            return Task.FromResult(new List<string>());
        }
        [Cacheable("getNames_Param", Key = "#param.Id", Condition = "#param.Id>=0&&#param.Name!=null", ExpirationPolicy = ExpirationPolicy.Absolute, ExpirationUnit = ExpirationUnit.Minute, ExpirationValue = 1)]
        public virtual Task<List<string>> GetNames(TestServiceParam param)
        {
            return Task.FromResult(new List<string>() { param.Id.ToString(), param.Name });
        }
        [Cacheable("getTest", Condition = "#id>0", ExpirationPolicy = ExpirationPolicy.Absolute, ExpirationUnit = ExpirationUnit.Minute, ExpirationValue = 1)]
        [CachePut("getTest_CachePut", ExpirationPolicy = ExpirationPolicy.Absolute, ExpirationUnit = ExpirationUnit.Minute, ExpirationValue = 1)]
        protected virtual Task<List<string>> Get(int id)
        {
            // support protected method
            return Task.FromResult(new List<string>());
        }

        {
            return Task.CompletedTask;
        }     
        [CacheEvict("getTest", Condition = "#id>0")]

       .....................
       //at last
       services.AddSpringCaching();
