项目笔记：分层模型建立

action、service、dao层建立：

1、action层：继承自  BaseAction

注意：（1）导入的service和声明的实体类或变量，均需要get和set才能获取到；

（2）实体类前不能加@Resource，否则会报错。

 

 

public class GenuineSerialNumberManagementAction extends BaseAction {
    private static final long serialVersionUID = -3616113266159998137L;

    @Resource
    private GenuineSerialNumberManagementService genuineSerialNumberManagementService;

    private GenuineSerialNumberManagement genuineSerialNumberManagement;    

    //与页面相关的都在此层设计
}

2、service层：通常包含2块：

一块声明service类，继承自  BaseService  ，如下：action里面需要调用service层的类，均要在此先声明定义

public interface GenuineSerialNumberManagementService extends BaseService<GenuineSerialNumberManagement> {
    
    public GenuineSerialNumberManagement queryBySoftDisplayName(String softDisplayName);

    @Override
    void save(GenuineSerialNumberManagement entity);
    
    void createXML();

    public String importTemplate(File file);

　　//action层里要调用service层的方法，均要在此先声明定义

}

另一块service实现类，继承自  BaseServiceImpl  和  GenuineSerialNumberManagementService ，service层定义的方法，均要在此实现类层进行方法实现。

@Service("genuineSerialNumberManagementService")
@Transactional
public class GenuineSerialNumberManagementServiceImpl extends BaseServiceImpl<GenuineSerialNumberManagement> implements GenuineSerialNumberManagementService {

    protected GenuineSerialNumberManagementDao genuineSerialNumberManagementDao;
    
    public GenuineSerialNumberManagementDao getGenuineSerialNumberManagementDao() {
        return genuineSerialNumberManagementDao;
    }

    @Resource(name="genuineSerialNumberManagementDao")
    public void setGenuineSerialNumberManagementDao(GenuineSerialNumberManagementDao genuineSerialNumberManagementDao) {
        this.genuineSerialNumberManagementDao = genuineSerialNumberManagementDao;
        this.baseDao = genuineSerialNumberManagementDao;
    }
　　//service层定义的方法，均要在此实现类层进行方法实现

}

3、dao层：也分2块：此层是写与数据库进行交互的方法

一块dao类：继承自  BaseDao，在serviceImpl实现类层调用的与数据库交互的方法，均要在此层先声明定义

public interface GenuineSerialNumberManagementDao extends BaseDao<GenuineSerialNumberManagement> {

    public GenuineSerialNumberManagement queryBySoftDisplayName(String softDisplayName);

    @Override
    void save(GenuineSerialNumberManagement entity);

    List<GenuineSerialNumberManagement> queryByType(Integer type);

    List<GenuineSerialNumberManagement> queryBySoftIdAndType(Integer softId, Integer type);
    
    List<GenuineSerialNumberManagement> queryBySoftId(Integer softId);
    // 在serviceImpl实现类层调用的与数据库交互的方法，均要在此层先声明定义

}

一块dao实现类：继承自BaseDaoImpl  和 GenuineSerialNumberManagementDao ， dao层定义的方法，均要在此层进行方法实现

@Repository("genuineSerialNumberManagementDao")
public class GenuineSerialNumberManagementDaoImpl extends BaseDaoImpl<GenuineSerialNumberManagement> implements GenuineSerialNumberManagementDao {

    @Override
    public GenuineSerialNumberManagement queryBySoftDisplayName(String softDisplayName) {
        return (GenuineSerialNumberManagement) getSession().createQuery(" from "+this.clazz.getName()+" this where this.softDisplayName=:softDisplayName ")
                .setParameter("softDisplayName", softDisplayName)
                .uniqueResult();
    }
    @Override
    public void save(GenuineSerialNumberManagement entity) {
        super.save(entity);
    };
    @SuppressWarnings("unchecked")
    @Override
    public List<GenuineSerialNumberManagement> queryBySoftIdAndType(Integer softId,Integer type) {
        return this.getSession().createQuery(" FROM " + this.clazz.getName() + " this WHERE this.softId =(:softId) AND this.type =(:type)")
                .setParameter("softId", softId)
                .setParameter("type", type)
                .list();
    }
　　//dao层定义的方法，均要在此层进行方法实现
}
