写了一个mapper接口
package com.nyist.mapper;
import com.nyist.entity.User;
import tk.mybatis.mapper.common.Mapper;
public interface UserMapper extends Mapper<User> {
}
在Service中注入该接口--启动项目,报错一气呵成??
Unsatisfied dependency expressed through field ‘userMapper‘; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.nyist.mapper.UserMapper‘ available:Unsatisfied dependency expressed through field ‘userMapper‘; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.nyist.mapper.UserMapper‘ available:
查看springboot启动类,
import tk.mybatis.spring.annotation.MapperScan;
@MapperScan("com.nyist.mapper")
