Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.

Although there are subclasses in java that implement the interfaces of the parent class, But I think javascript can be different from java, It is possible that the parent class in java is an empty class, Subclasses to implement the interface of the parent class, in javascript, I think the common code is completely written in the parent function. If the business logic needs to be changed in the future, or new business logic is added, we can completely use subclasses to rewrite the parent class, so the code has strong scalability and is easier to maintain. Since I am not a professional java, please understand if there is any mistake in describing the knowledge points in java ~ ~

At the same time, firewall is used to replace the original iptables service in centos7, but don't worry, we just need to install iptables and iptables-services through yum source (iptables are usually installed by default, but iptables-services are not installed by default in centos7).
