Creating a photo wall for a magic cube is a relatively complex task that involves front-end presentation and back-end data processing. Here, I'll provide a simplified Java backend example that generates a simulated "photo wall" data model and gives a basic frontend HTML page to display the data. Please note that since this is a simplified example, it will not include full user interaction and dynamic data loading, but rather provide a static "photo wall" display.
1. Example 1: Static "photo wall" display
1.1 Backend Java Code (Simulated Data Generation)
import ;
import ;
public class MagicPhotoWall {
static class Photo {
String url;
String title;
Photo(String url, String title) {
= url;
= title;
}
}
public static List<Photo> generatePhotoWall() {
List<Photo> photos = new ArrayList<>();
(new Photo("/", "Photo 1"));
(new Photo("/", "Photo 2"));
// ... Add more photos
return photos;
}
public static void main(String[] args) {
List<Photo> photos = generatePhotoWall();
for (Photo photo : photos) {
("URL: " + + ", Title: " + );
}
}
}
This Java class defines aPhotointernal class to store the URL and caption of the photo, and provides ageneratePhotoWallmethod to generate simulated photo wall data. In themainmethod, we simply print out the data.
1.2 Front-end HTML code (Photo Wall Display)
Next is a simple HTML page for displaying a photo wall. This page will use the mock data generated in the Java code above. In practice, we may dynamically load this data by interacting with the backend via Ajax or other means.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Tanabata Rubik's Cube Photo Wall</title>
<style>
.photo-wall {
display: flex;
flex-wrap: wrap;
gap: 10px;
}
.photo {
width: 150px;
height: 150px;
background-size: cover;
background-position: center;
position: relative;
display: flex;
align-items: center;
justify-content: center;
color: white;
font-weight: bold;
text-shadow: 2px 2px 4px rgba(0, 0, 0, 0.5);
}
</style>
</head>
<body>
<div class="photo-wall">
<!-- The simulated data provided by the backend is used here -->
<div class="photo" style="background-image: url('/');">Photo 1</div>
<div class="photo" style="background-image: url('/');">Photo 2</div>
<!-- ... Add more photo elements -->
</div>
</body>
</html>
This HTML page defines a simple photo wall layout that uses CSS Flexbox to arrange photos. Each photo is adivelement with its background image set to the corresponding photo URL.In practice, we can use JavaScript to dynamically generate thesedivelement and loads the photo data from the backend.
1.3 Notes and extensions
（1）data interaction: In practice, we may need to interact with the backend using Ajax, Fetch API or other technologies to dynamically load photo data.
（2）error handling: Ensure that error conditions are properly handled when loading and processing photo data.
（3）user experience: Consider adding features such as loading animations, paging, sorting and search to enhance the user experience.
（4）safety: If users are allowed to upload photos, be sure to implement appropriate security measures to prevent malicious file uploads.
（5）responsive design: Adjust CSS for different devices and screen sizes to ensure that the photo wall displays well on a variety of devices.
2. Example 2: Building a front-end page for dynamic presentation
Below is a more detailed example that includes a backend service (using the Spring Boot framework) and a frontend page. This example will demonstrate how to create a simple REST API to provide photo data and build a front-end page to dynamically display that data.
2.1 Back-end Java code (using Spring Boot)
First, we create a Spring Boot project and define aPhotoControllerto provide a REST API.
(model class)
public class Photo {
private String id;
private String url;
private String title;
// constructor、gettercap (a poem)setterMethods omitted
}
(Controller class)
import ;
import ;
import ;
import ;
@RestController
public class PhotoController {
@GetMapping("/api/photos")
public List<Photo> getPhotos() {
return (
new Photo("1", "/", "Happy Tanabata!"),
new Photo("2", "/", "Romantic Moments"),
// Add more photo objects
);
}
}
(Spring Boot configuration file, optional)
Properties copy code
=8080
Ensure that our Spring Boot project contains the necessary dependencies such asspring-boot-starter-web。
2.2 Front-end HTML and JavaScript code
Next up is the front-end code, where we'll use native JavaScript to fetch data from the back-end API and dynamically build the photo wall.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Tanabata Rubik's Cube Photo Wall</title>
<style>
/* The style code is the same as the previous example，hereinafter referred to as */
</style>
</head>
<body>
<div class="photo-wall" id="photo-wall"></div>
<script>
fetch('/api/photos') // invoke the backendAPIGet photo data
.then(response => ()) // analyzeJSONdigital
.then(photos => {
const photoWall = ('photo-wall');
(photo => {
const photoElement = ('div');
= 'photo';
= `url(${})`;
= ;
(photoElement);
});
})
.catch(error => ('Error fetching photos:', error));
</script>
</body>
</html>
In this example, we use thefetchfunction from/api/photosendpoint fetches the photo data and parses it into JSON.After that, we iterate through the array of photos and create adivelement, set its background image and title, and finally add these elements to the photo wall container.
2.3 Operation and testing
(1) Start our Spring Boot application.
(1) Open your browser and visithttp://localhost:8080(or the server port we configured).
(3) We should see the photo wall dynamically loaded from the backend API.
This example provides a basic framework that we can extend and optimize according to our needs. For example, we can add more complex layouts, interactive features or styles to enhance the user experience.
