UnsatisfiedDependencyException

UnsatisfiedDependencyException is an exception that occurs in software development when a bean or dependency cannot be injected or resolved at runtime.

In the context of Spring Framework, this exception is thrown when a bean requires another bean to be present in the Spring application context but it is not available or cannot be created. This can happen if there is a circular dependency between beans, or if a required dependency is missing or misconfigured.

To resolve this issue, you can check the configuration of your beans and make sure that all required dependencies are present and correctly configured. You can also try to break a circular dependency by using constructor injection or setter injection with the @Autowired annotation. Additionally, you can enable debug logging to get more information about the root cause of the exception.
