SpringBoot 2.1.4.RELEASE not to cache null value in @Cacheable annotation

Question

I have an SpringBoot 2.1.4.RELEASE app. with a repository:

@Repository
public interface PercentageAlertXMenuRepository extends CrudRepository<PercentageAlertXMenu, Long> {

    @Cacheable("percentageAlertXMenu", unless="#result == null")
    PercentageAlertXMenu findByPercentageAlertAndMenu (MenuPercentageAlert percentageAlert, Menu Menu);

but I got a compilation error:

Syntax error on token ""percentageAlertXMenu"", invalid 
 MemberValuePairs

Answer 1

You need to use the value attribute of the annotation:

@Cacheable(value="percentageAlertXMenu", unless="#result == null")
