org.springframework.beans.factory.UnsatisfiedDependencyException is a runtime exception thrown by the Spring Framework when it encounters a bean that cannot be instantiated or wired up due to a missing or unsatisfied dependency. This can happen when a bean requires another bean as a dependency, but that bean has not been defined or is not available in the application context. The exception message will typically provide details about the missing dependency and the bean that requires it. To resolve this exception, you will need to ensure that all required dependencies are properly defined and configured in the application context.
