Hibernate笔记

1、

Session session =

              HibernateDataSource.getHibernateDataSource().getSession();

           String hql = "from BaseHTestPO where name = :name";

           Query query = session.createQuery(hql);

           query.setString("name", "tom");

           List<BaseHTestPO> list = query.list();

2、

String sql = "select * from htest where id=‘1‘";

           query = session.createSQLQuery(sql).addEntity(BaseHTestPO.class);

           list = query.list();

3、

HibernateDataSource.getHibernateDataSource().remove(baseScqycplxsbPO);

性能测试：

测试工具：LoadRunner 11

测试技术：采用LoadRunner Virtual User Generator 录制编写测试脚本，

然后将脚本加入LoadRunner Controller 生成客户端负载向服务器发起负载压力测试，最后结合LoadRunner Analysis监控的过程性能数据，定位问题。
