Spring REST 控制器不处理 gzip 压缩输入

Spring REST controller does not handle gzip compressed input

我已根据文档在 application.properties 中设置以下属性,从而设置我的 spring 启动应用程序来处理 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

然而,在收到 gzip 压缩输入后,Spring REST 控制器似乎无法解码输入。我收到 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 引导处理压缩的 JSON 有效负载?

Spring 引导版本是 v2.3.2.RELEASE

我认为 server.compression.enabled=true 是关于 response,而不是 request。 对于 request,您可能需要编写自己的 Filter 或使用任何现有的。 在互联网上,我可以找到 和一些可能有帮助的示例。

Spring 不提供此功能,因为它是网络服务器的一部分。 处理此问题的一种方法是提供一个 filter/component 来处理传入请求。
