Spring条件Yaml属性值

Question

这就是我的.yaml属性文件中的一行的样子：

profiles.active: rabbit-${CLUSTER_ENV}, mongo-${CLUSTER_ENV} ...

我只想将以下逻辑用于rabbit-属性：

if(CLUSTER_ENV == "local") {
   return "dev";
} else {
   return CLUSTER_ENV;
}

其他属性应使用local填充，但仅在该位置，应有条件地填充属性值。我可以以某种方式在Spring Yaml属性中添加此逻辑吗？

它看起来不漂亮，但是您可以使用类似以下内容的东西：

 #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}}

基于评论的更新：

 #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}}
