resteasy ContainerRequestFilter didn't work in springboot - spring-boot

Question

resteasy 3.1.3.Final and springboot 1.5.7
I want do somthing before the request go ino the restful method,but it never worked.
here is the restful method interface.
#Path("/demo")
#Consumes({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
#Produces({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
public interface DemoService {
#POST
#Path("/query")
List<EntityDemoInfo> queryByType(QueryRequest requst);
}
Here is the filter.
#Provider
#PreMatching
public class RequestFilter implements HttpRequestPreprocessor,ContainerRequestFilter{
#Override
public void filter(ContainerRequestContext requestContext) throws IOException {
System.out.println("-----------------");
}
#Override
public void preProcess(HttpRequest request) {
System.out.println("================");
}
}
It never go in the filter and print the log,even if i tried the annotations #Provider/#PreMatching/#Configuration in any combination.
Later i think maybe something registry problem,and tried to add #Bean in #SpringBootApplication class.This can print what I register,however when debugging request the registry/factory din't have my RequestFilter, thus it didn't work. What's wrong with it? thanks !
#Bean
public SynchronousDispatcher synchronousDispatcher() {
ResteasyProviderFactory providerFactory = ResteasyProviderFactory.getInstance();
RequestFilter requestFilter = new RequestFilter();
providerFactory.getContainerRequestFilterRegistry().registerSingleton(requestFilter);
SynchronousDispatcher dispatcher = new SynchronousDispatcher(providerFactory);
dispatcher.addHttpPreprocessor(requestFilter);
System.out.println("*****************");
System.out.println(providerFactory.getContainerRequestFilterRegistry().preMatch());
return dispatcher;
}
As 'paypal' codes do in https://github.com/paypal/resteasy-spring-boot , I added RequestFilter like Hantsy mentioned below, it didn't work!
Here is the log.

The resteasy documentation provides simple guide for intgrating resteasy with Spring and Spring Boot. Hope these links are helpful.
Resteasy and Spring Integration
Spring Boot starter, described in the 43.4. Spring Boot starter section of the Resteasy doc.
If you are using Spring Boot as described in the doc, just register you custom Filter in your Application class.
#Component
#ApplicationPath("/sample-app/")
public class JaxrsApplication extends Application {
#Override
public Set<Object> getSingletons() {
Set<Object> singletons = new HashSet<>();
singletons.add(yourFilter);
return singletons;
}
}
Updated: I forked the paypal/resteasy-spring-boot, and modified the sample-app, added a EchoFitler for demo purpose.
Check the source codes from my Github account.
Run the sample-app via mvn spring-boot:run.
Use curl to test the apis.
# curl -v -X POST -H "Content-Type:text/plain" -H "Accept:application/json" http://localhost:8080/sample-app/echo -d "test"
Note: Unnecessary use of -X or --request, POST is already inferred.
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)
> POST /sample-app/echo HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.56.0
> Content-Type:text/plain
> Accept:application/json
> Content-Length: 4

< HTTP/1.1 200

< Date: Fri, 20 Oct 2017 07:19:43 GMT

{"timestamp":1508483983603,"echoText":"test"}* Connection #0 to host localhost left intact
And you will see the filtering info in the spring-boot console.
filtering request context:org.jboss.resteasy.core.interception.jaxrs.PreMatchContainerRequestContext#1ca8d1e4
filtering request/response context:org.jboss.resteasy.core.interception.jaxrs.ResponseContainerRequestContext#1787a18c
org.jboss.resteasy.core.interception.jaxrs.ContainerResponseContextImpl#4aad828e
Hope this is helpful.
