You must set the nullValue of the PropertyPlaceholderConfigurer. In general you should avoid field injection, or at least try and only use one type of injection per class. First check if your property file is loaded, Normally beginning of your output log, you should see name of the property file. And then configure following bean in one of your configuration file, if not already done.

Then use the way you are doing, It should resolve that property. And make sure that, TaskService bean is actually loaded component scan package should includes this class. Although i normally use above way, there is another way, you may need to check just fyi, above should work.

Quite often the problem is that the field injection is finished after the constructor has finished. That means you can access the value that was injected with Value only after that.

If a method getAA ist added to TaskService:. You code can't work because Spring needs to first create instance of class call the constructor and THEN inject values to the fields. It is because you don't define a constructor with aa as argument, neither does the class have a setter, so there is no way to inject it.
