Background

The Logger abstraction layer relied on by Dubbo provides logging capabilities, but most exception logs do not include troubleshooting explanations, making it difficult for users to handle issues when they see exceptions.

To address this problem, starting from version 3.1 of Dubbo, an error code mechanism has been introduced. It links the error code FAQ in the official documentation with the logging framework. When exceptions are output in the log abstraction, the corresponding official documentation link is also provided to guide users in self-troubleshooting.
