Solution: Error: (5, 33) java: cannot find the symbol
IDEA reported this error when it started running, prompting: "Error:(5, 33) java": Cannot find the symbol .
Problem: This error is still reported when there is no problem in the inspection. Later, the inspection found that it was packaged with maven before. Therefore, no matter how you modify it later, the effect is the same.
Solution: Use maven's "clean" function to clear the original jar package, and then re-run
