//下载已有文件
直接将超链接地址配成要下载文件地址如：下载word 文档 ：/zxks/zxksCzsm.doc
//Excle导入和导出、word导出
一、excel批量导入
1、---jsp
// 检测上传的文件的大小,类型是否正确
function checkFile(){
var filename = document.getElementById("file").value;
if("" == filename || null == filename){
alert("您还没有浏览要上传的文件！");
return false;
}else{

return false;
}
}

}
// 清空
function clear1(){

}
// 帮助
function help(){

}else{

}
}
</script>
<html:form action="/zxks/tkgl.do" method="post" styleId="form1" enctype="multipart/form-data">//一定不能忘

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。
[c1]此处索引直接对应SQL语句中的查询出的字段，第一个索引字段从1开始
