struts2_hibernate3.3小例子 不报错 但数据库没反应 小项目在我的资源里面
本帖最后由 yjb8646226 于 2012-11-27 18:46:11 编辑 数据库 sqlserver 数据库名hibernate 建一个person表 5个字段 id username password age registerDate
熟悉struts2 hibernate的大神帮忙分析下
项目在我的资源里面可以下载
[最优解释]
提交代码也OK的！！！
不报错、数据库没反应就是没有添加到数据！！！
你看看有没有打印sql呢？
try {
session.save(person);
tx.commit();
} catch (Exception e) {
if(tx!=null){
tx.rollback();
}
}finally{
HibernateUtil.close(session);
}
this.registerDate = registerDate;
}
}

//把页面的值放到person里面

//通过PersonService借口实例化一个对象把person对象的值存入数据库

[其他解释]
1.sql没有打印出来 原因未知
2.log4j:WARN No appenders could be found for logger (com.opensymphony.xwork2.config.providers.XmlConfigurationProvider).
log4j:WARN Please initialize the log4j system properly.
启动tomcat会有这两句
3.我把文件上传到了我的资源里面 你能不能帮我分析一下
