quarkus-arc Unsatisfied dependency problem

Question

This is my resource class: with repository injection.

@Path("/posts")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class PostsResource {


    @Context
    UriInfo uriInfo;

    @Inject
    PostRepository posts;

    @GET
    public Response getAllPosts(
        @QueryParam("q") String q,
        @QueryParam("limit") @DefaultValue("10") int limit,
        @QueryParam("offset") @DefaultValue("0") int offset
    ) {
        return Response.ok(this.posts.findByKeyword(q, limit, offset)).build();
    }

    @GET
    @Path("/count")
    public Response getAllPosts(@QueryParam("q") String q) {
        return Response.ok(
            Count.builder().count(this.posts.countByKeyword(q))
        ).build();
    }

    @POST
    public Response savePost(PostForm post) {
        Post entity = Post.builder()
            .title(post.getTitle())
            .content(post.getContent())
            .build();
        Post saved = this.posts.save(entity);
        return Response.created(uriInfo.getBaseUriBuilder().path("/posts/{slug}").build(saved.getSlug())).build();
    }

}

and repository class

public class PostRepository extends AbstractRepository<Post, Long> {

    @Inject
    private EntityManager em;

    @Transactional
    public List<Post> findByKeyword(String keyword, long limit, long offset) {
        return this.stream()
                .filter(p -> Optional.ofNullable(keyword)
                        .map(k -> p.getTitle().contains(k) || p.getContent().contains(k)).orElse(true))
        
                .limit(limit).skip(offset).collect(toList());
    }

    @Transactional
    public long countByKeyword(String keyword) {
        return this.stream().filter(p -> Optional.ofNullable(keyword)
                .map(k -> p.getTitle().contains(k) || p.getContent().contains(k)).orElse(true)).count();
    }

    @Transactional
    public List<Post> findByCreatedBy(String username) {
        Objects.requireNonNull(username, "username can not be null");

        return this.stream().filter(p -> username.equals(p.getCreatedBy().getUsername()))
                .sorted(Post.DEFAULT_COMPARATOR).collect(toList());
    }

    @Transactional
    public Optional<Post> findBySlug(String slug) {
        Objects.requireNonNull(slug, "Slug can not be null");
        return this.stream().filter(p -> p.getSlug().equals(slug)).findFirst();
    }

    public List<Post> findAll() {
        return em.createNamedQuery("Post.findAll", Post.class).getResultList();

    }

    public Post findPostById(Long id) {

        Post post = em.find(Post.class, id);

        if (post == null) {
            throw new WebApplicationException("Post with id of " + id + " does not exist.", 404);
        }
        return post;
    }

    @Transactional
    public void updatePost(Post post) {

        Post postToUpdate = findPostById(post.getId());
        postToUpdate.setTitle(post.getTitle());
        postToUpdate.setContent(post.getContent());
    }

    @Transactional
    public void createPost(Post post) {

        em.persist(post);

    }

    @Transactional
    public void deletePost(Long postId) {

        Post p = findPostById(postId);
        em.remove(p);

    }

    @Override
    protected EntityManager entityManager() {
        return this.em;
    }

}

I cannot build this beacause the build return :

Unsatisfied dependency for type com.ciwara.kalanSowApp.repository.PostRepository and qualifiers [@Default]

       - java member: com.ciwara.kalanSowApp.rest.post.PostsResource#posts

       - declared on CLASS bean [types=[com.ciwara.kalanSowApp.rest.post.PostsResource], qualifiers=[@Default, @Any], target=com.ciwara.kalanSowApp.rest.post.PostsResource]

Answer 1

Above the Injected client also add @RestClient and to client class @RegisterRestClient, @ApplicationScoped. Like this

@Path("/posts")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@RegisterRestClient
@ApplicationScoped
public class PostsResource {}

//Where you inject.
@Inject
@RestClient
PostRepository posts;

Answer 2

In order to make PostRepository injectable, it must be a bean. The most common way to declare a class as bean is to add a Bean-Scope annotation to the class.

In the given class, adding @ApplicationScoped seems sensible.
