配置baseDao（hibernateTemplate）
当用 （struts2+hibernate+spring）开发的时候，想写个baseDao,同时继承该类的Dao类能使用hibernateTemplate，
1）在baseDao中注入hibernateTemplate属性。
手动注入hibernateTemplate属性。
baseDao.java代码如下：
1 import org.hibernate.SessionFactory;
2 import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
3 import org.springframework.stereotype.Repository;
4
5 // class created by wwei 2011-11-28 下午10:12:01
6
7 @Repository("baseHibernateDao")
8 public abstract class BaseHibernateDaoImpl<T> implements BaseHibernateDao<T>{
9
10 private HibernateTemplate hibernateTemplate;
11
12 public HibernateTemplate getHibernateTemplate() {
13 return hibernateTemplate;
14 }
15 @Resource(name = "hibernateTemplate")
16 public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
17 this.hibernateTemplate = hibernateTemplate;
18 }
19
20 @SuppressWarnings("unchecked")
21 public List<T> findUser(String hql) throws Exception{
22 try{
23 return (List<T>)this.getHibernateTemplate().find(hql);
24 }catch(Exception e){
25 logger.info(e);
26 throw new Exception();
27 }
28 }
29 }
2) 继承HibernateDaoSupport类。
同时，还需要注入sessionFactory或者hibernateTemplate。
此处自定义增加了setSessionFactoryOverride方法。增加了findUser方法，实现自BaseHibernateDao接口。
1 import java.io.Serializable;
2 import java.util.List;
3
4 import javax.annotation.Resource;
5
6 import org.hibernate.SessionFactory;
7 import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
8 import org.springframework.stereotype.Repository;
9
10 // class created by wwei 2011-11-28 下午10:12:01
11
12 @Repository("baseHibernateDao")
13 public abstract class BaseHibernateDaoImpl<T> extends HibernateDaoSupport implements BaseHibernateDao<T>{
14
15 @Resource(name = "sessionFactory")
16 public void setSessionFactoryOverride(SessionFactory sessionFactory) {
17 super.setSessionFactory(sessionFactory);
18 }
19
20 @SuppressWarnings("unchecked")
21 public List<T> findUser(String hql) throws Exception{
22 try{
23 return (List<T>)this.getHibernateTemplate().find(hql);
24 }catch(Exception e){
25 logger.info(e);
26 throw new Exception();
27 }
28 }
29

31 }
