Java Mongodb无法保持事务状态，因为缺少会话事务集合

我正在使用带有spring boot的Mongodb 4

2.1.0-M4

以下代码在我的计算机上本地工作，但在开发环境下失败：

@Transactional
public void registerNewUser(UserRegistrationForm registrationForm)
        throws IllegalArgumentException {

    validator.validate(registrationForm);

    User user = new User();
    user.setEmail(registrationForm.email);
    user.setPassword(encoder.encode(registrationForm.password));
    user.setEnabled(false);
    user.setGroups(Sets.newHashSet(ClientRoles.USER));

    User saved = userRepository.save(user);

    registrationService.sendInvitation(user.getEmail());
}

出现以下错误：

com.mongodb.MongoCommandException: Command failed with error 40527 (Location40527): 'Unable to persist transaction state because the session transaction collection is missing. This indicates that the config.transactions collection has been manually deleted.' on server mongodb-1-servers-vm-0:27017. The full response is { "operationTime" : { "$timestamp" : { "t" : 1540422989, "i" : 1 } }, "ok" : 0.0, "errmsg" : "Unable to persist transaction state because the session transaction collection is missing.

我不知道我应该尝试调试什么，或者尝试什么，这两个数据库的版本相同，并且已初始化副本集。感谢您的帮助

实际上，这个错误是不言自明的。似乎出于某种原因，

transactions

dev环境数据库中的集合被删除了。解决方法很简单：

use config
db.createCollection("transactions",{})
