错误原因

没有配置mapper位置。

解决方法

方法一

启动类中指定要扫描的Mapper接口的包路径。

import org.mybatis.spring.annotation.MapperScan;

@SpringBootApplication
@MapperScan({"com.example.mapper1", "com.example.mapper2"})
public class TestApplication {

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

}

方法二

配置文件中指定xml的位置。

mybatis:
  mapper-locations: classpath:mapper/*.xml
