注意：
“AutoMapperConfiguration.Mapper.Map(customerModel, _customer)”方法中必须包含“_customer”参数实例，否则在赋值映射时会导致
_customer.CreatedDateTime属性实例为：0001-01-01 00:00:00.0000000
_customer.Avatar属性实例为：空字符串。
1、如果不包含“_customer”参数实例其赋值映射过程的实质为：new Customer()=customerModel; _customer=new Customer();所以才会导致上述状况的产生。
2、如果包含“_customer”参数实例其赋值映射过程的实质为： _customer=customerModel;从而避免了上述状况的产生。
