在线等:求救如何解决:don't flush the Session after an exception occurs的方法

Question

更新多条记录出错:Hibernate.在线等....
试图在一个Action中调用多次Hibernate插入数据,
因为插入前一条数据后在后一条插入数据中需要用到前一条的记录.
代码如下:
public ActionForward regUser(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
UserActionForm uaf = (UserActionForm)form;
//取出从页面提交过来的数据
String name = uaf.getName();
String password = uaf.getPassword();
String password1 = uaf.getPassword1();
String nichen = uaf.getNichen();
String email = uaf.getEmail();
String province = uaf.getProvince();
String sex = request.getParameter("sex");
MD5 md5 = new MD5();
//将页面提交过来的数据设置进User类中
User user = new User();
user.setName(name);
user.setEmail(email);
user.setPassword(md5.getMD5ofStr(password));
user.setNichen(nichen);
user.setSex(sex);
user.setProvince(province);
user.setRegTime(new java.sql.Timestamp(System.currentTimeMillis()));
//调用业务逻辑方法
int flag = 0;
try {
flag = userManager.add_User(user);
}catch(Exception e){
e.printStackTrace();
return mapping.findForward("add_fail");
}

/**
 * 默认的方法是开通博客同时是发表一篇开通博客的日志.
 */
Blog blog = new Blog();
blog.setName(name);
blog.setVisited(1);
blog.setGrade(1);
blog.setOnline(true);
blog.setUser(user);
blog.setLastLoginTime(new java.sql.Timestamp(System.currentTimeMillis()));
blog.setMingyuan("OpenSource社区博客中心欢迎你");
blog.setHead(null);

/**
 * 发表一篇开通博客的日志...
 */
Daily daily = new Daily();
daily.setTitle("用户"+user.getName()+"开通博客--"+name);
daily.setContent("<font size='4'><p>感谢用户:<font color='white' size='3'>"+user.getName()+"</font>在OpenSource开源社区中心开通博客</p>" +
"<p>若有任何问题及意见,请发邮件到*****@163.com或者致电到:*****或者QQ交谈:******</p>" +
"<p>如果发生问题,我们会尽快帮你解决你所提出的问题,你的意见及问题是我们开源社区前进的动力!</p>"+
"<p>谢谢你的合作!</p></font><p align='right'>开发团队PPP敬上!</p>");
daily.setVisited(0);
daily.setPostTime(new java.sql.Timestamp(System.currentTimeMillis()));
int flag2 = 0;
try {
flag2 = blogManager.add_Blog(blog);
}catch(Exception e){
e.printStackTrace();
return mapping.findForward("add_fail");
}
daily.setBlog(blog);
try {
dailyManager.add_Daily(daily);
}catch(Exception e){
e.printStackTrace();
return mapping.findForward("add_fail");
}
if(flag==1 && flag2==1){
return mapping.findForward("add_success");
}else {
return mapping.findForward("add_fail");
}
}

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.16 logs.这种问题的解决方法,在网上搜了一下,找不到适当的方法.国外的论坛也进了好几个.都没有合适的.
我是要在SSH集成中用到,不是在测试类用..!!

Answer 1

       HiberDb hdb = new HiberDbImpl();//hibernate实现类
   hdb.setAutocommit(true);
       hdb.hdbCommit();

Answer 2

我在Action中怎么设置啊?老兄..Struts中

Answer 3

在Hibernate中也可配置:
自动提交事务
<property name="connection.autocommit">true</property>也可以底层手动配置
Session session=getSession();
开启事务 session.beginTransaction();
提交事务 session.beginTransaction().commit();
