在进行MyBatis与spring问题
yy

在进行MyBatis与spring整合时不管是使用映射器方法还是纯的XML方法都出现下列问题,查找资料和官方文档都感觉代码与逻辑没有错!!求解答!
下面是是使用映射器方法的spring配置文件beans.xml的内容:















其中UserMapper的代码是:
package xx.xx;
import java.util.List;
import org.apache.ibatis.annotations.Select;
import com.yiwei.po.User;
public interface UserMapper {
@Select("select * from user")
public List findAllUser();

@Select("select * from user where id=#{id}")
public User findUserById(int id);

}

UserDAOImpl中的代码是:
public class UserDAOImpl implements UserDAO {
private UserMapper userMapper;
public UserMapper getUserMapper() {
return userMapper;
}

public void setUserMapper(UserMapper userMapper) {
    this.userMapper = userMapper;
}
    @Override
public List<User> findAllUsers() {
    // TODO Auto-generated method stub
    List<User> users = userMapper.findAllUser();
    return users;
}

}

下面是测试出现的错误:
