How do the vue framework and the springboot framework interact with the front and back ends?

Vue and Spring Boot interact with the front-end and back-end through the RESTful API, and the data is passed in JSON form: Vue issues an HTTP request to the Spring Boot API endpoint. Spring Boot processes the request and generates response data. The response data is returned to Vue to update the front-end interface. For example, Vue uses axios to make a GET request to obtain data, while Spring Boot's controller methods handle the request and return the data.

Front-end and back-end interaction between Vue framework and Spring Boot framework

Vue framework is a framework for building front-end user interfaces JavaScript framework, and the Spring Boot framework is a Java framework for building backends. These two frameworks can be seamlessly integrated to achieve front-end and back-end interaction.

Interaction method

The main way of interaction between Vue and Spring Boot is through the RESTful API. RESTful API is an architectural style for interaction through HTTP requests and responses.

The Vue framework uses JavaScript libraries such as axios or fetch to make HTTP requests, while the Spring Boot framework uses the @RestController annotation to create RESTful API endpoints to handle these requests.

Data passing

In HTTP requests, the Vue framework can pass data to the Spring Boot backend as a request body in JSON form. The backend receives the request and processes the data, then returns the response data to the Vue framework as a response body in JSON form.

Interaction process

The typical interaction process between Vue and Spring Boot is as follows:

1. The Vue framework issues an HTTP request through axios or fetch. Backend API.
2. The Spring Boot backend receives the request and calls the corresponding controller method according to the requested path and method.
3. The controller method processes the request and generates response data.
4. The response data is returned to the Vue framework and the front-end interface is updated.

Example

The following is a simple example that demonstrates the interaction between Vue and Spring Boot:

Vue Framework Code:

<code class="javascript">import axios from 'axios';

export default {
  methods: {
    async getData() {
      const response = await axios.get('http://localhost:8080/api/data');
      this.data = response.data;
    },
  },
};</code>

Spring Boot backend code:

<code class="java">import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class DataController {

  @GetMapping("/api/data")
  public List<Data> getData() {
    return List.of(new Data(1, "Data 1"), new Data(2, "Data 2"));
  }
}</code>

In this example, the Vue framework uses axios to issue a GET request to the Spring Boot backend to obtain data. The backend processes the request and returns data, and the Vue framework receives the data and updates the front-end interface.
