Mongodb: `com.mongodb.MongoSocketReadException: Prematurely reached end of stream` 与吗啡

Question

我有一个简单的数据结构(下面引用的 Transaction)要插入到 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。

有趣的是，我的本地开发环境(mint linux 18.1)上没有这个问题。但它无法在我的 SIT 环境(ubuntu 16.04)上运行

有什么想法吗？

更新代码以插入文档

在哪里可以找到 transactionDao.save(...) 实现:

更新2

系统可以与其他写入一起工作(即使是更大的记录)

Answer 1

大多数情况下，这是由于长时间读取\写入超时造成的。

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);
