【问题描述】：

在 grails 2.4.4 中创建了一个新应用，并创建了一个控制器和 gsp 文件。在开发运行模式下，我正在更改代码-gsp 文件更改反映在浏览器中，但没有反映在控制器代码中，但在这两种情况下，我都会收到消息

在 index.gsp 中添加了一行：

Click

创建的控制器名称 Student

打包 project.bidesi.check 类 StudentController def index()

def blankAction()
    render(view:"/student/blankAction", model:[mineData:"ppppp"])

创建的 gsp 名称空白Action.gsp

示例标题

样品线

$mineData

所以当我在控制器中更改 mineData 的值时，它不会反映在 gsp 中，但在输出提示中我收到如下消息：

| Server running. Browse to http://localhost:8080/checkNew
| Compiling 1 source files.

即使我尝试使用命令

grails -reloading run-app

但它没有帮助。

【问题讨论】：

请提供一个完整的例子。或者至少是控制器以及没有拾取哪些更改。

添加了控制器和gsp代码

【参考方案1】：

看来您的问题出在 grails.project.fork 设置中。我建议按照此处Grails 2.3.0 Auto-reloading not working

明确设置您的分叉设置
