如何在eclipse項目中獲取和使用文件夾的路徑？

Question

我在我的eclipse項目Proj中創建了一個新文件夾Fold。如何獲得相對於Proj的摺疊路徑？該文件夾將用作存儲序列化對象的地方。我能用這個相對路徑序列化和反序列化我的代碼嗎？

Answer 1

這段代碼獲得路徑 -

String absolutePath = new File(".").getAbsolutePath(); 
System.out.println(absolutePath);// Shows you the path of your Project Folder 
int last = absolutePath.length()-1; 
absolutePath = absolutePath.substring(0, last);//Remove the dot at the end of path 
System.out.println(absolutePath); 
String filePath = "MyFolderInsideEclipseProject\\file.txt";//You know this 
System.out.println(absolutePath + filePath);//Get the full path. 

Answer 2

ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); 
URL url = classLoader.getResource("path/folder"); 

或

URL url = getClass().getResource("path/folder");
