Consider defining a bean of type 'person.post.mapper.UserMapper' in your configuration.

To define a bean of type 'person.post.mapper.UserMapper' in your configuration, you can use the `@Bean` annotation in a configuration class or XML configuration file. Here's an example using Java configuration:

@Configuration
public class MyConfig {
    
    @Bean
    public UserMapper userMapper() {
        return new UserMapper();
    }
}

In this example, the `userMapper()` method is annotated with `@Bean`, indicating that it should be registered as a bean in the Spring container. The method returns an instance of the `UserMapper` class, which will be managed by Spring.

Make sure to replace `UserMapper` with the actual class name and adjust the configuration according to your specific requirements.
