}

com.xxx.dao.userManagement.AdminDao

package com.xxx.dao.userManagement;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.xxx.mapper.userManagement.AdminMapper;

    }
    
    public Admin login(String username, String password) {
        return adminDao.login(username, password);
    }
}

代码很简单,与之前的基本一样,只是名字换了而已。

值得注意的是包名:com.xxx.mapper.userManagement而非com.xxx.userManagement.mapper。
