JPA循环中的事务问题求教！！

// Excel批量导入用户数据 @Transactional(readOnly = false) public String importByExcel(File file,String createPerson) { String checkUsercode = "^[a-zA-Z][a-zA-Z0-9_]{5,15}$"; // 用户名正则验证 String checkEmail = "[a-z0-9-.]{1,30}@[a-z0-9-]{1,65}.(com|net|org|info|biz|([a-z]{2,3}.[a-z]{2}))"; // 邮箱正则验证 try { String[][] result = ExcelOperateSimple.getData(file, 0); int suc = 0; //成功条数 int totle=result.length-1; //总条数 for (int i = 1; i < result.length; i++) { User user = new User(); user.setUsercode(result[i][0]); user.setPassword(result[i][1]); user.setUsername(result[i][2]); user.setEmail(result[i][3]); user.setCreatePerson(createPerson); user.setCreatetype("import"); user.setCreateTime(DateSimple .getCurrentDateString("yyyy-MM-dd hh🇲🇲ss")); List<User> list_usercode = regDao.findByUsercode(user .getUsercode()); List<User> list_email = regDao.findByEmail(user.getEmail()); result[i][4] = ""; if (!Pattern.compile(checkUsercode).matcher(user.getUsercode()).matches()) { result[i][4] += "用户名不合法！"; } if (list_usercode.size() != 0) { result[i][4] += "用户名已被占用！"; } if (!Pattern.compile(checkEmail).matcher(user.getEmail()).matches()) { result[i][4] += "电子邮箱地址不合法！"; } if (list_email.size() != 0) { result[i][4] += "电子邮箱地址已被占用！"; } if(StringSimple.equals(result[i][4],"")){ // user.setUsercode(result[i][0]); // user.setPassword(result[i][1]); // user.setUsername(result[i][2]); // user.setEmail(result[i][3]); user.setIspass("1"); user.setIsstop("0"); regDao.save(user); result[i][4]="导入成功！"; suc+=1; } } // for (int i = 1; i < result.length; i++) { // // } ExcelOperateSimple.write(result,"d:\\aa.xls"); return "共导入"+totle+"条数据，成功"+suc+"条！"; } catch (Exception e) { e.printStackTrace(); return "系统错误！"; } } 代码如上，大概就是这个问题。excel批量导入用户数据，先校验再插入，我如果把save方法写在另外一个循环里，程序就没有问题（下面注释掉的循环里），但是如果直接写在上面，就会报错，是不是事务上出了什么问题，因为我单步调试，第一次的insert语句直到第二次查询的时候后台才打印出来。 错误信息：
