UnsatisfiedDependencyException

UnsatisfiedDependencyException is a type of exception that occurs when a dependency injection framework is unable to resolve a dependency. This can happen when a required bean or component is missing, or when there is a misconfiguration in the dependency injection configuration.

For example, in Spring framework, if a bean is defined with a dependency on another bean that is not present in the application context, then an UnsatisfiedDependencyException will be thrown at runtime.

To resolve this exception, you need to ensure that all the required dependencies are properly configured and present in the application context. This can involve checking the configuration files, ensuring that all the required dependencies are included in the project, and verifying that the dependency injection framework is properly configured.
