Question

我有一个实用程序类：

@RequestScoped
public class StatsServicesDataImpl {
    @Qualifier
    @Retention(RUNTIME)
    @Target({ METHOD, PARAMETER })
    public @interface Lines {
    }

    @Qualifier
    @Retention(RUNTIME)
    @Target({ METHOD, PARAMETER })
    public @interface Versions {
    }

    public StatsServicesDataImpl() {
    }


    @Produces
    @Versions
    @Transactional(TxType.REQUIRES_NEW)
    public String getVersionsAsJsonString() {
        log.debug("CDI calls getVersionsAsJsonString");
    ...
        return json.toString();
    }

    @Produces
    @Lines
    @Transactional(TxType.REQUIRES_NEW)
    public String getLinesAsJsonString() {
        log.debug("CDI calls getLinesAsJsonString");
    ...
        return json.toString();
    }
}

然后是一个JAX-RS类，带有：

@GET
@Path("/versions")
@Produces(MediaType.APPLICATION_JSON)
@Inject
public Response getVersions(@Versions String versions) {
    log.debug("Endpoint versions :" + versions);
    return Response.ok(versions).build();
}

@GET
@Path("/lines")
@Produces(MediaType.APPLICATION_JSON)
@Inject
public Response getLines(@Lines String lines) {
    log.debug("Endpoint lines :" + lines);
    return Response.ok(lines).build();
}

它不能按预期工作:( 我希望当我调用URL行时，CDI获得行（@Inject和@Lines）并拥有JSON。但是当我拨打电话（http://...../lines）时，我得到了：

CDI calls getLinesAsJsonString
Endpoint lines :{"lignes":[{"id":97,"idu":1,"nom":"01"},{"id":98,"idu":2,"nom":"02"},{"id":99,"idu":3,"nom":"03"},{"id":100,"idu":4,"nom":"04"},{"id":101,"idu":5,"nom":"05"}]}
CDI calls getVersionsAsJsonString
Endpoint versions :{"versions":[{"id":71,"vdhId":19,"vdrId":18,"vdpId":18,"vdhNom":"Importé le 2017-08-10 Septembre 2017 V1","vdhDateExp":"Sep 1, 2017 12:00:00 AM","jexDateDeb":"Sep 1, 2017 12:00:00 AM","jexDateFin":"Aug 10, 2018 12:00:00 AM","downloadedDate":"mai 1, 2018"}]}
Endpoint lines :

当我调用版本时：

CDI calls getLinesAsJsonString
Endpoint lines :{"lignes":[{"id":97,"idu":1,"nom":"01"},{"id":98,"idu":2,"nom":"02"},{"id":99,"idu":3,"nom":"03"},{"id":100,"idu":4,"nom":"04"},{"id":101,"idu":5,"nom":"05"}]}
CDI calls getVersionsAsJsonString
Endpoint versions :{"versions":[{"id":71,"vdhId":19,"vdrId":18,"vdpId":18,"vdhNom":"Importé le 2017-08-10 Septembre 2017 V1","vdhDateExp":"Sep 1, 2017 12:00:00 AM","jexDateDeb":"Sep 1, 2017 12:00:00 AM","jexDateFin":"Aug 10, 2018 12:00:00 AM","downloadedDate":"mai 1, 2018"}]}
Endpoint versions :

相同的结果:(好像两个生产者方法都被称为...

有什么想法如何结合JAX-RS和CDI，以便我可以在Rest-request的响应中注入请求的结果（由CDI生成）？

是否可以在JAX-RS请求中注入生产者方法的结果？
