springboot+mybatis,扫描不到mapper
- 无法扫描到接口实现,'com.sclp.mapper.GenTableMapper' that could not be found.
Description:
Field genTableService in com.sclp.controller.GenController required a bean of type 'com.sclp.mapper.GenTableMapper' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.sclp.mapper.GenTableMapper' in your configuration.
需要在主启动类和mapper接口上分别使用@MapperScan
、@Mapper
,将mapper注入spring容器;
- @MapperScan注解将非mapper接口扫描到容器,Field genTableService in com.sclp.controller.GenController required a single bean, but 2 were found
Description:
Field genTableService in com.sclp.controller.GenController required a single bean, but 2 were found:
- genTableServiceImpl: defined in file [D:\Work_soft\Workplace\sclp\sclp-gen\target\classes\com\sclp\service\impl\GenTableServiceImpl.class]
- IGenTableService: defined in file [D:\Work_soft\Workplace\sclp\sclp-gen\target\classes\com\sclp\service\IGenTableService.class]
Action:
Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
在使用@MapperScan注解时指定扫描范围@MapperScan(basePackages={"com.sclp.mapper"})
