Implementation of the method of passing time between Vue and SpringBoot

Preface

In the development of Vue and Spring Boot, it is often necessary to pass time data between the front-end and the back-end. This article will explain how to pass time in Vue and Spring Boot and keep data consistent and correct.

1. The front-end passes time to the back-end:

// Front-end code (Vue)export default {
  methods: {
    sendDataToBackend() {
      const currentDate = new Date();
      const timestamp = (); // Convert time to time stamp      // Send data to the backend      // ...
    }
  }
}

In the above example, we use new Date() to create a Date object representing the current time. The getTime() method can then be used to convert the time to timestamp for processing when passed to the backend.

2. The backend receives time and processes:

In the backend (Spring Boot), the time data passed by the frontend can be received and processed and converted as needed.

Sample code:

// Backend code (Spring Boot)@RestController
@RequestMapping("/api")
public class MyController {
    @PostMapping("/processData")
    public void processData(@RequestParam("timestamp") Long timestamp) {
        Date receivedDate = new Date(timestamp); // Create date object based on timestamp        // Process the received time data        // ...
    }
}

In the above example, we define a method to receive time data in the backend controller processData(), which receives the timestamp parameters passed by the frontend through the @RequestParam annotation. The date object can then be created using the timestamp for further processing and operation.

3. Maintain time zone consistency:

When passing time between the front-end and the back-end, it is important to ensure consistency of time zones. It is generally recommended to use UTC time on both the front end and the back end to pass and store time data to avoid problems caused by time zone differences. The front-end can use the toUTCString() method to convert time to UTC string, and the back-end can convert and process time zones as needed.

Summarize

Through this article, you learned how to pass time data in Vue and Spring Boot. You understand how to use Date objects and timestamps on the front end to represent time and process and convert as needed on the back end.

In actual development, it is very important to ensure time consistency between the front-end and the back-end. It is recommended to use UTC time to pass and store time data, and to convert and process time zones as needed.
