AutoCAD快速开发框架之日志Logging

日志模块的结构图如下：

日志模块通过继承Load函数，实现日志工厂Log4netLoggerFactory的注册和Logger的注入，最终只有在调用的类里实现

public ILogger Logger { get; set; }

就能输出日志。

        private readonly ICommonServices _services;
        private readonly IBlockService _blockService;

        public ModelSpaceService(
            ICommonServices services,
            IBlockService blockService)
        {
            _services = services;
            _blockService = blockService;
            Logger = NullLogger.Instance;
        }

        public ILogger Logger { get; set; }

        public virtual void InsertBlockReference(string name, Point3d position)
        {
            Block block = _blockService.GetBlock(name);
            if (block == null)
            {
                Logger.Debug(string.Format("块'{0}'不存在! ", name));
                return;
            }
        }
    }
}
