Gzip 压缩在我的 Spring boot 1.5.10.RELEASE 项目中不起作用

Sta*_*low 14 java gzip angularjs spring-boot

我正在使用 Spring Boot 1.5.10.RELEASE 版本。Gzip 压缩不起作用。

http://localhost:9000 --> http://localhost:8080/api/..

不同端口上的 Angularjs 和 rest api。启用 CrossOrigin 以接受来自 angularjs ui 的请求。

使用嵌入式 tomcat 服务器部署 spring boot 应用程序。不使用 http2 属性即server.http2.enabled=true

Angualrjs 调用 rest api。以下是 $http 服务

$http({
  method: method,
  url: url,
  params: params,
  data: body,
  headers: {
    Authorization: token,
    "Content-type": 'application/json'
  }
});

休息 api 响应大小大约 25 MB，所以我想压缩响应。

我在application.properties 中添加了众所周知的属性来应用 gzip 压缩。 Spring Boot 1.5.10 支持的属性

# Enable response compression
server.compression.enabled=true

# The comma-separated list of mime types that should be compressed
server.compression.mime-types=text/html,text/xml,text/plain,text/css,text/javascript,application/javascript,application/json

# Compress the response only if the response size is at least 1KB
server.compression.min-response-size=1024

我已经观察到网络选项卡并且没有观察到Content-Encoding: gzip在响应头中。

我没有在响应标头中遵循预期的标头

Content-Encoding: gzip
Vary: Accept-Encoding

客户端/服务器端需要任何更改吗？

---[Edit-1] ------------- 在单个项目中尝试 gzip ，但在我的项目中不起作用。

以下是从浏览器调用rest api时的响应头

Content-Encoding: gzip

-----[Edit-2]-----Ziplet----

使用ziplet依赖项我可以压缩响应，但我想使用 spring boot gzip 压缩。
