Mongodb:`com.mongodb.MongoSocketReadException:过早地到达流的末端`与morphia

Question

我有一个简单的数据结构(Transaction下面引用)插入到mongodb中:

{"amount":111,"debitAcc":"588188286231743e7d5c923d","type":"CHARGE"}

我得到以下错误堆栈:

我的mongodb版本是3.4.2.

Intereting是我在我的本地开发环境中没有问题(mint linux 18.1).但它无法在我的SIT环境中运行,这是一个ubuntu 16.04

任何的想法？

使用代码更新以插入文档

在哪里transactionDao.save(...)可以找到实施:

https://github.com/actframework/act-morphia/blob/master/src/main/java/act/db/morphia/MorphiaDaoBase.java#L206

更新2

系统可以与其他写入一起使用(即使记录更大)

Answer 1

大多数情况下,这是由于长读取/写入超时的结果.

尝试增加超时或完全删除它们:

    MongoClientOptions.Builder options_builder = new MongoClientOptions.Builder();
    options_builder.maxConnectionIdleTime(<some_long_time>);
    MongoClientOptions options = options_builder.build();
    MongoClient mongo_db = new MongoClient ("your.db.address", options);

Answer 2

我没有根本原因，但最终我通过将字段类型从 更改为BigDecimal来解决问题double。

该问题出现在我们的 SIT 环境和一位开发人员的 Windows 环境中，该环境具有 mongodb cluser 设置。
