Quarkus + 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。 如果我运行本机应用程序：

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

我调用 REST 端点：

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

在此处查看错误的一个示例：

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：

提前谢谢了。

与当今的大多数 API 一样，Amadeus 库仅支持 HTTPS。
对于原生模式的 Quarkus，您需要在src/main/resources/application.properties中显式启用 SSL（某些扩展除外，请参见下面的链接）。

quarkus.ssl.native=true

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

添加此属性后，您将收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 ，因此还会使用 Java 反射将 JSON 字符串数据应用到 DiseaseAreaReport POJO。 https://quarkus.io/guides/writing-native-applications-tips#registering-for-reflection

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 {

}

我希望这可以解决这个问题，如果不深入挖掘哪些类或内部类缺少注册以使用调试器进行反射或跟踪堆栈跟踪。

PS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'.

考虑在pom.xml中添加 RESTEasy Reactive Jackson 扩展：
