Fix: make Dubbo actuator PropertySource optional

Contribution Overview

The Engineering Context

This contribution was made to the apache/dubbo-spring-boot-projectopen-source repository. The work involved understanding the existing codebase, identifying the underlying engineering problem, implementing a focused solution, and validating the change against the project's existing behaviour and testing standards.

Engineering Problem

Understanding the Problem

The Dubbo actuator auto-configuration expected the dubbo-endpoints-default.properties resource to always be available. If the resource was absent, application startup could fail while processing the PropertySource.

Solution

Implementation Approach

Updated the PropertySource configuration to enable ignoreResourceNotFound. This allows the Dubbo actuator configuration to continue starting when the optional default properties resource is not present.
