String courseFile = directory.getCanonicalPath() ;
System.out.println(courseFile);结果:C:\Documents and Settings\Administrator\workspace\projectName
获取当前类的所在工程路径;第三种:URL xmlpath = this.getClass().getClassLoader().getResource("selected.txt");
System.out.println(xmlpath);结果:file:/C:/Documents%20and%20Settings/Administrator/workspace/projectName/bin/selected.txt
获取当前工程src目录下selected.txt文件的路径第四种:System.out.println(System.getProperty("user.dir"));结果:C:\Documents and Settings\Administrator\workspace\projectName
