Java jersey 2.6: ContainerRequestFilter: не внутри области запроса

Question

У меня есть сервисное обслуживание на моем tomcat, и он работает правильно, но когда я развертываю его на другом сервере tomcat, он выдает исключение.

Я пытаюсь реализовать ContainerRequestFilter. И это исключение вызвано @Context resourceInfo в моем authenticationFilter (класс, который реализует ContainerRequestFilter). Но я не понимаю, почему и как это исправить. (Я последовал this tutorial)

A MultiException has 3 exceptions. They are: 
1. java.lang.IllegalStateException: Not inside a request scope. 
2. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of services.AuthentificationFilter errors were found 
3. java.lang.IllegalStateException: Unable to perform operation: resolve on services.AuthentificationFilter

Код моего authenticationFilter

@Provider 
public class AuthentificationFilter implements javax.ws.rs.container.ContainerRequestFilter { 

@Context 
private ResourceInfo resourceInfo; 

private static final String AUTHORIZATION = "Authorization"; 
private static final String BASIC = "Basic"; 
private static final Response ACCESS_DENIED = Response.status(Response.Status.UNAUTHORIZED).entity("Essayez de mettre sudo devant votre requete").build(); 
private static final Response ACCESS_FORBIDDEN = Response.status(Response.Status.FORBIDDEN).entity("You shall not pass !").build(); 

@Override 
public void filter(final ContainerRequestContext context) throws IOException { 
    Method method = resourceInfo.getResourceMethod(); 
    if(!method.isAnnotationPresent(PermitAll.class)) { 
     MultivaluedMap<String, String> headers = context.getHeaders(); 
     List<String> authorization = headers.get(AUTHORIZATION); 

     if(method.isAnnotationPresent(DenyAll.class)) { 
      context.abortWith(ACCESS_FORBIDDEN); 
      return; 
     }else if(authorization == null || authorization.isEmpty()) { 
      context.abortWith(ACCESS_DENIED); 
      return; 
     } 

     String encodedUserPassword = authorization.get(0).replaceFirst(BASIC + " ", ""); 
     String auth = new String(Base64.getDecoder().decode(encodedUserPassword.getBytes()));; 

     String[] authTab = auth.split(":"); 
     String username = authTab[0]; 
     String password = authTab[1]; 

     if(method.isAnnotationPresent(RolesAllowed.class)) { 
      RolesAllowed rolesAnnotation = method.getAnnotation(RolesAllowed.class); 
      Set<String> rolesSet = new HashSet<String>(Arrays.asList(rolesAnnotation.value())); 
      if(!isAllowed(username, password, rolesSet)) { 
       context.abortWith(ACCESS_DENIED); 
       return; 
      } 
     } 
    } 
} 

private boolean isAllowed(final String username, final String password, final Set<String> rolesSet) 
{ 
    boolean isAllowed = false; 
    User user; 
    if((user = new UserMapper().get(username, password)) != null) { 
     String role = user.getStatus().toString(); 
     if(rolesSet.contains(role)) 
      isAllowed = true; 
    } 
    return isAllowed; 
} 

} 

Шифр ​​MyApplication.java, который регистрирует фильтр:

public class MyApplication extends ResourceConfig { 

public MyApplication() { 
    packages("services"); 
    register(AuthentificationFilter.class); 
} 
} 

И, наконец, web.xml

</web-app> 

Что я делаю неправильно?

Answer 1

Я наконец нашел решение. Мне пришлось создать класс, который реализует DynamicFeature и зарегистрировать мой AuthenticationFilter благодаря настраиваемому конструктору.

@Provider 
public class AuthenticationDynamicFeature implements DynamicFeature { 

    @Override 
    public void configure(ResourceInfo resourceInfo, FeatureContext featureContext) { 
     featureContext.register(new AuthenticationFilter(resourceInfo)); 
    } 
} 

А вот пользовательский конструктор:

public AuthenticationFilter(ResourceInfo resourceInfo) { 
    super(); 
    this.resourceInfo = resourceInfo; 
} 

Я пробовал много других способов, и это один, это единственный, который работал для меня.
