Consider defining a bean of type 'com.bdqn.springboot1.service.impl.UserServiceImpl' in your configuration.

To define a bean of type 'com.bdqn.springboot1.service.impl.UserServiceImpl' in your configuration, you can use the `@Bean` annotation in Spring. Here's an example:

@Configuration
public class AppConfig {

    @Bean
    public UserServiceImpl userService() {
        return new UserServiceImpl();
    }
}

In this example, the `@Configuration` annotation indicates that the class is a configuration class. The `@Bean` annotation on the `userService()` method tells Spring to create a bean of type `UserServiceImpl`. You can then use this bean in other parts of your application by injecting it using `@Autowired`.

Make sure to replace `com.bdqn.springboot1.service.impl.UserServiceImpl` with the correct package and class name for your project.
