錯誤原因：沒有在主函數(shù)的類中對Mapper層進行掃描。

解決：加上對mapper層的掃描MapperScan

@ComponentScan(basePackages = { "cn.iponkan.controller"})

@MapperScan(basePackages = {"cn.iponkan.mapper"})

@EnableAutoConfiguration

public class SpringBootApplication {

????public static void main(String[] args){

????????SpringApplication.run(SpringBootApplication.class,args);

????}

}
