【问题描述】：

我正在使用grails 2.3.4。当我加载我的 index.gsp 页面时，我得到：

| Server running. Browse to http://localhost:8080/testApplication
| Application loaded in interactive mode. Type 'stop-app' to shutdown.
| Enter a script name to run. Use TAB for completion:

我的index.gsp 看起来很简单：

<head ng-app> 
<meta name="layout" content="main" />
<title>Title Page</title>

<!-- here we are loading angularjs -->
<r:require module="angular" />

</head>
<body>
    <div>
        <div>Hello World!</div>
        <p>Nothing here {{'yet' + '!'}}</p>
        <p>1 + 2 = {{ 1 + 2 }}</p>
    </div>
</body>

我的URL mapping 看起来像这样：

class UrlMappings {

    static mappings = {
        "/api/product"(resources:"product")
        "/$controller/$action?/$id?(.${format})?"{
            constraints {
                // apply constraints here
            }
        }

        "/"(view:"/index")
        "500"(view:'/error')

    }
}

为什么会出现此错误？我真的很感谢你的回答！

更新

我的ApplicationResources.groovy 文件：

modules = {

    'angular' {
        resource url:'/js/lib/angular-1.2.8/angular.min.js'
        resource url:'/js/lib/angular-1.2.8/angular-resource.min.js'
        println "Loading libs"
    }

}

这就是我的文件夹结构：

【问题讨论】：

检查 angular.js 是否正确加载。估计js加载有问题。
你有在 ApplicationResources.groovy 中定义的角度模块吗？对吗？
并将 ApplicationResources 文件的内容放入您的问题中
@AramArabyan 请看我的更新！
也试过了，但结果和以前一样......

【解决方案1】：

它说异常 在属性名称 (ng-app) 后需要 '='。为什么将“ng-app”放在“head”标签中？尝试删除它。

【讨论】：

感谢您的回答！但是，将它放入我的<div> 不会使用 angularjs。我只是得到普通的html output，它不是由angularjs 呈现的。
尝试将 ng-app 放到你的 html 标签中。
