Design pattern (ix) Appearance mode facade (structural type)1. Overview
Appearance mode, we use the appearance of packaging, so that the application can only see the appearance of objects, but not to see the details of the object, this will undoubtedly reduce the complexity of the application, and improve the maintainability of the program.Example 1: A power master switch can control four lights, a fan, an air conditioner and a TV set to star
The definition of appearance mode (facade): Provides a consistent interface for a set of interfaces in a subsystem.Facade A typical application is the database JDBC application, the following example of the operation of the database: public class Dbcompare {Connection conn = null;PreparedStatement prep = NULL;ResultSet rset = null;try {Class.forName ("conn = Drivermanager.getconnection (" String sql = "SELECT * from PREP = conn.preparestatement (
The two new classes of containers (Container) and facades (facade) are introduced in tp5.1The official documentation has been defined:
The container (Container) implements the unified management of the class, ensuring the uniqueness of the object instance.
The façade (facade) provides a static calling interface for classes in the container (Container), which brings better testability and extens

1. Introduction
The facade provides a "static" interface for the binding class in the service container of the application. Laravel has many built-in facades that you may be using without knowing. The facade of Laravel serves as the "static proxy" of the underlying class in the service container. compared

The façade (facade) model and the Mediator (mediator) model have a common purpose. They are all communications that provision a set of mutually-coupled objects. However, the façade mode is concerned with how this group of complex objects communicates with the outside world, while the mediator pattern is the provision of communication between this complex set of objects.

experience reach a certain level, and it also means to summarize a lot of good design experience, however, it may not be the case that "no teacher can do anything", or you can say that, on the basis of level and experience, it is time for the system to learn the "mode, it is helpful to learn the experts' summary and verify your own shortcomings.

1. Scenario Simulation
For example, I want to buy a computer.
The first method is to buy accessories and assemble them by yourself. This method requires you to be familiar with accessories.
The second method is to find a professional installation company, put forward their own requirements, and then wait for the computer to be ready.
Obviously, although the second method is costly, customers do not need to know that much.
In this scenario, we can abstract the second method as an example, that is
