Struts2+spring+hibernate框架

SSH在J2EE开发中有个广泛的应用，下面就是我在具体代码，请大家参考，如果有错误也希望大家能指出:

1.BaseDao:数据库原子方法的接口类,列出基本方法，大家可以完善:

public interface BaseDAO extends Serializable{

public Serializable save(BaseDomain domain);  

public void update(BaseDomain domain);

public void delete(BaseDomain domain);    

public BaseDomain findByID(String entityName, Serializable id);

public BaseDomain get(Class claz,Serializable id) throws Exception;

public int getRecordCountByHqlQuery(String hql) ; 

public List findColsByHqlQuerySupportPaging(final String hql, final int start, final int reCount);  

}

2.BaseDaoImpl:具体实现类

public class BaseDAOImpl extends HibernateDaoSupport implements BaseDAO {

    public Serializable save(BaseDomain domain) {
        return getHibernateTemplate().save(domain);
    }

    public void update(BaseDomain domain) {
        getHibernateTemplate().update(domain);
    }

    public void delete(BaseDomain domain) {
        getHibernateTemplate().delete(domain);
    }

    public BaseDomain findByID(String entityName, Serializable id) {
        return (BaseDomain) getHibernateTemplate().get(entityName, id);
    }

    public List findColsByHqlQuerySupportPaging(final String hql,final int start, final int reCount) {

         List resultList = getHibernateTemplate().executeFind(new HibernateCallback(){

         public Object doInHibernate(Session session)  
                    throws HibernateException, SQLException {

                 Query query = session.createQuery(hql);  
                 query.setFirstResult(start*reCount);  
                 query.setMaxResults(reCount);                     
                  return query.list();  

                }                 
        });  
       return resultList;  }

     public int getRecordCountByHqlQuery(String hql) {  
        int recordCount = Integer.parseInt(String.valueOf(getHibernateTemplate().find(hql).get(0)));
        return recordCount;       
     }

     public BaseDomain get(Class claz, Serializable id) throws Exception {
          return (BaseDomain) getHibernateTemplate().get(claz, id);
    }

}

3.BaseService:业务层的接口方法。

public interface BaseService{}

4.BaseServiceImpl:业务层具体实现类，注入baseDao,代码如下:

public class BaseServiceImpl implements BaseService {

    protected BaseDAO baseDao;
    public BaseDAO getBaseDao() {
        return baseDao;
    }

    public void setBaseDao(BaseDAO baseDao) {
        this.baseDao = baseDao;
    }

}

5.BaseDomain:所有pojo的基类

public abstract class BaseDomain  implements java.io.Serializable{ }

6.BaseAction:Struts2的基类，所有action都继承它，提供了request,reponse,session等属性。

public class BaseAction extends ActionSupport implements ServletRequestAware,ServletResponseAware,SessionAware {
    protected HttpServletRequest request = null;
    protected HttpServletResponse response = null;
    protected Map session;   
    protected String message;

    public void sendJsonString(String json){
        response.setContentType("text/html;charset=UTF-8");
        response.setHeader("Cache-Control", "no-cache");
        try {
            PrintWriter out = response.getWriter();
            out.print(json);
            out.flush();
            out.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   
    }   

    public void setServletRequest(HttpServletRequest request) {
        this.request = request;
    }

    public void setSession(Map session) {
        this.session = session;
    }

    public void setServletResponse(HttpServletResponse response) {
        // TODO Auto-generated method stub
        this.response = response;
    }

    public int getCurrentPage() {
        int currentPage = 0;
        Enumeration paramNames = request.getParameterNames();
        while (paramNames.hasMoreElements()) {
            String name = (String) paramNames.nextElement();
            if (name != null && name.startsWith("d-") && name.endsWith("-p")) {
                String pageValue = request.getParameter(name);
                if (pageValue != null) {
                    currentPage = Integer.parseInt(pageValue) - 1;
                }
            }
        }
        return currentPage;
    } //displaytag翻页处理，得到当前页码

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}
