Case 1: Just use the ueditor tool
Solution: When using ueditor for the first time, the front and back ends of the project are separated, and there are relevant configuration files in the front and back ends. Check the background debug test and show that no files are found.
Then look for the problem. Some people say that there is a conflict between the upload of SpringMVC and the ueditor. You only need to comment out the configuration.
Case 2: ueditor and springMVC upload pictures do not conflict
Solution: Override the isMultipart method in the CommonsMultipartResolver class
