Consider defining a bean of type `xxx` in your configuration问题解决问题解决

在使用SpringBoot装配mybatis时出现了异常

***************************
APPLICATION FAILED TO START
***************************

Description:

Field studentService in com.example.demo.action.StudentController required a bean of type ‘com.example.demo.service.StudentService‘ that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type ‘com.example.demo.service.StudentService‘ in your configuration.

Process finished with exit code 0

查了一下，大意是因为我的StudentService没有被SpringBoot的自动装配扫描到，解决办法就是在SpringBootApplication类上加一行注解指定需要被装配的Service包

Like this：

@ComponentScan(basePackages = {"com.example.demo.service"})
public class SpringBootApplication {
