How can I clear multiple caches using JCache annotation @CacheRemoveAll?

Question

I have a method who's execution should clear two caches in my Spring+JCache+ehcache 3.5 project.

I tried:

@CacheRemoveAll(cacheName = "cache1")
@CacheRemoveAll(cacheName = "cache2")
public void methodToBeCalled(){
}

and

@CacheRemoveAll(cacheName = "cache1", cacheName = "cache2")
public void methodToBeCalled(){
}

In the first I get:

Duplicate annotation of non-repeatable type @CacheRemoveAll

In the second I get:

Duplicate attribute cacheName in annotation @CacheRemoveAll

Answer 1

You can't. Annotations can't be repeated and attributes can't be repeated.

You would need a @CacheRemoveAlls annotation but the framework hasn't planned that.

Your best solution is simply to call removeAll for your two caches at the beginning of methodToBeCalled.

The code would be like this:

public class MyClass {
    @Autowired
    private CacheManager cacheManager; // this is a Spring CacheManager

    public void methodToBeCalled(){
        cacheManager.getCache("cache1").clear();
        cacheManager.getCache("cache2").clear();
    }
}
