IBatisNet.DataMapper 升级到 1.6.2 之后报错

 private static volatile ISqlMapper _mapper = null;

        protected static void Configure(object obj)
        {
            _mapper = null;
        }

        protected static void InitMapper()
        {
            ConfigureHandler handler = new ConfigureHandler(Configure);
            DomSqlMapBuilder builder = new DomSqlMapBuilder();
            _mapper = builder.ConfigureAndWatch(handler);
        }

        public static ISqlMapper Instance()
        {
            if (_mapper == null)
            {
                lock (typeof(SqlMapper))
                {
                    if (_mapper == null) // double-check
                    {
                        InitMapper();
                    }
                }
            }
            return _mapper;
        }

        public static ISqlMapper Get()
        {
            return Instance();
        }

编译通过了，_mapper = builder.ConfigureAndWatch(handler);老是报 The error occurred while Validate SqlMap config.

查到原因：升级之后所有配置文件采用标准XML格式了！

可参照：http://shanyou.cnblogs.com/archive/2005/10/17/256720.aspx 进行配置！
