This error message typically indicates that the bean in question (in this case, GlobalMethodSecurityConfiguration) is not being loaded by Spring Boot as expected.

There are a few possible reasons for this:

The bean is not in the package scanned by Spring Boot. If you are using the @SpringBootApplication annotation, it scans for beans in the same package as the annotated class, as well as its subpackages. So, the bean class should be located in a package that is within the same package hierarchy.
The bean is not annotated with @Configuration, which is required for it to be considered a configuration class by Spring Boot.
The bean class is not being instantiated because another configuration class is taking precedence.
