How can data be exchanged between Uniapp and Spring Boot?

To achieve data exchange between Uniapp and Spring Boot, you can follow these steps:

1. In a Spring Boot project, create a Controller class to handle requests and return data. This class can be annotated with either @RestController or @Controller.
2. In the Controller class, create the corresponding request handling method and annotate it with @RequestMapping or other relevant annotations. Within the method, you can call the appropriate Service or Dao layer methods to retrieve data.
3. In the Uniapp project, you can use uni.request or other related methods to send requests to the Spring Boot backend API. Both GET and POST request methods are supported.
4. In Uniapp projects, you can handle the data returned from the backend by using the “then” method to process the data, such as rendering the page or updating the data.

It is important to note that Uniapp is a front-end framework based on Vue, while Spring Boot is a framework used for building back-end applications. In Uniapp, you can use Vue syntax and framework features to handle front-end interactions and displays, while Spring Boot is responsible for handling back-end logic and data operations. Through these steps, data interaction between Uniapp and Spring Boot can be achieved.
