I am working with redis cache. I have in my code
Where the time is hardcoded
@RedisHash(timeToLive=60)
In applications.yml File I would like to add the following
throttle:
cache:
rate: 60
So I can have the following
@RedisHash(timeToLive="${throttle.cache.rate}")
But this failed with Type mismatch cannot convert from String to Long. So I tried
@RedisHash(timeToLive="#{new Long(}'${throttle.cache.rate}')")
But still failing with Type mismatch cannot convert from String to Long.
CodePudding user response:
Basically, that is not possible. Why? Because the value for an annotation must be a compile-time constant. All the compiler knows at compile time is that you are passing a String
to a property that only accepts long
.
It will only be a long
when you run your Spring application but that is too late because the compiler does not know that.
