Before the environment changes, the code that installs the Person in the database can run normally. For example, loading a Person from a database may apply to applications of the first version, but for the second version, you may need to add the function of loading a Person from the Web service. In fact, this class has become "stone", because it is directly using the implementation class and the changes that can be made now are very limited
