RestClient 错误 javax.ws.rs.WebApplicationException：未知错误，状态码 404

Question

我正在尝试从 Quarkus 的 api 向 Jersey 的 api 请求，但 Jersey API 返回 404 错误：

javax.ws.rs.WebApplicationException：未知错误，状态码 404

看来 quarkus rest 客户端无法识别或无法解析 payload json。

你已经得到类似的东西了吗？

有效载荷应该是这样的：

{
    "code": 404,
    "description": "some description....",
    "label": "API_ERROR_OBJECT_NOT_FOUND",
    "message": "Requested Object not found"
}

代码：

@ApplicationScoped
public class MachineService {

    @Inject
    @RestClient
    ICoreSummaryRest iCoreSummaryRest;

    public Boolean transferDatacollector(ObjectNode transferDatacollector) {
        try {
            String resp = iCoreSummaryRest.updateDataCollectosTransfer
                (transferDatacollector.toString());
            return Boolean.valueOf(resp);
        }catch (Exception e){
            return null;
        }
    }

Answer 1

如果你想阅读正文，你可以捕捉到这样的错误：

try {
  String resourceResponse = errorRestClient.getResource();
} catch (WebApplicationException e) {
  String respStr = e.getResponse().readEntity(String.class);
  LOGGER.error(respStr);
}

这将为http://mockbin.org/bin/3144eda0-9fa7-4893-90ee-5d624d51bcd2 的以下 mockbin 打印此内容

2022-01-30 17:59:45,851 错误 [org.acm.arc.ErrorHTTPrestAPI] （vert.x-eventloop-thread-11）{“描述”：“一些 描述....”， "标签": "API_ERROR_OBJECT_NOT_FOUND", “消息”：“未找到请求的对象”}

我的界面是这样的

@ApplicationScoped
@Path("/")
@RegisterRestClient(baseUri="http://mockbin.org/bin/3144eda0-9fa7-4893-90ee-5d624d51bcd2")
public interface ErrorRestClient {

    @GET
    @Path("")
    String getResource();

}

Answer 2

如果我理解正确这个issue， 当 RestClient 收到一个不同于 2xx 的响应时，它会自动抛出这个异常。

也许您可以禁用 ResponseExceptionMapper 或创建一个拦截器来处理此异常。

下面我只是引用这个issue的答案

这个异常是由默认的rest客户端ResponseExceptionMapper抛出的。

您应该能够通过将以下属性添加到 application.properties 来禁用它：

microprofile.rest.client.disable.default.mapper=false

请参阅 MicroProfile Rest Client 规范的 Default ResponxeExceptionMapper 和 ResponseExceptionMapper 部分。
