Evict all element in EhCache

I am using EhCache with spring and need to expose an endpoint that will evict all element in given EhCache. But I am not able to find any method that evict all element. It is trivial and might be discussed already but I could not find any resource on internet. Please provide pointers.

Solution

  • are you using Spring Cache ? then set true to allEntries property 

    @Cacheable("myCache")
public String getCache() {
    try {
        Thread.sleep(3000);
    } catch (final InterruptedException e) {
    }
    return "aaa";
}

@CacheEvict(cacheNames = "myCache", allEntries = true)
public void evictAll() {
}

    or if you want to delete all caches that you defined 

    @Autowired
CacheManager cacheManager;

public void evictAll() {
    cacheManager.getCacheNames()
            .stream()
            .forEach(n -> cacheManager.getCache(n).clear());
}
