在执行此代码但是当我尝试使用Content-Encoding: gzip头文件上传gzipped文件时，我收到以下错误：

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

    at java.base/java.lang.Thread.run(Thread.java:834)

设置此自定义的正确方法是什么？

显然发布的代码是正确的，问题是gzipped文件，我正在测试它
