java - Mongodb 无法持久化事务状态，因为 session 事务集合丢失

Question

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运行，但在开发环境中失败:

@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" : { "$timestamp" : { "t" : 1540422989, "i" : 1 } }, "ok" : 0.0, "errmsg" : "Unable to persist transaction state because the session transaction collection is missing. This indicates that the config.transactions collection has been manually deleted.", "code" : 40527, "codeName" : "Location40527", "$clusterTime" : { "clusterTime" : { "$timestamp" : { "t" : 1540422994, "i" : 1 } }, "signature" : { "hash" : { "$binary" : "AAAAAAAAAAAAAAAAAAAAAAAAAAA=", "$type" : "00" }, "keyId" : { "$numberLong" : "0" } } } } at 

我不知道应该尝试调试什么，或者尝试什么，两个数据库都是相同的版本并且已初始化副本集。任何帮助表示赞赏。

实际上，这个错误是不言自明的。似乎由于某种原因，开发环境数据库中的 transactions 集合已被删除。修复方法很简单:

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