spring 与hibernate Annotation配置(dao)
（1）BaseDao.java
import java.io.Serializable;
import java.sql.SQLException;
import java.util.Collection;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.servlet.http.HttpServletRequest;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.HibernateCallback;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
public class BaseDao extends HibernateDaoSupport {
?private static final Log log = LogFactory.getLog(BaseDao.class);
?private SessionFactory mySessionFactory;
?
?public SessionFactory getMySessionFactory() {
??return mySessionFactory;
?}
?@Autowired
?public void setMySessionFactory(SessionFactory mySessionFactory) {
??this.mySessionFactory = mySessionFactory;
?}
?
?@PostConstruct??
?private void setSuperSessionFactory(){//BaseDao被初始化里执行这个方法
??super.setSessionFactory(mySessionFactory);
?}
?/* @Resource(name="sessionFactory")
?private void setSuperSessionFactory(SessionFactory sessionFactory){
??this.setSessionFactory(sessionFactory);
?}
?*/
?public boolean createObj(Object o) {
??boolean rtn = false;
??log.debug("开始保存实例:"+o.getClass().getName());
??try{
???HibernateTemplate ht = this.getHibernateTemplate();
???ht.save(o);
???ht.flush();
???rtn = true;
???log.debug("保存实例["+o.getClass().getName()+"]成功!");
??}catch(HibernateException e){

}

(2)CompanyDao.java
?
import org.hibernate.Session;
import org.springframework.stereotype.Repository;
import com.entry.TCompanyInfo;
?
@Repository("companyDao")
public class CompanyDao extends BaseDao {
?
}
