This error often occurs when starting a Spring project
as shown in the picture
Because a lot of configuration files need to be loaded when the project starts, and the dubbo configuration files need to be loaded when the dubbo project starts
This is when I was looking for the attribute dubbo.application.name. I didn’t find it. To put it bluntly, I didn’t find the loaded configuration file.
Checked and found that the Maven configuration is not checked, and it can be started normally if it is checked.
