我很难删除文件。我将向您展示有效的方法,如果可以接受,您可以作为法官。
class StupidService{
def doThings(){
def tmpDirString = "dumpit"
def currentDir = new File("../${tempDirString}")
currentDir.eachFile(FileType.FILES){
def f=it
def answer = SuperComplicatedService.doStuff(f)
//this works, now I need to move the file to the "done" folder
File dir = new File("../${tempDirString}/done");
def endupFile = new File("../${tempDirString}/done/${f.name}")
FileUtils.copyFile(f, endupFile)
//this works; the file is copied to where I want it successfully; now I just need to delete the initial file.
def thisIsAJoke=0
while(f.delete()==false){
println "This is not a joke: ${thisIsAJoke}"
thisIsAJoke++
}
}
}
}
这样就打印出40k到150k行之间的“这不是一个 Jest :64457”等信息,然后最终删除该文件。
到底是怎么回事?
最佳答案
SuperComplicatedService.doStuff(f)
是做什么的?如果打开文件,请确保在返回之前将其关闭。否则,您将无法删除文件,除非垃圾收集器收集了引用该文件的对象。
