Spring boot requests exception handling and returns the corresponding HTML page

Through previous studies, I know that the middleware can preprocess HTTP requests and return corresponding pages (for example, if there is a 404 exception, you can return an exception interface written by yourself instead of the default whiteboard 404 page, which is ugly). In fact, spring boot also provides such a function.

404 exception handling:

500 exception handling:

The file path in the above code is based on the file directory structure of the spring boot framework.

In this way, the personalized handling of the two most common exceptions is completed. You may encounter more types of exceptions in the future, and you still need to continue to learn.
