Bugfix

• Description

why is it so important / why do we need this / what problem it solves.
If we are based on plug-ins, there is no way to scale our business based on exceptions
The code is so old that it doesn't know how the response body should return,
For example:

We authenticate the user through the plug-in, if the user does not have permission, theory
The upper system should tell the user that there is no access permission. Normally we can do that in java
Throw an exception and wrap the response by catching the exception

• How to fix?

This pr didn't import any new features, just refactoring, right?

I think this PR provides the ability to extend exceptions through spi, and I think this is also the ability of this plugin to improve

This code logic is not very difficult, maybe I describe the problem, you can look at the implementation of the code, in fact, can solve the business above the exception capture pain points
