如下代码：
（注意该类继承自HibernateDaoSupport ,要在applicationContext.xml中将sessionFactory注入此类中）
public class DaoUtil extends HibernateDaoSupport {
public Object executeMySQL(final String sql){
System.out.println(sql);
return getHibernateTemplate().execute( new HibernateCallback(){
public Object doInHibernate(Session session)
throws HibernateException, SQLException {
Connection CurConn = session.connection();
PreparedStatement ps = CurConn.prepareStatement(sql);
ps.execute();
ps.close();
session.flush();
return null;
}
} );
}
public Object executeBetchSQL(final ArrayList sqlList){
return getHibernateTemplate().execute( new HibernateCallback(){
public Object doInHibernate(Session session)
throws HibernateException, SQLException {
Connection CurConn = session.connection();
int count = sqlList.size();
for(int i=0;i//System.out.println(sqlList.get(i));
PreparedStatement ps = CurConn.prepareStatement(sqlList.get(i));
ps.execute();
ps.close();
session.flush();
}
return null;
}
} );
}
public static DaoUtil getFromApplicationContext(
ApplicationContext ctx) {
return (DaoUtil) ctx.getBean("DaoUtil");
}
}
