grails - 如何在Grails中访问文件系统文件夹

Question

我将一些文档上传到uploadFolder C:/ upload配置路径

environments {
    development {
        uploadFolder = "C:/upload/"
    }
    production {
        uploadFolder = "C:/upload/"

    }
    test {
        uploadFolder = "C:/Users/"
    }
}

并将其存储在 Controller 中

documentInstance.fullPath = grailsApplication.config.uploadFolder + documentInstance.filename

如何访问Grails中C:/ upload /文件中的文档？

Answer 1

在Grails中访问文件的方式与在普通Web应用程序中进行访问的方式没有什么不同。如果您的路径是绝对路径，则可以这样

def path = grailsApplication.config.uploadFolder + documentInstance.filename
File file = new File(path)

或列出上载文件夹中的所有文档

Folder dir = new File(grailsApplication.config.uploadFolder)
dir.eachFile() {File file ->  doSomething..}
