2-4 - Merger interface failed to load
- Dubbo provides an SPI extension Merger interface that aggregates the responses of all downstream providers. When Dubbo loads the user-defined extension Merger interface, the loading configuration fails.
Troubleshooting and resolution steps
- Refer to the community SPI extension manual to check the implementation of the user-defined extension Merger interface, [“SPI Extension User Manual”](https://dubbo.apache.org/zh/docs3-v2/java-sdk/reference-manual /spi/).
