Question

据我所知，我们总是从assets/image文件夹中显示图像比如像..

<asset:image src='settings.png' style="height: 20px" alt="logout"/>

但是我的图片文件如何位于根目录中？喜欢

/home/file/images.png -->my image's file /root/tomcat8/webapp/alkd.war

home和root文件夹属于同一级别

我正在使用grails 3.1.1

我正在尝试显示超过10张图片

我试图像这样添加一些代码applicaiton.yml ..

但我在启动时遇到此错误..

`ERROR org.springframework.boot.SpringApplication - Application startup failed

Answer 1

您可以从获取Tomcat root并附加目录/文件名开始，例如

ggplot2 2.2.0

Answer 2

根据official docs：

从外部存储目录提供资产

可以将资产管道配置为将资产文件复制到外部存储路径。这对于设置您的Web服务器（例如nginx）以直接为您的静态资产提供服务非常有用。为此，只需在Config.groovy环境块中定义一个配置变量。
environments {
    production {
        grails.assets.storagePath = "/full/path/to/storage"
    }
}
还可以配置自定义CDN资产URL以提供这些资产：
environments {
        production {
            grails.assets.url = "http://s3.amazonaws.com/asset-pipe/assets/"
        }
    }
