Jersey ContainerRequestFilter not triggered

Question

I\'m trying to use a ContainerRequestFilter to enforce some authentication on a Tomcat based Jersey application. I followed this document. Problem : the filter

Answer 1

Some hints:

1. Make sure you're using JAX-RS version 2.17.

2. Make sure you're using the right imports in your filter:

   • import javax.ws.rs.container.ContainerRequestContext;
   • import javax.ws.rs.container.ContainerRequestFilter;

3. Add the @Provider annotation

Answer 2

Instead of using the @Provider annotation (which did not work in my case), you can register your ContainerRequestFilter manually with your JerseyServletFactory:

JerseyServletFactory jerseyServletFactory = new JerseyServletFactory(config);
HttpServlet myServiceServlet = jerseyServletFactory.create(myResource);

// Register your ContainerRequestFilter like this
jerseyServletFactory.addRequestFilter(new MyFilter());

httpServer.register(myServiceServlet, "/api");
httpServer.start();

Answer 3

If you were stuck like me, note that TomEE 1.7.X uses JAX-RS 1.1, which does not include ContainerRequestFilter.

Answer 4

Instead of javax.ws.rs, i used com.sun.jersey and it worked

import com.sun.jersey.spi.container.ContainerRequestFilter import com.sun.jersey.spi.container.ContainerRequest

Dropwizard users need to do this

environment.jersey().getResourceConfig()
           .getContainerRequestFilters()
           .add(filter);

Answer 5

Okay, I didn't get that the jersey.config.server.provider.packages init param needs to reference not only service classes (API endpoints) but ALL the classes including filters.

Now it works :

<init-param>  
  <param-name>jersey.config.server.provider.packages</param-name>  
  <param-value>com.hck.debate.rest.controller;com.hck.debate.rest.security</param-value>
</init-param>
<init-param>
    <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>
    <param-value>com.hck.debate.rest.security.AuthFilter</param-value>
</init-param>

Answer 6

The minimum requirements to work filters with jersey:

• add @Provider annotation to filter class
• the namespace of filter class has to be included in 'jersey.config.server.provider.packages' init-param

Any other settings aren't required (e.g. 'com.sun.jersey.spi.container.ContainerRequestFilters' init-param or ResourceConfig)
