java - 由于在应用程序属性中使用占位符，无法构建项目

Question

案例:我想构建稍后可以在 kubernetes 集群 中运行的镜像。在 application.properties 文件中使用占位符来稍后在部署描述中设置这些值似乎很常见。

我的application.properties看起来像这样:

...
spring.datasource.continueOnError=true
spring.datasource.initialization-mode=embedded
catalogservice.baseurl=http://${CATALOG_SERVICE_ADDRESS}:${CATALOG_SERVICE_PORT}
spring.application.name=cartservice
...

我尝试使用

访问这些值

@Value("${catalogservice.baseurl}")
String baseUrl;

当我尝试构建项目时，我收到此异常:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'catalogRequestComponent': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'CATALOG_SERVICE_ADDRESS' in value "http://${CATALOG_SERVICE_ADDRESS}:${CATALOG_SERVICE_PORT}" at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessProperties(AutowiredAnnotationBeanPostProcessor.java:380) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1378) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:575) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:498) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.AbstractBeanFactory.lambda$doGetBean$0(AbstractBeanFactory.java:320) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:222) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:318) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:199) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:846) ~[spring-beans-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:863) ~[spring-context-5.1.2.RELEASE.jar:5.1.2.RELEASE] at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:546) ~[spring-context- ...

我用谷歌搜索了很多，但只找到了ConfigMaps，但这些是为了稍后注入(inject)值。然而，当我创建 kubernetes ConfigMap 时，该项目将无法构建，还是我错了？我希望在创建集群和其他所有内容之前，我需要在第一步创建图像。

我如何传递我的值(value)观

kubernetes 部署脚本的片段:

spec:
      containers:
      - name: myapp
        image: myimage
        ports:
        - containerPort: 8080
        env:
        - name: CATALOG_SERVICE_ADDRESS <--
          valueFrom:
            configMapKeyRef:
              name: catalogmap
              key: catalog-address
       ...

这些值存储在 ConfigMap 中:

apiVersion: v1
kind: ConfigMap
metadata:
  name: catalogmap
data:
  catalog-address: 192.168.178.10

所有功劳均归功于@M。迪努姆

运行mvn install -DskipTests解决了我的所有问题。
