在 docker 容器中启动项目时找不到 io.jsonwebtoken.impl.DefaultJwtBuilder

Question

当在本地启动我的 Quarkus 项目时，mvn quarkus:dev执行使用 JJWT 的函数时没有错误。但是，当我将项目导出到 docker 容器时，它给我一个错误，指出它找不到 DefaultJwtBuilder。

当对我的项目进行 dockerizing 时，我首先执行

./mvnw package -Pnative -Dquarkus.native.container-build=true

如Quarkus 文档中所述，用于在不使用 GraalVM 的情况下创建 Linux 可执行文件。

其次是

docker build -f src/main/docker/Dockerfile.native -t quarkus-quickstart/getting-started .

当使用 Docker Desktop 启动项目时，出现错误。

我的 pom.xml 中的依赖项如下。

<dependency>
  <groupId>io.jsonwebtoken</groupId>
  <artifactId>jjwt-api</artifactId>
  <version>0.11.2</version>
</dependency>
<dependency>
  <groupId>io.jsonwebtoken</groupId>
  <artifactId>jjwt-impl</artifactId>
  <version>0.11.2</version>
  <scope>runtime</scope>
</dependency>
<dependency>
  <groupId>io.jsonwebtoken</groupId>
  <artifactId>jjwt-jackson</artifactId>
  <version>0.11.2</version>
  <scope>runtime</scope>
</dependency>

详细的错误信息是

io.jsonwebtoken.lang.UnknownClassException: Unable to load class named [io.jsonwebtoken.impl.DefaultJwtBuilder] from the thread context, current, or system/application ClassLoaders. All heuristics have been exhausted. Class could not be found. Have you remembered to include the jjwt-impl.jar in your runtime classpath?

我用来构建 docker 镜像的 dockerfile 是

## Stage 1 : build with maven builder image with native capabilities
FROM quay.io/quarkus/centos-quarkus-maven:20.2.0-java11 AS build
COPY pom.xml /usr/src/app/
RUN mvn -f /usr/src/app/pom.xml -B de.qaware.maven:go-offline-maven-plugin:1.2.5:resolve-dependencies
COPY src /usr/src/app/src
USER root
RUN chown -R quarkus /usr/src/app
USER quarkus
RUN mvn -f /usr/src/app/pom.xml -Pnative clean package

## Stage 2 : create the docker final image
FROM registry.access.redhat.com/ubi8/ubi-minimal
WORKDIR /work/
COPY --from=build /usr/src/app/target/*-runner /work/application

# set up permissions for user `1001`
RUN chmod 775 /work /work/application \
  && chown -R 1001 /work \
  && chmod -R "g+rwX" /work \
  && chown -R 1001:root /work

EXPOSE 8000
USER 1001

CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]

任何帮助将不胜感激。

这不起作用，因为需要导入 jjwt-impl .jar

使用

    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-api</artifactId>
        <version>0.11.5</version>
    </dependency>
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-impl</artifactId>
        <version>0.11.5</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-jackson</artifactId>
        <version>0.11.5</version>
        <scope>runtime</scope>
    </dependency>
