如何Grails的

Question

訪問文件系統文件夾我上傳一些文件到uploadFolder C：/上傳配置路徑

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

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

，我把它存儲在控制器

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

如何訪問Grails中C：/ upload/file中的文檔？

Answer 1

您在Grails中訪問文件的方式沒有任何差異，然後在普通Web應用程序中如何執行。如果你的路徑是絕對路徑，你可以像這樣

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

，或者列出文件夾上傳

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