Spring Redis Cache not evicting

The following works (results in the evict being performed):

fooController {
    @ApiEndpoint
    public delete(id) {
        fooService.deleteFoo(id)
    }
}

fooService {
    @CacheEvict(value = "cache1", key = "#id")
    public void deleteFoo(Long id) {
        //delete logic here
    }
}

But this does not work (nothing is evicted from the cache):

fooController {
    @ApiEndpoint
    public delete(name) {
        fooService.deleteFoo2(name)
    }
}

fooService {
    public void deleteFoo2(String name) {
        //delete logic here
        deleteFoo(name.getId())
    }

    @CacheEvict(value = "cache1", key = "#id")
    public void deleteFoo(Long id) {
        //delete logic here
    }
}

Why are my @CacheEvict annotations only called when the method is called straight from the controller?

I'm using Redis as the caching mechanism.

To make spring aspect intercept @Cache* annotations you have to make external call. If you don't like to call this method from another object, use bean self-invocation approach. In this case your class is presented as two objects and one calls the other:

@Resource private FooController thisBean;

public delete(id) {
  thisBean.deleteFoo(id)
}

@CacheEvict(value = "cache1", key = "#id")
public void deleteFoo(Long id) {}

Aop is not worinking when your method is called inside the class. It is working when method is called by another class. So you can define deleteFoo in another service.
