在Spring Boot REST应用程序中处理压缩的请求

我有一个Spring Boot REST应用程序(1.5.6.RELEASE).我想要gzip压缩传入和传出.根据本文档 https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html 我已经设置

I have a Spring Boot REST app (1.5.6.RELEASE). I would like gzip compression incoming and outgoing. As per this documentation https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html I have set

server.compression.enabled=true
server.compression.mime-types=...

但是，这似乎仅适用于从我的服务gzip压缩响应(这就是文档实际所说的#如果启用了响应压缩.").

But this seems to only apply to gzipping responses from my service (and this is what the doc says actually "# If response compression is enabled.").

我的问题是传入的压缩请求没有被解压缩，导致JSON解析错误.

My problem is that incoming gzipped requests are not being decompressed, resulting in JSON parsing errors.

有人知道我如何在Spring Boot应用程序中打开请求解压缩吗?

Does anyone know how I can turn on request decompression in my Spring Boot app?

编辑示例:

POM片段:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.6.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

控制器代码:

@RestController
public class Controller {
    @RequestMapping(value = "/", method = RequestMethod.POST, consumes = "application/json")
    public String post(@RequestBody Map<String, String> request) {
        return request.get("key");
   }
}

使用curl测试:

$ echo '{ "key":"hello" }' > body
$ curl -X POST -H "Content-Type: application/json" --data-binary @body http://localhost:8080 # prints 'hello'
$ echo '{ "key":"hello" }' | gzip > body.gz
$ curl -X POST -H "Content-Type: application/json" -H "Content-Encoding: gzip" --data-binary @body.gz http://localhost:8080 # fails

压缩后的呼叫失败，并显示以下消息:

The gzipped call fails with message:
