Exception loading groovy class when start nginx

[Georgios Papageorgiou]

Hello, 

I have this groovy class 

package gr.test.headers;

import java.io.IOException;

import java.util.Map;

import java.util.concurrent.ConcurrentHashMap;

import static nginx.clojure.java.Constants.PHASE_DONE;

import nginx.clojure.ChannelCloseAdapter;

import nginx.clojure.java.NginxJavaFilterRequest;

import nginx.clojure.java.NginxJavaHeaderFilter;

public class ResponseFilterHeaders implements NginxJavaHeaderFilter {

static Map<Long, NginxJavaFilterRequest> headerFilterRequests = new ConcurrentHashMap<Long, NginxJavaFilterRequest>();

public ResponseFilterHeaders() {

}

@Override

public Object[] doFilter(int status, Map<String, Object> request, Map<String, Object> responseHeaders)

throws IOException {

System.err.println("============= Inside invoke ResponseFilterHeaders =============");

System.err.println(status);

System.err.println(request);

return PHASE_DONE;

}

}

and when i am trying to start nginx i get the excpetion

java.lang.ClassCastException: gr.test.headers.ResponseFilterHeaders cannot be cast to nginx.clojure.java.NginxJavaRingHandler

at nginx.clojure.groovy.NginxGroovyHandlerFactory.newInstance(NginxGroovyHandlerFactory.java:36)

at nginx.clojure.NginxHandlerFactory.fetchHandler(NginxHandlerFactory.java:46)

at nginx.clojure.NginxClojureRT.registerCode(NginxClojureRT.java:866)

2017/12/13 15:38:15 [error] 3796#6728: invalid groovy header_filter code : gr.test.headers.ResponseFilterHeaders

my nginx.conf file is like this...

  location / {

  resolver 8.8.8.8;

          rewrite_handler_type 'groovy';

          rewrite_handler_name 'gr.test.HelloGroovy';

  header_filter_type 'groovy';

  header_filter_name 'gr.test.headers.ResponseFilterHeaders';

  body_filter_type 'groovy';

  body_filter_name 'gr.test.body.ResponseFilterBody';

  proxy_pass $mytarget;

}

The first groovy class HelloGroovy is loaded by the NginxGroovyHandlerFactory with no error.

If i change the ResponseFilterHeaders and ResponseFilterBody classes as .java than .groovy and the types in nginx.conf from groovy to java 

the nginx is being started and all are working as expected.

I use nginx-clojure 0.4.5

Thanks
