封裝處理下Polly重試

private ILogger<PollyHelper> _logger;
        /// <summary>
        /// 
        /// </summary>
        /// <param name="logger"></param>
        public PollyHelper(ILogger<PollyHelper> logger)
        {
            _logger = logger;
        }
        /// <summary>
 

        /// 
        /// </summary>
        /// <param name="exception"></param>
        /// <param name="action"></param>
        public void PollyRetry<T>(Action action) where T : Exception
        {
            var policy = Policy
               .Handle<T>()
               .Retry(
 
2, (ex, count) =>
               {
                   _logger.LogError("執行失敗!重試次數 {0}\r\n異常來自 {1}", count, ex.GetType().Name);
               });

            policy.Execute(action);
        }

調用重試

 _pollyHelper.PollyRetry<UserServicesDomainException>(() =>
            {
                
 
throw new UserServicesDomainException("斯大林附近打開了房間");
            });

執行結果如下

Polly公共處理 -重試（Retry）
