In the process of software development, design patterns provide us with efficient solutions to various complex programming problems. As a structural design pattern, the Proxy Pattern is widely used in many practical development scenarios. This article will deeply analyze the concept of the Proxy Pattern, the difference from other similar patterns, the problems it solves, examples in practical applications, precautions, and implementation examples in Golang. What is the Proxy Pattern? The Proxy Pattern is a design pattern that allows an object to…

Introduction In modern software development, design patterns provide us with reusable solutions to common problems in a specific context. As a structural design pattern, the adapter pattern is particularly widely used in Golang. This article will introduce the concept of the adapter pattern, the difference from other similar patterns, the problems it solves, application examples in actual development, precautions, and implementation examples in Golang. What is the adapter pattern? The adapter pattern…

1. Introduction Design patterns play a vital role in software development. They provide proven solutions to common design problems and improve the readability and maintainability of code. Design patterns help developers quickly find appropriate solutions when encountering complex problems, thus saving time and reducing errors. Facade Pattern is a structural design pattern whose main purpose is to provide a simple interface for complex subsystems, making it easier for users to interact with…

Introduction Design patterns play a vital role in software development, helping developers solve specific problems and improving the maintainability and scalability of code. Singleton pattern and prototype pattern are two common creational design patterns, which are used to control the creation and replication of objects respectively. This article will explore the definitions of these two patterns, the problems they solve, implementation examples, as well as their differences and application scenarios. Overview of Singleton Pattern Definition Singleton Pattern is a creational design pattern…

Introduction In software development, design patterns are an effective way to solve common problems. The Builder Pattern is one of the commonly used creational design patterns, which aims to simplify the construction process of complex objects. This article will explore the implementation of the Builder Pattern in Golang, compare the differences with other creational patterns, and discuss its applicable scenarios. Overview of the Builder Pattern The Builder Pattern builds a complex object by using a builder object. This pattern can separate the construction process of an object from its representation...

What is the Abstract Factory Pattern? The Abstract Factory Pattern is a creational design pattern that provides an interface for creating a series of related or interdependent objects without specifying their concrete classes. The Abstract Factory Pattern provides a consistent interface for clients to create different types of products. The structure of the Abstract Factory Pattern The Abstract Factory Pattern usually includes the following components: Abstract Factory Interface: defines the interface for creating products. Specific…

What is the Factory Method Pattern? The Factory Method Pattern is a creational design pattern that creates objects by defining an interface, but defers the specific implementation of the object to the subclass. This means that the Factory Method Pattern allows subclasses to decide which class to instantiate, making code expansion more flexible and easier to maintain. Compared with the Simple Factory Pattern, the Factory Method Pattern no longer relies on a single factory class, but implements object creation through an abstract factory interface. This…

What is the Simple Factory Pattern? The Simple Factory Pattern is a creational design pattern that uses a factory class to instantiate different types of objects. Based on the parameters passed in, the factory class decides which specific class to create. The Simple Factory Pattern is often used to reduce the client code's dependence on specific classes, ensuring that the code is easier to maintain and extend. In the Simple Factory Pattern, the factory class is responsible for the object creation logic, and the client does not need to worry about how to create the object, but only needs to...

Design Patterns is a summary of experience in software engineering, which provides solutions to common software design problems. Although design patterns themselves are not specific codes, they are some reusable design ideas and principles that can help developers write more flexible, maintainable and scalable codes. This blog will introduce the definition, meaning, classification and common examples of each type of design pattern in detail. By understanding these contents in depth, readers can understand how to use them in projects...

From stand-alone to cluster: Deploy MySQL with Docker Compose Introduction In modern applications, database systems play a vital role, especially MySQL. MySQL is a widely used open source relational database management system, which is popular for its high performance, reliability and flexible scalability. With the rise of microservice architecture, how to effectively deploy and manage MySQL database has become a major challenge for developers. With the help of Docker…
