Are you looking to streamline your file upload process in a modern web application? Look no further! MyUploader combines the power of Vue.js with Plupload for the frontend and Spring Boot integrated with MyBatis for the backend, creating a seamless experience for managing file uploads. In this article, we’ll delve into how to get started with MyUploader and illustrate the core functionalities with some engaging analogies!

Setting Up MyUploader

Before you dive into the code, it’s essential to clone the repository to get started:

git clone https://github.com/gaoyuyue/MyUploader

Once you have the project structure in place, you are ready to begin your journey with file uploads!

Understanding the Core Functionality

At the heart of MyUploader is the upload functionality that hinges on a set of well-structured methods. Think of these upload methods like a well-coordinated orchestra. Each musician (method) plays their part perfectly to create a harmonious tune: the upload itself! Let’s look at the methods involved:

• write(String target, InputStream src): This method behaves like a glue that binds two materials together—your target and the input stream, ensuring the uploaded file is set in place.
• upload(String name, String md5, Long size, Integer chunks, Integer chunk, MultipartFile file): Picture this as the conductor signalling different sections to play at precise moments. It manages the upload process, directing how chunks are sent based on conditions.
• writeWithBlok(String target, Long targetSize, InputStream src, Long srcSize, Integer chunks, Integer chunk): This functions like a meticulous sculptor gradually refining the uploaded file into its final form, ensuring accuracy through each chunk of data.

Code Explanation with an Analogy

Let’s take a closer look at the method writeWithBlok and understand it with the help of a bank vault analogy:

public static void writeWithBlok(String target, Long targetSize, InputStream src, Long srcSize, Integer chunks, Integer chunk) throws IOException {
    RandomAccessFile randomAccessFile = new RandomAccessFile(target,"rw");
    randomAccessFile.setLength(targetSize);
    if (chunk == chunks - 1)
        randomAccessFile.seek(targetSize - srcSize);
    else
        randomAccessFile.seek(chunk * srcSize);
    byte[] buf = new byte[1024];
    int len;
    while (-1 != (len = src.read(buf)))
        randomAccessFile.write(buf,0,len);
    randomAccessFile.close();
}

In this analogy, think of the target as a bank vault. The src input stream is like cash being deposited. The targetSize indicates how much cash the vault can hold, while targetSize – srcSize determines exactly where to place the newfound cash. chunks and chunk indicate that money is being deposited in parts rather than all at once, with each portion carefully placed in its designated spot to avoid clutter.

Troubleshooting Tips

While setting up and utilizing MyUploader, you may encounter some common issues. Here are some troubleshooting ideas:

• File Not Uploading: Ensure that your backend server is running and accessible. Sometimes the simplest thing—a server failure—can halt your progress. Double-check your API routes and network settings.
• Chunk Uploading Issues: If chunks are not being uploaded correctly, check the parameters you’re sending from the frontend, such as name, md5, and chunks. Make sure each chunk has a valid identifier.
• Permissions Errors: If you encounter permission errors, verify that your application’s user has the necessary access rights to write to the specified directory.
