30 分钟不活动后 mongo DB 的套接字超时

Question

大约 30 分钟不活动后，当我尝试插入 mongo 时，我开始收到以下错误，当我再次尝试时，它开始工作。错误如下。我在 Azure 上：

[INFO ] 2018-09-10T12:00:43,188 [http-nio-8080-exec-6] connection - Closed connection [connectionId{localValue:3, serverValue:26}] to XX.XX.XX.XX:27017 because there was a socket exception raised by this connection.

[ERROR] 2018-09-10T12:00:43,189 [http-nio-8080-exec-6] [dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.mongodb.UncategorizedMongoDbException: Timeout while receiving message; nested exception is com.mongodb.MongoSocketReadTimeoutException: Timeout while receiving message] with root cause

        at java.net.SocketInputStream.read(SocketInputStream.java:141) ~[?:1.8.0_181]

这是我初始化我的 mongo 模板的方法：

@Bean

    public MongoDbFactory mongoDbFactory() {

        String[] addresses = mongoUri.split(",");

        List<ServerAddress> servers = new ArrayList<>();

        for (String address : addresses) {

            String[] split = address.trim().split(":");

            servers.add(new ServerAddress(split[0].trim(), Integer.parseInt(split[1].trim())));

        }

   

我的 mongod 版本是3.6.4并且我使用的是相同版本的 java 驱动程序。我试图增加/减少tcp_keepalive_time文档中提供的设置， sudo sysctl -w net.ipv4.tcp_keepalive_time=120但也没有帮助。

哦。所以我们发现它mongo java driver jar比我们使用的 mongo 服务器更旧，这导致了这个问题。确保驱动程序支持 mongo 服务器的版本。
