Hi,
I have a Memcache wrapper class with a set of public static methods for
getting and setting application-specific key:value pairs. They use a set of
private static methods defined here:
private static boolean has(String key) {
return MemcacheServiceFactory.getMemcacheService().contains(key) &&
get(key).length()>0;
}
private static String get(String key) {
try {
return (String)
MemcacheServiceFactory.getMemcacheService().get(key);
} catch (Exception e) { return ""; }
}
private static void put(String key, String value, int expiry) {
MemcacheServiceFactory.getMemcacheService().put(key, value,
Expiration.byDeltaSeconds(expiry));
}
private static void delete(String key) {
MemcacheServiceFactory.getMemcacheService().delete(key);
}
The problem is there is almost no hit rate on my cache. What's wrong with
the code here?
