用S2S3H4框架搭的简单登陆系统出现错误：nested transactions not supported

Question

框架sshtransactions

Answer 1

UserDaoImpl login 代码发出来看看

Answer 2

public Userinfo login(String name, String pwd) {

String str = "from Userinfo where username=? and password=?";
 Session session = sessionFactory.getCurrentSession();
 SessionFactory sf = this.getSessionFactory();
// 获取SessionFactory的会话
sf.openSession();
// 开始事务
Transaction t = session.beginTransaction();

Query query = session.createQuery(str); 
query.setString(0, name);
query.setString(1, pwd);
// 提交事务
List<Userinfo> users = query.list();
// Query.executeUpdate()方法返回的整型值表明了受此操作影响
t.commit();
session.flush();
return (users == null || users.size() == 0) ? null : (Userinfo) users
.get(0);
}

Answer 3

看你的配置好像将事务作用在了dao层，你将事务作用在service层试试吧

Answer 4

改成这样试试：
public Userinfo login(String name, String pwd) {
String str = "from Userinfo where username=? and password=?";
 Session session = sessionFactory.getCurrentSession();
Query query = session.createQuery(str); 
query.setString(0, name);
query.setString(1, pwd);
// 提交事务
List<Userinfo> users = query.list();
// Query.executeUpdate()方法返回的整型值表明了受此操作影响
return (users == null || users.size() == 0) ? null : (Userinfo) users
.get(0);
}
你已经使用aop配置了事务管理， 就不要自己写了， 直接操作session还有你把
<prop key="current_session_context_class">thread</prop>
改为
<prop key="hibernate.current_session_context_class">
org.springframework.orm.hibernate4.SpringSessionContext
</prop>

Answer 5

使用当前session 不用开启和关闭

hibernate 4的antlr-2.7.7.jar和struts2 的anltr-2.7.2.jar冲突，我把后面删了，这个错误就好啦，struts2 的anltr-2.7.2.jar是myeclips自动生成的不好删有方法，具体怎么删可以百度，反正我会了，不会的可以在帖子问我
