org.springframework.beans.factory.NoSuchBeanDefinitionException

The org.springframework.beans.factory.NoSuchBeanDefinitionException is an exception that is thrown when a bean that is being requested from the Spring container does not exist.

This exception is thrown when the Spring container cannot find a bean with the specified name or type. It may occur due to a typo in the bean name, incorrect configuration of the Spring container, or if the bean has not been defined in the configuration file.

To resolve this exception, you should check the bean name and make sure it is spelled correctly. Additionally, ensure that the bean is defined in the configuration file and it has the correct configuration. If everything is correct and you still encounter the exception, then it may be necessary to review your Spring configuration file and the dependencies of the bean to ensure that they are correctly defined.
