逻辑层：好吧我现在也理解的不深，感觉就是用来调用数据层。因为是User模块，主要是调用本模块内部信息管理，所以并不复杂。代码献上。

首先是接口

package cn.hncu.bookStore.user.business.ebi;import java.util.List;import cn.hncu.bookStore.user.vo.UserVO;import cn.hncu.bookStore.user.vo.UserQueryVO;public interface UserEbi {public boolean create(UserVO user);    public boolean delete(String uuid);    public boolean update(UserVO user);    public UserVO getSingle(String uuid);    public List<UserVO> getAll();    public List<UserVO> getByCondition(UserQueryVO uqm );    //TODO:user接口中的其它方法回头想到再来加}

实现层ebo 很简单基本上就是调用数据层方法

package cn.hncu.bookStore.user.business.ebo;import java.util.List;import cn.hncu.bookStore.user.business.ebi.UserEbi;import cn.hncu.bookStore.user.dao.dao.Userdao;import cn.hncu.bookStore.user.dao.factory.UserDaoFactory;import cn.hncu.bookStore.user.vo.UserQueryVO;import cn.hncu.bookStore.user.vo.UserVO;public class UserEbo implements UserEbi{    //注入DAo    Userdao dao = UserDaoFactory.getUserdao();    @Override    public boolean create(UserVO user) {        return dao.create(user);    }    @Override    public boolean delete(String uuid) {        // TODO Auto-generated method stub        return dao.detele(uuid);    }    @Override    public boolean update(UserVO user) {        // TODO Auto-generated method stub        return dao.update(user);    }    @Override    public UserVO getSingle(String uuid) {        // TODO Auto-generated method stub        return dao.getSingle(uuid);    }    @Override    public List<UserVO> getAll() {        // TODO Auto-generated method stub        return dao.getAll();    }    @Override    public List<UserVO> getByCondition(UserQueryVO uqm) {        // TODO Auto-generated method stub        return dao.getByCondtion(uqm);    }}

最后就是工厂方法

package cn.hncu.bookStore.user.business.factory;import cn.hncu.bookStore.user.business.ebi.UserEbi;import cn.hncu.bookStore.user.business.ebo.UserEbo;public class UserEbiFactory {    private UserEbiFactory(){    }    public static UserEbi getUserEbi(){        return new UserEbo();    }}
