Spring cache @Cacheable method ignored when called from within the same class
caching, spring, spring-cache
Solution
This is because of the way proxies are created for handling caching, transaction related functionality in Spring. This is a very good reference of how Spring handles it - Transactions, Caching and AOP: understanding proxy usage in Spring
In short, a self call bypasses the dynamic proxy and any cross cutting concern like caching, transaction etc which is part of the dynamic proxies logic is also bypassed.
The fix is to use AspectJ compile time or load time weaving.
Problem
I'm trying to call a `@Cacheable` method from within the same class: ``` @Cacheable(value = "defaultCache", key = "#id") public Person findPerson(int id) { return getSession().getPerson(id); } public List<Person> findPersons(int[] ids) { List<Person> list = new ArrayList<Person>(); for (int id : ids) { list.add(findPerson(id)); } return list; } ``` and hoping that the results from `findPersons` are cached as well, but the `@Cacheable` annotation is ignored, and `findPerson` method got executed everytime. Am I doing something wrong here, or this is intended?
