xml配置的resultmap找不到指定的类

报错如下：
org.apache.ibatis.exceptions.PersistenceException:

Error building SqlSession.

The error may exist in com/itheima/dao/store/CompanyDao.xml

The error occurred while processing mapper_resultMap[BaseResultMap]

Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML.

Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'com.itheima.domain.Company'. Cause: java.lang.ClassNotFoundException: Cannot find class: com.itheima.domain.Company

xml配置文件如下：

映射类
import com.itheima.domain.store.Company;

import java.util.List;

public interface CompanyDao {

void  delete (Company company);

void  update (Company company);

Company  findById (String id);

List<Company> findAll();

}

自己创建测试方法 为什么xml文件找不到我的实体类呢

这个实体类包名和你填的不一样，少了一个store
