My brother is learning SSH racks recently! When I saw others writing, I found that when calling MODEL, some use IOC or some use NEW to instantiate objects! Please also explain the advantages, disadvantages and trade-offs of these two methods in actual projects!
new manages dependencies by the object itself,
IoC is managed by the container, which means that the container actively injects objects.
Which one you choose depends on your application.
I think it depends on whether your program is interface-oriented programming. If you provide high scalability and flexibility for you, you should use reverse injection, because the parameters of a function are one interface or another interface. transfer.
