Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'userService';
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'com.boron.service.UserService' available: expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

spring mvc ，ide ：
1.controller
@RestController
@RequestMapping("/user")
2.service
@Service
