SpringBoot3.0.3 appears that the test cannot be used

[livk-cloud]

In SpringBoot3.0.3, it is mandatory to specify the Main class for the test.

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

This error occurred when I upgraded from 3.0.2 to 3.0.3. In 3.0.2, there was no such problem

In the update log, I did not get the place where the test has changed

example

[livk-cloud]

I suspect that the change of org.springframework.core.io.support.PathMatchingResourcePatternResolver makes it impossible to search for class

Thanks for the report. Unfortunately, the sample does not reproduce the problem:

Thank you for your answer. There is no problem when I test on another computer. Maybe it is caused by some other unknown factors.

[wilkinsona]

I think this is another symptom of the suspected regression in Spring Framework that's been identified in #34379. @livk-cloud, if I am right, you can avoid the problem by not having any spaces in your application's path.

Yes, my path contains spaces, when I use _ instead of spaces, my program has no problem, maybe it has something to do with windows
