【问题描述】：
我目前正在尝试对具有 2 个配置文件的 Spring Boot 应用程序进行 docker 化：
application-dev.yml 和 application-prod.yml
当我在我的机器上运行该应用程序时，它可以工作，但是当我尝试 dockerize 时，它无法从所述文件中读取。它不会将变量加载到@Value注解中，即使服务端口是错误的。

这是我的 dockerfile：
FROM maven:3-jdk-11 AS builder
RUN mkdir -p /usr/local/backend
RUN chmod 777 /usr/local/backend/
ADD settings.xml /root/.m2/
COPY settings.xml /usr/share/maven/ref/
COPY pom.xml /usr/share/maven/ref/repository
COPY . /usr/local/backend
WORKDIR /usr/local/backend
RUN mvn clean generate-sources package
FROM openjdk:11
COPY --from=builder /usr/local/backend/target/service-userinfosearch.jar /usr/local/backend/
RUN chmod 777 /usr/local/backend/
WORKDIR /usr/local/backend
ENTRYPOINT ["java", "-jar", "service-userinfosearch.jar","-Dspring.profiles.active=dev"]
我正在使用这个命令构建：
docker build . -t userinfosearch/v1
和这个一起运行：
docker run --rm --name version1 -p 8082:8082 userinfosearch/v1
