第三种:URL xmlpath = this.getClass().getClassLoader().getResource("selected.txt");System.out.println(xmlpath);结果:file:/C:/Documents and Settings/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获取当前工程路径
