QUKUS GraalVM URLConnection的奇怪行为

Question

我正在测试旅行应用程序的Quarkus功能，当我尝试建立在基于Quarkus的GraalVM应用程序中运行的URLConnection时，我发现了一个奇怪的行为。如果我运行原生应用程序：

./target/getting-started-1.0.0-SNAPSHOT-runner

我调用RESTendpoint：

curl 'http://localhost:8080/api/v1/covid-restrictions'

然后我收到以下错误：

2022-06-01 17:38:43,844 ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-0) HTTP Request to /api/v1/covid-restrictions failed, error id: f6130b71-c9fb-4a67-a996-c58fba695117-1: com.amadeus.exceptions.NetworkException: [---]

但是，当我运行与Jar相同的应用程序时，一切都很好。

java -jar target/quarkus-app/quarkus-run.jar

这里有一个看到错误的例子：

我是否需要以某种方式为GraalVM配置Quarkus应用程序？

如果有帮助，我会分享整个StackTrace：

与当今大多数 API 一样，艾玛迪斯库仅支持 HTTPS。
对于纯模式下的Quarkus，您需要在 src/主/资源/应用程序属性中显式启用 SSL（某些扩展除外，请参阅下面的链接）。

java prettyprint-override">quarkus.ssl.native=true

看见https://quarkus.io/guides/native-and-ssl

添加此属性后，您将得到不同的运行时错误：

2022-06-02 00:45:25,381 ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-0) HTTP Request to /api/v1/covid-restrictions failed, error id: 6d821ce1-23fd-4d88-8f63-992b6453830a-1: com.oracle.svm.core.jdk.UnsupportedFeatureError: Code that was considered unreachable by closed-world analysis was reached.

尝试注册以下反射类（DiseaseAreaReport和所有内部类），因为Amadeus将使用GSON，因此也使用Java反射将JSON字符串数据应用于DiseaseAreReport POJO。https://quarkus.io/guides/writing-native-applications-tips#registering-反省

package org.acme;

import io.quarkus.runtime.annotations.RegisterForReflection;

@RegisterForReflection(targets = {
        com.amadeus.Amadeus.class,
        com.amadeus.HTTPClient.class,
        com.amadeus.Params.class,
        com.amadeus.Response.class,
        com.amadeus.client.AccessToken.class,
        com.amadeus.dutyOfCare.diseases.Covid19AreaReport.class,
        com.amadeus.exceptions.ResponseException.class,
        // com.amadeus.resources.DiseaseAreaReport and all inner classes
        com.amadeus.resources.DiseaseAreaReport.class,
        com.amadeus.resources.DiseaseAreaReport.Area.class,
        com.amadeus.resources.DiseaseAreaReport.AreaAccessRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.AreaPolicy.class,
        com.amadeus.resources.DiseaseAreaReport.AreaRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.AreaVaccinated.class,
        com.amadeus.resources.DiseaseAreaReport.Border.class,
        com.amadeus.resources.DiseaseAreaReport.DatedInformation.class,
        com.amadeus.resources.DiseaseAreaReport.DatedQuarantineRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.DatedTracingApplicationRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.DeclarationDocuments.class,
        com.amadeus.resources.DiseaseAreaReport.DiseaseCase.class,
        com.amadeus.resources.DiseaseAreaReport.DiseaseInfection.class,
        com.amadeus.resources.DiseaseAreaReport.DiseaseTestingRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.DiseaseVaccination.class,
        com.amadeus.resources.DiseaseAreaReport.EntryRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.ExitRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.GeoCode.class,
        com.amadeus.resources.DiseaseAreaReport.Link.class,
        com.amadeus.resources.DiseaseAreaReport.MaskRestriction.class,
        com.amadeus.resources.DiseaseAreaReport.Sources.class,
        com.amadeus.resources.DiseaseAreaReport.Transportation.class,
        com.amadeus.resources.DiseaseAreaReport.ValidityPeriod.class,
        com.amadeus.resources.Resource.class
})
public class AmadeusReflection {

}

我希望这解决了这个问题，如果不是更深入地挖掘，那么哪些类或内部类缺少注册，以便使用调试器或跟踪堆栈跟踪进行反射。

P、 S.您的测试显示以下警告：

[WARNING] [io.quarkus.resteasy.reactive.server.deployment.QuarkusServerEndpointIndexer] Quarkus detected the use of JSON in JAX-RS method 'org.acme.CovidResource#hello' but no JSON extension has been added. Consider adding 'quarkus-resteasy-reactive-jackson' or 'quarkus-resteasy-reactive-jsonb'.
