The reason why the logic for creating an object is put into a separate class is that it can be used by multiple clients. And separates the creation and use of objects. However, this design also has many defects. First of all, SimpleFactory is a specific class, so we must program for the implementation, making the system lose its flexibility in this respect. Second, if we add new products, we have to modify the code in SimpleFactory, which violates the opening and closing principle. The above model is also called simple factory. He does not appear in GOF mode, it is more like a programming habit.
The maintenance of exceptions is much simpler. It is mainly to handle faults. It should be noted here that all faults should be handled with documents to check, that is to say, the application, approval, processing and other processes should be completed. If it is urgent, it should be supplemented later, which is helpful for internal audit of related events.
