I reported this error during the list interface test. After searching online, I found that the reason for this error is that the project POM relies on PageHelper and mybatis plus at the same time, resulting in the jar conflict of jsqlparser.

The code uses a method in one version, but the request uses another version, which does not have the method in the other version. Therefore, you can delete the jsqlparser dependency under PageHelper in the POM file

Normal requests can be made after deletion.
