UserAction：

import org.springframework.orm.hibernate3.HibernateTemplate;

import com.sun.java.entity.User;

public class UserDao {
private static Log log = LogFactory.getLog(UserDao.class);
private HibernateTemplate hibernateTemplate;

public void save(User u) {
log.info("保存用户");

log.info("注册成功！");
}

public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
}

[解决办法]
如果不报错，那可能是事务没提交，你添加一个声明式事务试试。。
[解决办法]
你这应该是配置问题，楼上说的不错，你spring没加事务呀，如果还是不行，那你得看看其它的配置了
