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; } }
