Today, I would like to talk to you about the use of model in SpringMVC. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

Model is a concept, not a specific parameter or other concrete embodiment. MVC is a commonly used standard design pattern in software engineering, model (model layer)-view (view layer)-controller (control layer).

Simply put, the model includes your data model (such as pojo or bean) and business model (such as login, registration operation, etc.), while the controller layer represents your model layer in view.

Suppose a simple business is called in the public String aa (Users user) you write to determine whether the incoming user is empty "return user! = null?user.tostring (): new User (). Tostring", generally such logic code

Just write in the business layer, controller return data format to meet your own needs, in line with this specification is a MVC, the benefits of good code, good reusability, loose coupling and so on.

After reading the above, do you have any further understanding of the use of model in SpringMVC? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
