I checked through the Internet and found that many people encountered such problems, but they did not solve my problems. Finally, I found that this class was not found in the imported package, I checked carefully and found that a package was missing, I used spring3.2 version, less spring-web-3.2.0.jar this package, import this package, the problem is resolved immediately !, Hope to solve other people's problems!
