使用java SSH寫通用dao層和service層。

import java.util.List;

import java.util.Map;

public interface ICommonDao {

public Serializable save(Object entity);

public void update(Object entity);

public void merge(Object entity);

public void delete(Object entity);

public Object findObject(Class clazz, Serializable id);

public List findList(String queryString);

public List findList(String queryString, Map args);

public Object findUniqueResult(String hql);

public List findList(final String hql, final int num);

}

import java.io.Serializable;

import java.util.List;

import java.util.Map;

public interface ICommonService {

public Serializable save(Object entity);

public void update(Object entity);

public void merge(Object entity);

public void delete(Object entity);

public Object findObject(Class clazz, Serializable id);

public List findList(String queryString);

public List findList(String queryString, Map args);

public Object findUniqueResult(String hql);

public List findList(final String hql, final int num);

}

實現類，用CommonDaoImpl實現ICommonDao

用CommonServiceImpl實現ICommonService

實現的時候直接調用hibernateTemplate中的方法就行，或者自己寫點兒，都不難
