Grails或休眠不會創建缺失的表

我是新來的Grails，所以原諒我的無知 - 如果其他信息有幫助，我會盡我所能將它發佈。Grails或休眠不會創建缺失的表

我創建了一個單域模型類ToolKitComponent作爲被定義爲：

class ToolKitComponent { 
    String componentName 
    String componentVersion 
    int componentDownloads 
    Date compnentLastUpdate 

    static constraints = { 

    } 
}

我有一個控制器，我只想堅持一個例子來測試ORM，所以這裏的控制器的內容：

def index() { 
     ToolKitComponent i = new ToolKitComponent() 
     i.setComponentName("TestComponent") 
     i.setComponentVersion("v1.10") 
     i.setComponentDownloads(1) 
     i.setCompnentLastUpdate(new Date()) 
     i.save() 
}

我已經安裝了MySQL數據庫插件，並更新了我的DataSource.groovy中來：

dataSource { 
    pooled = true 
    driverClassName = "com.mysql.jdbc.Driver" 
    dialect = "org.hibernate.dialect.MySQL5InnoDBDialect" 
    loggingSql = true 
} 

// other settings 

environments { 
    development { 
     dataSource { 
      String dbCreate = "create" 
      String url = "jdbc:mysql://localhost/testDataBase" 
      String username = "myUser" 
      String password = "myPass" 
     } 
    } 
}

我創建了數據庫testDataBase並授予所有用戶名。

當我運行應用程序，我得到：

Hibernate: insert into tool_kit_component (version, compnent_last_update, component_downloads, component_name, component_version) values (?, ?, ?, ?, ?)

我使用Grails 2.0.4。

任何幫助表示讚賞！

在你的數據源定義拿走String

environments { 
    development { 
     dataSource { 
      dbCreate = "create" 
      url = "jdbc:mysql://localhost/testDataBase" 
      username = "myUser" 
      password = "myPass" 

     } 
    } 
}
