Как использовать mongodb с grails 2.4.4?

Question

Я пытаюсь использовать mongodb с grails. Для этого добавьте следующий код в плагине части в BuildConfig.groovy

compile ":mongodb:3.0.3" 

Тогда я изменил DataSource.groovy в follwings:

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

Но это вызывает ошибку компиляции, как следующие:

Не могли бы вы рассказать мне, как исправить ошибку. Кстати, учебник, что я следовал, можно найти в ссылке ниже: http://blog.mongodb.org/post/18510469058/grails-in-the-land-of-mongodb

Answer 1

ваш сервер недоступен, то, что вы можете ясно видеть в трассировке исключения:

причиненного MongoTimeoutException: Таймаут во время ожидания сервера, который соответствует AnyServerSelector {} через 10000 мс

Answer 2

Так вот что происходит:

Прежде всего вы должны подтвердить, если ваш монг o работает только путем ввода команды mongo (и посмотреть, приземлитесь ли вы на монгольскую оболочку) или на ps -A | grep mongod.

В любом случае, если служба MongoDB запущена, вам сначала нужно начать обслуживание.

sudo service mongod start # Для Ubuntu & CentOS
# ИЛИ
mongod --config /etc/mognod.conf

(Я дал вам пример для Ubuntu & CentOS. Read this если вы используете другую операционную систему.)

Теперь, после того, как вы начали службу или подтвердили, что сервер MongoDB работает &, вам нужно выполнить run-app.

Одна вещь, которую я видел в вашем вопросе в номере порта, например, 27107, а не 27017. Я не уверен, что это по ошибке в вопросе, или вы добавили это в свой файл Grails DataSource.groovy. По умолчанию MongoDB запускается на номер порта 27017 (хотя вы можете его настроить). Так что это может быть вашей проблемой.

Поэтому измените этот номер порта на 27017, а затем выполните grails run-app. Это должно сработать.
