截取自项目中的一个service实现类，记录一下：
base类
package com.bupt.auth.service.base; import javax.annotation.Resource; import com.bupt.auth.dao.OauthClientDao;
import com.bupt.auth.dao.PermissionDao;
import com.bupt.auth.dao.ResourceDao;

@Resource(name="oauthDao")
protected OauthClientDao clientDao; public BaseManagerImpl(){} }
