我使用Jib生成Spring Boot 映像并将其推送到DockerHub

mvn compile jib:build

pom包含参考：

<resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>application.properties</include>
                <include>languages.json</include>
            </includes>
        </resource>
    </resources>

然后我使用 docker-compose differentes 容器打包并运行

javaws:
    container_name: javaws
    image: myJavaWS:latest
    environment:
        - SPRING_PROFILES_ACTIVE=${ENV}
        - SPRING_CONFIG_LOCATION=${JAVA_WS_ENV_PROP_FILE}
    expose:
        - ${JAVA_WS_PORT}
    ports:
        - 9000:9000
    links:
        - my-db
    depends_on:
        - my-db
    volumes:
        - "/root/DOCKER/config:/config"
        - ${FS_FILE_PATH}:/root/path

在 docker-compose 中，我也设置了application-.yml和 Spring 活动配置文件以使用

JAVA_WS_ENV_PROP_FILE=file:/config/application-WSTEST.yml

.jar 还有一个application.properties文件；泊坞窗图像也是；

项目树

info.app.description=My WS
info.app.name=My java WS
info.app.version=@project.version@

从DockerHub下载图像后，我会在图像内部验证该文件是否存在！

应用程序运行失败，因为 application.properties 中的属性尚未解析。

控制器端点是：

@Configuration
public class SwaggerOASConfig {

@Bean
public OpenAPI springShopOpenAPI(
        @Value("${info.app.name}") String appName,
        @Value("${info.app.version:unknow}") String appVersion) {
    return new OpenAPI()

根据上面的评论，根本原因似乎是您SPRING_CONFIG_LOCATION在 docker-compose 设置中的自定义覆盖了默认设置，从而阻止您的应用程序查看其他位置，包括/app/resources/application.properties.
