Spring REST Controller 不处理 gzip 压缩输入

Question

我已经根据文档在 application.properties 中设置以下属性，将 Spring Boot 应用程序设置为处理 HTTP 服务器压缩:

server.compression.enabled=true
server.compression.mime-types=application/json,application/xml,text/html,text/xml,text/plain,application/javascript,text/css

尽管如此，在接收到 gzip 压缩输入后，Spring REST Controller 似乎无法解码输入。我收到一个 HttpMessageNotReadableException。以下是日志中的相关行:

是否需要一些额外的配置才能使 Spring Boot 处理压缩的 JSON 负载？

Spring Boot 版本为 v2.3.2.RELEASE。

我相信server.compression.enabled=true是关于响应，而不是请求。 对于请求，您可能需要编写自己的Filter或使用任何现有的。 在互联网上查找，我可以找到this一些可能有帮助的例子。
