正如标题所示，我正在尝试使用 Docker 为基于 Kotlin 的 Micronaut 应用程序构建 native 镜像。
我已将以下依赖项添加到我的 build.gradle 文件中。
compileOnly 'org.graalvm.nativeimage:svm'
annotationProcessor 'io.micronaut:micronaut-graal'
我的 Dockerfile 如下所示。
FROM oracle/graalvm-ce:20.1.0-java11 as graalvm
RUN gu install native-image
WORKDIR /src
COPY . /src
RUN ./gradlew assemble
RUN native-image --no-server -cp build/libs/*-all.jar dk.fitfit.injurylog.Application
FROM frolvlad/alpine-glibc
RUN apk update && apk add libstdc++
COPY --from=graalvm /src/dk.fitfit.injurylog.application /app/app
ENTRYPOINT ["/app/app"]
一切似乎都井然有序。图像启动并似乎接受连接，但是当我发起 http 请求时，会发生以下错误。

关于如何避免上述错误的任何线索？
最佳答案
我未能使用 @Introspected 注释我的实体之一。
关于docker - 为 micronaut 应用程序构建 native 镜像，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/62102818/
