Java中如何获得文件的物理路径

 package com.kingsoft.test; 
  import java.io.File; 
  import java.io.IOException; 
  import java.net.URL; 

  public class csDao { 
  public static void main(String[] args) { 
	  csDao getclasspath = new csDao(); 
	  	System.out.println(getclasspath.getClassPath()); 
	  	File file = new File("index.html"); 
	  try { 
	  	System.out.println("获得webroot下文件的路径"+file.getCanonicalPath()); 
	  } catch (IOException e) { 
	  	// TODO Auto-generated catch block 
	  	e.printStackTrace(); 
	  } 
  } 

 

在类中取得当前文件所在的相对路径与绝对路径

public String getClassPath() { 
  	String strClassName = getClass().getName(); 
  	String strPackageName = ""; 
	  if(getClass().getPackage() != null) { 
	  	strPackageName = getClass().getPackage().getName(); 
	  } 
	  System.out.println("ClassName:" + strClassName); 
	  System.out.println("PackageName:" + strPackageName); 
	  String strClassFileName = ""; 
	  if(!"".equals(strPackageName)) { 
	  	strClassFileName = strClassName.substring(strPackageName.length() + 1,strClassName.length()); 
	  } else { 
	  	strClassFileName = strClassName; 
	  } 
	  System.out.println("ClassFileName:" + strClassFileName); 
	  URL url = null; 
	  url = getClass().getResource(strClassFileName + ".class"); 
	  String strURL = url.toString(); 
	  strURL = "获得类的路径"+strClassFileName+"物理路径:"+ strURL.substring(strURL.indexOf('/') + 1,strURL.lastIndexOf('/')); 
	  return strURL; 
  } 
 }
