我在 Grails 上使用 Groovy 并且配置了资源插件。我有这种情况：

  • 我有一个产品，它有多个图像。

  • 管理员可以删除任何图像。

逻辑是，当管理员单击“删除”时，我会从文件系统中删除文件（及其拇指文件）。

整个过程运行顺利，但过了一段时间（5-6分钟），当资源插件再次刷新它的资源时，它会抛出一个错误，“some module depends on resource [path/to/file] but the file没找到”。

堆栈跟踪如下：

资源插件期望模块中的底层文件不会改变。此外，应用程序直接链接的任何静态资产（而不是通过模块或 <g:resource> 标签）都被认为是ad-hoc 的，并作为模块添加到资源上下文中。这甚至允许资源插件对这些“遗留”资产进行缩小、编译、缓存等。

如果您使用文件系统来交付您的这些有些动态的资产，最好将它们排除在资源插件的临时处理之外。设置配置标志grails.resources.adhoc.excludes以排除您存储这些资产的任何目录。
