Question

我一直在尝试使用mongodb和grails。为此，请在BuildConfig.groovy

的插件部分中添加以下代码

compile ":mongodb:3.0.3"

然后我将DataSource.groovy更改为以下内容：

          grails {
            mongo {
              host = "localhost"
              port = 27107
              username = "user"
              password="secretpassword"
              databaseName = "physicians"
            }
          }

但它会导致编译错误如下：

你能告诉我如何修复错误吗？顺便说一句，我一直关注的教程可以在下面的链接中找到： http://blog.mongodb.org/post/18510469058/grails-in-the-land-of-mongodb

Answer 1

您的服务器无法访问，您可以在异常跟踪中清楚地看到：

由MongoTimeoutException引起：在10000毫秒后等待与AnyServerSelector {}匹配的服务器时超时

Answer 2

所以这就是发生的事情：

首先，只需输入mongo命令（并查看是否登陆Mongo shell）或ps -A | grep mongod确认您的Mongo服务是否正常运行。

在任何情况下，如果MongoDB服务正在运行，那么您首先需要启动服务。

sudo service mongod start＃对于Ubuntu＆amp; CentOS的
＃或
mongod --config /etc/mognod.conf

（我已经为您提供了Ubuntu和CentOS的示例。如果您使用不同的操作系统，请阅读this。）

现在，在您开始服务或确认MongoDB服务器启动后＆amp;你需要做run-app。

我在端口号中看到问题的一件事，即27107而不是27017。我不确定问题是否是错误的，或者您已将其添加到Grails DataSource.groovy文件中。默认情况下，MongoDB在端口号27017上运行（尽管您可以配置它）。所以这可能是你的问题。

然后将该端口号更改为27017，然后执行grails run-app。这应该有用。

如何使用mongodb与grails 2.4.4？
