java - OSGi 中的身份验证过滤器？

Question

我遵循本教程Best practice for REST token-based authentication with JAX-RS and Jersey我在过滤器部分。

我正在使用 OSGI，但我不知道如何注册我的过滤器。我创建了过滤器并构建了我的项目，没有出现任何错误。我在 karaf 中部署了我的包，但我的 @Secured 服务不安全，因为未调用过滤器...

我应该在激活器中添加过滤器吗？在蓝图中？ (我是 osgi 世界的新手)

这是我的过滤器:

@Secured
@Provider
@Priority(Priorities.AUTHENTICATION)
public class AuthenticationFilter implements ContainerRequestFilter {
    private static Logger LOGGER = LoggerFactory.getLogger(AuthenticationFilter.class);
    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {
        LOGGER.info("[AuthenticationFilter] started");
        // Get the HTTP Authorization header from the request
        String authorizationHeader = 
            requestContext.getHeaderString(HttpHeaders.AUTHORIZATION);

        // Check if the HTTP Authorization header is present and formatted correctly 
        if (authorizationHeader == null || !authorizationHeader.startsWith("Bearer ")) {
            throw new NotAuthorizedException("Authorization header must be provided");
        }

        // Extract the token from the HTTP Authorization header
        String token = authorizationHeader.substring("Bearer".length()).trim();

        try {
            // Validate the token
            validateToken(token);
        } catch (Exception e) {
            requestContext.abortWith(Response.status(Response.Status.UNAUTHORIZED).build());
        }
        LOGGER.info("[AuthenticationFilter] ended");
    }

    //TODO: add the key in properties
    //TODO: check the username in DB
    private void validateToken(String token) throws Exception {
        // Check if it was issued by the server and if it's not expired
        // Throw an Exception if the token is invalid
        String username = Jwts.parser()
            .setSigningKey("jeSuisLaSecretPhrase,1234,ilFaudraMePlacerEnConf,Merci")
            .parseClaimsJws(token)
            .getBody()
            .getIssuer();
        if(!"admin".equals(username)){
            throw new NotAuthorizedException("bad token");
        }

    }
}

Karaf 无法加载“http://cxf.apache.org/blueprint/jaxrs”这是我的蓝图:

尝试添加过滤器，如 CXF JAX-RS filter 中所述。文档。

...
<jaxrs:providers>
  <ref bean="authorizationFilter" />
</jaxrs:providers>
...
<bean id="authorizationFilter" class="com....AuthenticationFilter">
