According to the messages, it seems the required class is not in the right path. I found the package path is wrong, the full package path of GlobalAuthenticationConfigurerAdapter is org.springframework.security.config.annotation.authentication.configuration not the given one above ,
please tell me how to solve this problem?

The class changed packages in Spring Security 5. I would guess that you either have a mixture of Spring Security versions on the classpath, or you are trying to use some code that requires Spring Security 4 with Spring Security 5. Neither of these should be caused by Spring Boot so I am going to close this issue. If you require further help, please ask on Stack Overflow or Gitter. As mentioned in the guidelines for contributing, we prefer to use GitHub issues only for bugs and enhancements.

I'm having the same issue. Did someone figure out what is causing this?
I know it's not a Spring Boot related issue, but if you have some idea, please give us some hints ;)

[catacraciun]

FYI: I'm doing a little 'hack' until a proper solution will be out. I just created the missing class extending the new one:

public class GlobalAuthenticationConfigurerAdapter extends org.springframework.security.config.annotation.authentication.configuration.GlobalAuthenticationConfigurerAdapter {

}

Hope to remove this asap :)

[wilkinsona]

@catacraciun You should be able to remove it now if you update your code or your dependencies so that they're compatible with Spring Security 5.

I have the same issue with a new project using only spring security 5 @wilkinsona

EDIT: found out that spring-security-oauth2 is not at the same version that spring boot, my bad. Works now.
