Consider defining a bean of type `xxx` in your configuration問題解決

在使用SpringBoot裝配mybatis時出現了異常

***************************
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，大意是由於個人StudentService沒有被SpringBoot的自動裝配掃描到，解決辦法就是在SpringBootApplication類上加一行註解指定須要被裝配的Service包

Like this：

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