springmvc流程通俗理解
1. SpringMVC是一个基于Java的Web框架，它以模块化的方式提供了Web开发所需的基本功能。
SpringMVC is a Java-based web framework that provides the basic functionality required for web development in a modularized way.
2.它提供了基于MVC模式的体系结构，通过将模型、视图和控制器分离，使得开发和维护变得更加容易。
It provides an architecture based on the MVC pattern, which separates the model, view, and controller, making development and maintenance easier.
3.在SpringMVC中，控制器负责处理请求，并决定如何响应，它使用注解或配置来映射URL到相应的方法上。
In SpringMVC, the controller is responsible for handling requests and deciding how to respond, it uses annotations or configuration to map URLs to corresponding methods.
4.视图负责呈现数据给用户，并与用户进行交互，通常是通过JSP、Thymeleaf等模板引擎来实现。
The view is responsible for presenting data to the user and interacting with the user, usually implemented through template engines such as JSP, Thymeleaf, etc.
5.模型用于封装业务逻辑和数据，它与数据库交互并存储应用程序的状态。
The model is used to encapsulate business logic and data, it interacts with the database and stores the state of the application.
6. SpringMVC还提供了很多特性，如数据绑定、数据验证、国际化等，以满足不同的业务需求。
SpringMVC also provides many features such as data binding, data validation, internationalization, etc., to meet different business requirements.
7.请求处理流程通常是这样的：首先，用户发起一个请求，请求到达DispatcherServlet，然后DispatcherServlet根据配置到对应的Controller进行处理。
The request processing flow is usually like this: first, the user initiates a request, the request reaches the DispatcherServlet, and then the DispatcherServlet finds the corresponding Controller for processing based on the configuration.
8. Controller处理完请求后，返回ModelAndView对象给DispatcherServlet，其中包含了处理结果和视图信息。
After the Controller processes the request, it returns a ModelAndView object to the DispatcherServlet, which contains the processing result and view information.
9. DispatcherServlet接收到ModelAndView对象后，根据视图信息到对应的View进行渲染，最终返回给用户。
After receiving the ModelAndView object, the DispatcherServlet finds the corresponding View based on the view information for rendering, and ultimately returns it to the user.
10. SpringMVC的优势在于结构清晰、灵活性高、易于测试和扩展，因此受到广泛的认可和应用。
The advantages of SpringMVC lies in its clear structure, high flexibility, ease of testing and extension, and thus receive widespread recognition and application.
11.通过使用注解和约定大于配置的方式，SpringMVC可以简化开发流程，提高开发效率。
By using annotations and convention over configuration, SpringMVC can simplify the development process and improve development efficiency.
12. SpringMVC还支持RESTful风格的开发，使得构建RESTful API变得更加简单和便捷。
SpringMVC also supports development in the RESTful style, making it easier and more convenient to build RESTful APIs.
