Spring 条件 yaml 属性值

Question

.yaml这就是我的属性文件的一行：profiles.active: rabbit-${CLUSTER_ENV}, mongo-${CLUSTER_ENV} ...我只想为rabbit-属性添加以下逻辑：if(CLUSTER_ENV == "local") {   return "dev";} else {   return CLUSTER_ENV;}应该填充其他属性，local但只有在这个地方应该有条件地填充属性值。我可以以某种方式在 Spring yaml 属性中添加这个逻辑吗？

Answer 1

它看起来不漂亮，但你可以使用类似的东西：

 #this can be added on startup

mykey: key1

#a map with your condition

mymap:

  key1: val1

  key2: val2

#your value based on the condition

conditional: con-${mymap.${mykey}}

问候， WiPU

根据评论更新：

 #this can be added on startup as variable

mykey: local

#a map with your condition

mymap:

  local: dev

  xyz: test

# your value based on the condition or the key as fallback if the key is not 

# present in mymap.

conditional: con-${mymap.${mykey}:${mykey}
