Configuración en TomEE

La clase MoviesMPJWTConfigurationProvider.java proporciona a TomEE la configuración necesaria para la validación JWT.

package org.superbiz.moviefun.rest;

import org.apache.tomee.microprofile.jwt.config.JWTAuthContextInfo;

import jakarta.enterprise.context.Dependent;
import jakarta.enterprise.inject.Produces;
import java.security.KeyFactory;
import java.security.NoSuchAlgorithmException;
import java.security.interfaces.RSAPublicKey;
import java.security.spec.InvalidKeySpecException;
import java.security.spec.X509EncodedKeySpec;
import java.util.Base64;
import java.util.Optional;

@Dependent
public class MoviesMPJWTConfigurationProvider {

    @Produces
    Optional<JWTAuthContextInfo> getOptionalContextInfo() throws NoSuchAlgorithmException, InvalidKeySpecException {
        JWTAuthContextInfo contextInfo = new JWTAuthContextInfo();

        // todo use MP Config to load the configuration
        contextInfo.setIssuedBy("https://server.example.com");

        final String pemEncoded = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlivFI8qB4D0y2jy0CfEq" +
                "Fyy46R0o7S8TKpsx5xbHKoU1VWg6QkQm+ntyIv1p4kE1sPEQO73+HY8+Bzs75XwR" +
                "TYL1BmR1w8J5hmjVWjc6R2BTBGAYRPFRhor3kpM6ni2SPmNNhurEAHw7TaqszP5e" +
                "UF/F9+KEBWkwVta+PZ37bwqSE4sCb1soZFrVz/UT/LF4tYpuVYt3YbqToZ3pZOZ9" +
                "AX2o1GCG3xwOjkc4x0W7ezbQZdC9iftPxVHR8irOijJRRjcPDtA6vPKpzLl6CyYn" +
                "sIYPd99ltwxTHjr3npfv/3Lw50bAkbT4HeLFxTx4flEoZLKO/g0bAoV2uqBhkA9x" +
                "nQIDAQAB";
        byte[] encodedBytes = Base64.getDecoder().decode(pemEncoded);

        final X509EncodedKeySpec spec = new X509EncodedKeySpec(encodedBytes);
        final KeyFactory kf = KeyFactory.getInstance("RSA");
        final RSAPublicKey pk = (RSAPublicKey) kf.generatePublic(spec);

        contextInfo.setSignerKey(pk);

        return Optional.of(contextInfo);
    }

    @Produces
    JWTAuthContextInfo getContextInfo() throws InvalidKeySpecException, NoSuchAlgorithmException {
        return getOptionalContextInfo().get();
    }
}

Utilizando MicroProfile JWT en TomEE

El recurso JAX-RS MoviesRest.java contiene varios puntos finales seguros, que se consiguen mediante el uso de anotación estándar @RolesAllowed. MicroProfile JWT se encarga de realizar la validación de las solicitudes entrantes con el encabezado Authorization que proveen un Access Token firmado

   package org.superbiz.moviefun.rest;

   import org.superbiz.moviefun.Movie;
   import org.superbiz.moviefun.MoviesBean;

   import jakarta.annotation.security.RolesAllowed;
   import jakarta.inject.Inject;
   import jakarta.ws.rs.*;
   import jakarta.ws.rs.core.MediaType;
   import java.util.List;

   @Path("cinema")
   @Produces(MediaType.APPLICATION_JSON)
   @Consumes(MediaType.APPLICATION_JSON)
   public class MoviesRest {

       @Inject
       private MoviesBean moviesBean;

       @GET
       @Produces(MediaType.TEXT_PLAIN)
       public String status() {
           return "ok";
       }

       @GET
       @Path("/movies")
       @RolesAllowed({"crud", "read-only"})
       public List<Movie> getListOfMovies() {
           return moviesBean.getMovies();
       }

       @GET
       @Path("/movies/{id}")
       @RolesAllowed({"crud", "read-only"})
       public Movie getMovie(@PathParam("id") int id) {
           return moviesBean.getMovie(id);
       }

       @POST
       @Path("/movies")
       @RolesAllowed("crud")
       public void addMovie(Movie newMovie) {
           moviesBean.addMovie(newMovie);
       }

       @DELETE
       @Path("/movies/{id}")
       @RolesAllowed("crud")
       public void deleteMovie(@PathParam("id") int id) {
           moviesBean.deleteMovie(id);
       }

       @PUT
       @Path("/movies")
       @RolesAllowed("crud")
       public void updateMovie(Movie updatedMovie) {
           moviesBean.updateMovie(updatedMovie);
       }

   }

 @Inject
 @ConfigProperty(name = "java.runtime.version")
 private String javaVersion;

Sobre la arquitectura de prueba

Los casos de prueba de este proyecto se construyen con Arquillian. La configuración arquillian se puede encontrar en src/test/resources/arquillian.xml

La clase TokenUtils.java se utiliza durante la prueba para actuar como un servidor de Autorización que genera Access Tokens basados en los archivos de configuración privateKey.pem, ` publicKey.pem`, Token1.json y ` Token2 .json`.

nimbus-jose-jwt es la libreria utilizada para la generación de JWT durante las pruebas.

Token1.json

{
    "iss": "https://server.example.com",
    "jti": "a-123",
    "sub": "24400320",
    "upn": "jdoe@example.com",
    "preferred_username": "jdoe",
    "aud": "s6BhdRkqt3",
    "exp": 1311281970,
    "iat": 1311280970,
    "auth_time": 1311280969,
    "groups": [
        "group1",
        "group2",
        "crud",
        "read-only"
    ]
}

Token2.json

{
  "iss": "https://server.example.com",
  "jti": "a-123",
  "sub": "24400320",
  "upn": "alice@example.com",
  "preferred_username": "alice",
  "aud": "s6BhdRkqt3",
  "exp": 1311281970,
  "iat": 1311280970,
  "auth_time": 1311280969,
  "groups": [
    "read-only"
  ]
}
