Jersey Api 未通过过滤器发送请求

Question

The ContainerRequestFilter is not being applied when receving request.

This is my fist Stackoverflow question so i do not really know what details to add in my question.

Here is my filter

package tjo.tjaa;

@Provider
 class Securityfilter implements ContainerRequestFilter {


    private static final String AUTHORIZATION_HEADER="authorization";
    private static final String AUTHORIZATION_HEADER_PREFIX="Basic";
    private static final String SECURITY_URL="security";

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        //this is where i want to execute code
        return;
 }

}

And here is my web.xml

<?xml version="1.0" encoding="UTF-8"?>

I am assuming there are multiple ways to add filter implementations to the JAX-RS. One way to add custom filters is to add them to the Application class implementation. In your case, you would have an implementation of Application class and provide the custom filter under getClasses API:

public class RestApplication extends Application {

  @Override
  public Set<Class<?>> getClasses() {
    return Sets.newHashSet(
        SecurityFilter.class);
  }
}
