类的方法在Grails应用程序之外使用

Question

Gails 2.4.4在Mac上运行java 7.0_25

我删除了$ HOME / .grails 在新目录中开始

• grails create-app foo
• cd foo
• 的grails
• 运行的应用程序
• create-domain-class Newtest

为此类添加了一个String

package testapp

class Newtest {

String TestString

def index() {}

static constraints = {}
}

然后我将其添加到BootStrap

class BootStrap {

def init = { servletContext ->

    new Newtest(TestString: "testme").save()

}
def destroy = {
 }
}

停止应用内
清洁
运行应用

| Running Grails application

If running in the context of a test using the mocking API or bootstrap Grails correctly.
Message: Method on class [testapp.Newtest] was used outside of a Grails application. If running in the context of a test using the mocking API or bootstrap Grails correctly.

一切都是默认的，我使用谷歌的例子来确保我已正确设置。

有人可以告诉我出了什么问题，或者这是某种错误吗？
