grails - 通过 Bootstrap.groovy 向应用程序添加初始化数据

Question

我的域层看起来像这样:

@Resource(uri='/product')
class BasicProduct {

    String title
    String description
    Double price
    Date creationDate
    Date changedDate

    static constraints = {
        //everything is by default NotNull
        title(blank: false, unique: true)
        description(blank: false)
        price(blank: false, inList: [5,15,25,50,100])
        creationDate(min: new Date())
    }

}

我的 Bootstrap.groovy包含该代码:

class BootStrap {

    def init = { servletContext ->
         new BasicProduct(title: "Product1", description:"blblblblbalablablalbalbablablablablblabalalbllba", price:5).save()
         new BasicProduct(title: "Product2", description:"blblblblbalablablalbalbablablablablblabalalbllba", price:75).save()
         new BasicProduct(title: "Product3", description:"blblblblbalablablalbalbablablablablblabalalbllba", price:50).save()
         new BasicProduct(title: "Product4", description:"blblblblbalablablalbalbablablablablblabalalbllba", price:25).save()
         new BasicProduct(title: "Product5", description:"blblblblbalablablalbalbablablablablblabalalbllba", price:15).save()

         println "initializing data..."
    }

但是当我打开 \product url 我没有看到任何数据。

任何想法为什么？

我很感激你的回答!

对于您的日期，您可以执行以下操作:

Date dateCreated
Date lastUpdated 

static mapping = {
  autoTimestamp true
}
