The unit test is as follows, but it should have little to do with the unit test code. There is no problem if the project starts normally, but now I want to do some unit tests on spring-boot, but I don’t know why spring-boot cannot parse viewResolver under unit tests?

Your unit test has nothing to do with MVC, so you can’t write @WebAppConfiguration. Just use the normal @SpringBootTest.
If you want to test MVC, you can read the document Auto-configured Spring MVC tests here
