为什么在开发我的grails插件时集成测试中的依赖注入失败了

当使用生成的集成测试（grails create Integration test package.ServiceName）时，我无法在测试中使用注入的服务-在grails插件中

它抛出了一个非常无用的NullPointerException

但是，在grails应用程序（grails创建应用程序）中使用的相同过程完全没有问题

您可以通过以下方式进行复制：

>grails创建插件myServicePlugin

>grails测试应用程序

//按预期通过

>grails创建服务测试。DummyService

Alter

\myServicePlugin\test\unit\testing\dummmyServiceSpec.groovy

改变

到

>grails测试应用程序

//通过

>grails创建集成测试testing.DummyService

Alter

\myServicePlugin\test\integration\testing\dummmyServiceSpec.groovy

改变

到

>grails测试应用程序集成：

//按预期通过

到目前为止一切都很好。现在编辑

DummyService

来做点什么。。虚幻的

Alter

\myservicecplugin\grails app\services\testing\DummyService.groovy

加

在

defservicemethod（）{}

现在将服务注入测试规范

Alter

\myServicePlugin\test\integration\testing\dummmyServiceSpec.groovy

添加

def dummyService

下面

并将

“测试某物”

方法主体更改为：

expect:
    assert dummyService.dummySpit()

这就是世界崩溃的地方

在某个阶段，

create plugin

malarkey已经停止将hibernate作为依赖项

如果您将hibernate作为依赖项重新添加，则应该运行上面的集成测试。 即

Alter

\myServicePlugin\grails app\conf\BuildConfig.groovy

将

runtime:hibernate:3.6.10.7“

添加到

plugins{}

块

注意：考虑到@dmahapatro的回答，最好不要导出hibernate插件。因此，要避免这种情况，您可以：

test (":hibernate:3.6.10.7"){
    export = false
}

您不应该这样做。@dmahapatro如果插件包含在

测试

范围和

export=false

中，您是否同意该解决方案？如果我是您，我不会仅用于通过测试，除非有要求。：）这取决于你的使用情况，如果没有任何问题，你可以继续。我知道这是我的第一篇SO帖子。。但是为什么在这个问题上投反对票呢？我能理解投票否决一个答案。。。但问题是什么？有什么问题吗？通过删除琐碎内容并强调问题的要点来编辑问题。DummyServiceSpec的第22行是什么？
