This error message usually occurs when Spring is unable to find any beans of the 'UserService' type in your application context.
To resolve this issue, you can try one or more of the following solutions:
1. Check if you have defined a bean of type 'UserService' in your application context. If not, you can add it by using the @Bean annotation or XML configuration.
2. Make sure that the package containing the 'UserService' implementation is included in the component scan configuration. This can be done by adding the @ComponentScan annotation on the main application class, specifying the base package(s) that contain your service implementation.
3. Ensure that the 'UserService' interface is implemented in your project and that it is annotated with @Service.
4. Verify that there are no typos or spelling errors in the package or class names of the 'UserService' implementation.
5. If you are using a dependency injection framework like Spring, make sure that the 'UserService' implementation class is properly annotated with either @Component, @Service, or @Repository annotations.
By following the above steps, you should be able to resolve the "Could not autowire. No beans of 'UserService' type found." error and successfully autowire your 'UserService' component.
