Связь с Grails с базой данных DB2

Question

Я пытаюсь подключить приложение grails к базе данных DB2, которая работает локально. Когда я хочу запустить приложение, я получаю многократные ошибки? Я только начинаю работать над grails и даже больше об управлении базами данных DB2. Кто-нибудь может мне помочь ?

Вот ошибка тропы

и в моем файле DataSource.groovy, вот что я изменил:

environments { 
    development { 
     dataSource { 
      dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', '' 
      //url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000" 
      url = "jdbc:db2://localhost:50000/DTH3_E:currentSchema=DFP_V115" 
     } 
    } 
.... 

С некоторых исследований, я понял, что это был мой спящий режим конфигурации. Может ли кто-нибудь (в) проверить? И куда я иду дальше ... довольно потеряно, чтобы сказать меньше

Если интересно, база данных запущена и я могу подключиться к ней с помощью DbVisualizer.

Заранее благодарим за помощь! Если вам нужна дополнительная информация, спросите :) Я постараюсь как можно подробнее разъяснить проблему.

Answer 1

Из вашего исключения Grails пытается использовать драйвер H2 JDBC для подключения к вашей базе данных DB2. Попробуйте указать диалект DB2 Hibernate в вашем dataSource декларации, чтобы увидеть, если он будет использовать правильный драйвер:

dataSource { 
    dialect="org.hibernate.dialect.DB2Dialect" 
} 

Кроме того, убедитесь у вас есть необходимый DB2 баночку в проекте вы Grails.
