Final answer:
To fix the 'No qualifying bean of the type found for dependency' error in Spring, verify the configuration and ensure that the bean is properly defined. Check if the bean is annotated correctly and if the package containing the bean is being scanned by Spring.
Step-by-step explanation:
The error message 'No qualifying bean of the type found for dependency' occurs when the Spring framework is unable to find a bean that matches the requested dependency. This issue can be fixed by verifying the configuration and ensuring that the bean is properly defined.
One possible reason for this error is that the bean may be missing or not configured correctly in the Spring context. Make sure that the bean is annotated with the correct annotations, such as 'Component', 'Repository', or 'Service', depending on its role.
Additionally, check if the package containing the bean is being scanned by Spring. You can do this by adding the 'ComponentScan' annotation to your configuration class, specifying the package to scan.
