我插入数据两张表一对一的主键关联，服务器启动以后第一次可以插入数据，第二次就提示主键重复，在重启服务器以后，第一条可以插入，第二条又提示主键重复了啊！郁闷啊！！！
这是save方法，LoginId是用户名不是seq
@Transactional(propagation=Propagation.REQUIRED)
public String add(){
logger.info("add user access");
UserDAO userDao = (UserDAO)applicationContext.getBean("userDAO");
user.setLoginId(user.getLoginId());
user.setPassword(genRandomPassword(8));
user.setStatus((short)1);
user.setCategory(user.getCategory());
Date date = new Date();
user.setLastLogin(date);
individual.setCreateBy(1);
individual.setFristName(individual.getFristName());
individual.setLastName(individual.getLastName());
individual.setGreeting(mr);
individual.setCreateTime(new Date());
individual.setEmail(individual.getEmail());
individual.setEmailVerified(false);
user.setIndividual(individual);
userDao.save(user);
return "success";
}
错误异常：
