Question

构建本地quarkus图像时出现问题，尝试使用mongo panache查询。如果我使用开发人员配置文件或构建普通的jar，则一切正常。

这是我的Dockerfile.native

query = """SELECT stuff FROM TABLE WHERE name LIKE '%%(this_name)s%'"""
results = pd.read_sql(query, con=cnx, params={'this_name': some_name})


## Stage 1 : build with maven builder image with native capabilities
FROM quay.io/quarkus/centos-quarkus-maven:19.2.1 AS build
COPY backend /usr/src/app/backend
COPY frontend /usr/src/app/frontend
COPY pom.xml /usr/src/app/
USER root
RUN chown -R quarkus /usr/src/app
USER quarkus
RUN cd /usr/src/app/ && mvn clean package -Pnative -Dnative-image.xmx=4g
RUN mkdir -p /tmp/ssl-libs/lib \
  && cp /opt/graalvm/jre/lib/security/cacerts /tmp/ssl-libs \
  && cp /opt/graalvm/jre/lib/amd64/libsunec.so /tmp/ssl-libs/lib/

## Stage 2 : create the docker final image
FROM registry.access.redhat.com/ubi8/ubi-minimal
WORKDIR /work/
COPY --from=build /usr/src/app/backend/target/*-runner /work/application
COPY --from=build /tmp/ssl-libs/ /work/
RUN chmod 775 /work
EXPOSE 8080
CMD ["./application", "-Dquarkus.http.host=0.0.0.0", "-Djava.library.path=/work/lib", "-Djavax.net.ssl.trustStore=/work/cacerts"]

有人有类似的问题吗？

存储库

@MongoEntity(collection = "Budget")
public class Budget {

    private ObjectId id;
    private Period period;
    private List<Category> categories;

    public Budget() {
        period = new Period();

        categories = new ArrayList<>();
    }

//business method getter setters...

}

控制器

@ApplicationScoped
public class BudgetRepository implements PanacheMongoRepository<Budget> {

}

GraalVM本机映像需要知道需要通过关联才能访问的类。由于您的REST端点使用Response返回类型，因此Quarkus无法自动获取Budget类的反射，因此您需要为此使用@RegisterFroReflection批注。

有一个PR可以为您完成任务，因此您很快将不再需要自己做：https://github.com/quarkusio/quarkus/pull/6326/files

但是只要不合并，就需要在@RegisterFroReflection类上添加Budget注释。
