Kubernetes中Quartz配置文件无法读取环境变量问题

我有一个部署在Kubernetes中的Spring Boot应用，集成了Quartz调度组件。为满足多环境部署需求，已将quartz.properties存入ConfigMap实现环境隔离。

目前计划将所有密码存储到环境变量中，这种方式在Spring的application.properties中可以正常生效，但在quartz.properties里无法实现变量替换。

我参考方案使用以下格式：

org.quartz.dataSource.quartzDS.user=$@MY_ENV_VARIABLE
org.quartz.dataSource.quartzDS.password=$@MY_OTHER_ENV_VARIABLE

该配置在本地Windows环境正常工作，但部署到Kubernetes（基于Ubuntu镜像）后，变量被当作字面量$@MY_ENV_VARIABLE处理。目前仅能考虑在部署流水线中通过文本替换注入明文密码，但希望实现与本地一致的效果。

补充说明：已尝试以下格式，服务器端均无效：

${MY_ENV_VARIABLE}
$@MY_ENV_VARIABLE (本地PC有效)
$\@MY_ENV_VARIABLE
"$@MY_ENV_VARIABLE"

补充配置：
configmap.yml:

kind: ConfigMap
apiVersion: v1
metadata:
  name: my-configmap
data:
  application.properties: |-
    {{- .Files.Get "config-maps/application.properties" | nindent 8 }}

  myapp.properties: |-
    {{- .Files.Get "config-maps/myapp.properties" | nindent 8 }}

  logback-spring.xml: |-

    {{- .Files.Get "config-maps/quartz.properties" | nindent 8 -}}
