Hey, it took me two days to waste my time. I used the db database by default before, and I didn't find any problems. Later, I needed to use a different database instance, and then I found the problem of the gods when spring integrates mongo!
一直在上报Command failed with error 13：‘not authorized on db to execute command ’

Hey, let's not talk about it, let's take a screenshot to show the solution
