Why Gzip compression not work in aws-elasticbeanstalk + nginx + tomcat environment?

Question

The system is up and running in elasticbeanstalk here is added configs in the .ebextensions folder (located in folder root)

nginx-proxy.config

option_settings:
  aws:elasticbeanstalk:environment:proxy:
    GzipCompression: 'true'
    ProxyServer: nginx

gzip.config

files:
        /etc/nginx/conf.d/gzip.conf:
        content: |
                gzip on;
                gzip_types application/json application/xml text/html text/xml text/plain application/javascript text/css;
                gzip_vary on;

Tried with tomcat-settings.config too, but the result is the same

option_settings:
  aws:elasticbeanstalk:environment:proxy:
    GzipCompression: 'true'
    ProxyServer: nginx

Tried by adding this header for postman too

'accept-encoding: gzip'

Answer 1

its works after apply this

@Bean
public Filter compressingFilter() {
    CompressingFilter compressingFilter = new CompressingFilter();
    return compressingFilter;
}

dependency used this one

    <dependency>
        <groupId>net.sourceforge.pjl-comp-filter</groupId>
        <artifactId>pjl-comp-filter</artifactId>
        <version>1.6.4</version>
    </dependency>
            

work as a charm :-)
