spring-boot bug project summary

1, when the project started, can not find mapper file

Description:

Field stuMapper in com.zb.service.impl.StuServiceImpl required a bean of type 'com.zb.mapper.StuMapper' 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.zb.mapper.StuMapper' in your configuration.

The reason is: mapper is not injected into the vessel

The solution is: In the startup file, add @MapperScan (basePackages = "com.zb.mapper"), basePackages is the folder where the file mapper

@SpringBootApplication
@MapperScan(basePackages = "com.zb.mapper")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
