java - 关于OpenLRW部署到mongo docker实例时出现异常

Question

已解决:

我必须在没有 --auth 的情况下运行 docker 镜像...

$ docker run -ti --rm -p 30000:27017 -v /srv/mongo:/data/db -e MONGOD_OPTIONS='--nojournal --smallfiles --noprealloc' arkadi/mongodb /sbin/my_init -- bash -l

我需要实现一个学习记录存储(LRS)，能够使用 java 或 scala 将数据保存到 cassandra 实例中。我找到了这个项目，https://github.com/Apereo-Learning-Analytics-Initiative/OpenLRW它使用 mongo 2.6 作为主要后端，并使用 java8 和 spring-boot 编写。

这看起来是一个很好的起点，我只需将 cassandra 集成为新的依赖项，构建一些连接器，但是当我第一次尝试运行时，我收到了一个异常:

这是full stacktrace

我这样运行 mongo 实例:

$ docker run -ti --rm -p 30000:27017 -v /srv/mongo:/data/db -e MONGOD_OPTIONS='--nojournal --smallfiles --noprealloc --auth' arkadi/mongodb /sbin/my_init -- bash -l

mongo docker实例的ip是:

root@4b190dded9e7:/# ifconfig
eth0      Link encap:Ethernet  HWaddr 02:42:ac:11:00:03  
      inet addr:**172.17.0.3**  Bcast:0.0.0.0  Mask:255.255.0.0

      RX bytes:4500 (4.5 KB)  TX bytes:0 (0.0 B)

我可以从本地主机访问此 docker 实例:

$ ping 172.17.0.2

这就是我实际的 application.yaml 文件的样子:

matthews.users:

 adminuser : ${random.value}

 emailAddress: ${random.value}@unicon.net
 

我使用以下命令运行该项目:

`mvn clean package spring-boot:run` 

看起来我必须在运行 jar 文件之前在 mongo 实例中执行其他操作，不是吗？

非常感谢。

您似乎正在尝试连接到使用无需用户名和密码的身份验证的 mongodb 实例。

你应该尝试:

• 向您的配置文件提供用户名和密码以提供凭据
• 如果是开发环境，请禁用身份验证并测试您的应用程序是否连接到 mongod 实例
