解决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); } }
