Consider defining a bean of type '*Mapper' in your configuration.

pom.xml

<dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.0.1</version> </dependency>

1.在Mapper接口上贴@Mapper

@Repository @Mapper public interface CommodityMapper { /** * 查询所有商品信 * @return List<Commodity> 所有商品信 */ List<Commodity> selectAll(); }

2.启动类上贴@MapperScan(value = "com.xiami.springboot.sbootdemo.mapper")注解,告诉Spring,Mapper接口的位置

@SpringBootApplication @MapperScan(value = "com.xiami.springboot.sbootdemo.mapper") public class SbootdemoApplication { public static void main(String[] args) { SpringApplication.run(SbootdemoApplication.class, args); } }
