mongodb - MongoTimeoutException 消息 : Timed out while waiting to connect after 10000 ms

Question

我在 grails 中使用 gorm 连接到 MongoDB。我收到 MongoTimeOutException。我能够使用 mongo java 驱动程序独立程序成功连接到 MongoDb。为什么我无法通过 Grails GORM 插件连接？

有人可以帮忙吗？下面是配置

grails {
    mongo {
      host = "localhost"
      port = 27107
      databaseName = "test"
     options{
         connectionsPerHost=20
     }
    }
  }

下面是领域类

class Device {


    String deviceType
    String deviceId
    int primary

    static constraints = {

    }
}

下面是异常trace

| Error 2014-11-09 16:10:39,620 [http-bio-8080-exec-4] ERROR errors.GrailsExceptionResolver  - MongoTimeoutException occurred when processing request: [GET] /devices/Device

Timed out while waiting to connect after 10000 ms. Stacktrace follows:

或者有人可以分享带有 GORM 支持的示例 Grails 示例吗？我基本上是这个 Grails 的新手。

我想通了这个问题。这是我的错，因为端口号是 27107 而不是 27017，我花了一天时间才弄明白。哈哈
