Springmvc concepts and simple cases
springmvc concept The JavaEE architecture includes four layers, from top to bottom are the application layer, Web layer, business layer, and persistence layer. Struts and SpringMVC are the frameworks of the Web layer, Spring is the framework of the business layer, and Hibernate and MyBatis are the frameworks of the persistence layer. SpringMVC is a […]
RESTful specific case – based on RESTful page data interaction
Based on RESTful page data interaction Needs Analysis (Note: The focus of this case is how to use RESTful in SpringMVC to achieve front-end and back-end interaction, so this case does not interact with the database, and all data uses fake data to complete the development.) Requirement 1: The “Add” picture is as follows, and […]

Polymorphism in C++, its implementation, and two special cases of polymorphism.
1. What is polymorphism? In layman’s terms, it is a variety of forms. The specific point is that when different objects accomplish certain things, they will produce different states. For example: just like: when buying tickets, ordinary people, students, soldiers, etc., they have different results when buying tickets, ordinary people enjoy full-price tickets, students enjoy […]
