[2008-5-15] Spring+Struts+Hibernate(一)

环境:
系统->window2000
使用工具->Eclipse3.2(插件:MyEclipse5.0)
服务器->Tomcat5.0

主要jar文件:
Spring1.2
Hibernate3.1
JSTL.12
Struts1.2

基本架构:

com.action.UpdateAction->com.services.Services->com.dao.tabDAO

其中com.services.Services采用了事务机制

数据库(Oracle9i)文件:

create table TAB(

      TABIDvarchar2(32) primary key not null,

     TABNAME number(10)  not null

);



struts-config.xml配置:

<?xml version="1.0" encoding="UTF-8"?>

类文件:

services类:


public void update() throws Exception {

  try {

   System.out.println("services.update===============================开始");

   this.tabDAO.update();

   System.out.println("services.update===============================结束");
   throw new Exception("AAA");
  
  } catch (Exception ex) {
   throw ex;
  }

}

tabDAO类:


public void update(){

  StringBuffer sql = new StringBuffer();
  sql.append("UPDATE Tab ");
  sql.append("SET tabname = tabname + 1 ");
  sql.append("WHERE tabid = '1' ");

  this.getHibernateTemplate().bulkUpdate(sql.toString());
}


测试:

使用jmetero2.3.1

线程数:50

Ramp-UP(in seconds):0

循环次数:10

可以成功更新到500
