Java 如何在YAML文件（spring）中定义动态键

我需要更改其中一个模块的超时。以下是application.yml的一部分：

zuul:
  servlet-path: /zuul-servlet
  headers: Cache-Control
  ignoredServices: "*"
  addProxyHeaders: false
  routes:
    audit:
      path: /audit/**
      serviceId: ${eureka.registration.client.prefix}-audit
      stripPrefix: false
      sensitiveHeaders: ''
    auth:
      path: /auth/**
      serviceId: ${eureka.registration.client.prefix}-auth
      stripPrefix: false
      sensitiveHeaders: ''


ribbon:
  ReadTimeout: 30000
  serverListRefreshInterval: 10
  
hystrix:
  command:
    default:
      circuitBreaker.enabled: false
      execution.isolation.thread.timeoutInMilliseconds: 30000

我可以通过按serviceId添加特定模块的配置来实现这一点。当我硬编码serviceId时，它可以工作，但它是动态的：

${eureka.registration.client.prefix}-audit

hystrix:
  command:
    default:
      circuitBreaker.enabled: false
      execution.isolation.thread.timeoutInMilliseconds: 30000
    ${eureka.registration.client.prefix}-audit:
      circuitBreaker.enabled: false
      execution.isolation.thread.timeoutInMilliseconds: 70000  
      
${eureka.registration.client.prefix}-audit:
  ribbon:
    ReadTimeout: 70000
    serverListRefreshInterval: 10

${eureka.registration.client.prefix}-audit

不能作为密钥使用
