Spring 2.3.4.RELEASE, Mybatis.Spring.boot 2.1.3 : Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

Question

I am using idea to build artifact based on a Mybatis demo project. It is really a simple demo containing:

main class:

@MapperScan(basePackages = "thusca.testMybatis.mapper")
@SpringBootApplication()
public class SampleMybatisApplication{
    public static void main(String[] args) {
        SpringApplication.run(SampleMybatisApplication.class, args);
    }
}

mapper:

@Mapper
public interface CityMapper {

    @Select("SELECT * FROM CITY WHERE state = #{state}")
    City findByState(@Param("state") String state);

}

model:

public class City implements Serializable {
private static final long serialVersionUID = 1L;

    private Long id;

    private String name;

    private String state;

    ...
}

service:

@Service
public class mysqlService{
    @Autowired
    CityMapper mapper;
}

It runs correctly when I run it using GUI mode. However if I build artifact and run it using command java -jar xxx.jar. It always fails and reports error ava.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required.

I googled it and tried all solutions but no one worked.

here is my pom.xml

ps: for my project, only idea can be used to build artifact(jar), mvn command cannot be used.
