Spring caching - do not cache in case of error

Question

I am using spring caching, my question is:

How can I control the caching in case the result is an error and the next request could be good?

example:

@Cacheable("mycache")
public  ResponceBO getBigObject(String id) throws Exception {

    boolean isError = false;

    ***   load big object from other service,  can be loaded with errors  ***
    isError = true;

    if(error){
       responceBO.setError(true);
    }

    return responceBO;
}

In case of an error I don't want to cache the object, what can I do instead?

Answer 1

I would suggest reading the conditional caching section of the reference guide. Basically simply specify a unless expression to prevent the caching. (The result placeholder is only available for the unless statement not the condition statement.

@Cacheable("mycache", unless="#result.error")
public  ResponceBO getBigObject(String id) throws Exception { ... }

Should do the trick.
