RESTClient 3.5 WizTools、POST 方法、新数据集

Question

我正在将 WizTools.org RESTClient 3.5 用于学校项目。 我已经写了一些 HTTP 方法。 GET 和 DELETE 运行良好。我还写了一个 POST 和一个 PUT，但不知道如何使用 restclient 执行它们。我尝试将 JSON 数据集作为字符串正文插入，但它显示 415（不支持的媒体类型）。这是您插入新数据集的方式吗？我该怎么做？

感谢您的帮助！

这是我的 POST 方法：

@POST
@Consumes({ APPLICATION_JSON, APPLICATION_XML, TEXT_XML })
@Produces
public Response createArtikel(@Valid Artikel artikel, @Context UriInfo uriInfo) {
    artikel.setId(KEINE_ID);

    final Artikel result = artikelBroker.createArtikel(artikel);
    if (LOGGER.isLoggable(FINEST)) {
        LOGGER.finest(result.toString());
    }

    return Response.created(getUriArtikel(result, uriInfo))
                   .build();
}

这里是 createArtikel 方法：

public Artikel createArtikel(Artikel artikel) {
    if (artikel == null) {
        return null;
    }

    em.persist(artikel);
    return artikel;     
}

您需要明确说明您的服务正在生成 json，因此只需在 @Produces 注释中提供 APPLICATION_JSON。
