【问题描述】：
我正在尝试在 Undertow 中启用请求解压缩 (gzip)。在文档中，它指定这是由RequestEncodingHandler 处理的。
我在 Spring config 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，但是当我尝试上传带有 Content-Encoding: gzip 标头的 gzip 压缩文件时，出现以下错误：
14:51:03.378 [XNIO-2 task-1] ERROR io.undertow.request.io - UT005090: Unexpected failure

设置此自定义的正确方法是什么？
