I want to read spring properties file that has a map of maps

I want to have a property like below that is a map of maps

propertymap = {
    key1:'{subkey1:'subvalue1',subkey2:'subvalue2'}',
    key2:'{subkey3:'subvalue3',subkey4:'subvalue4'}' }

@Value("#{${propertymap}}")  
private Map<String,Map<String,String>> propertymap;

used code like above in my config class but got error. please let me know if there is a way to do this.

I found the way, I had to just remove the ' after the key

propertymap = {  
   key1:{  
      subkey1:'subvalue1',
      subkey2:'subvalue2'
   },
   key2:{  
      subkey3:'subvalue3',
      subkey4:'subvalue4'
   }
}

and below code picks it up

@Value("#{${propertymap}}")  
private Map<String,Map<String,String>> propertymap;
