Question

jsp 用File 类 删除指定路径的文件 下面的代码怎么改进才能实现？？？

String addr = request.getRemoteAddr();
String path = "http://" + addr + ":8080/test/x.jpg";
System.out.println("path:" + path);
java.io.File f = new java.io.File(path);
if (f.exists()) {
System.out.println("file exists...");
f.delete();
} else
System.out.println("file not exists...");

Answer 1

path要是绝对路径才行！
String path = request.getRealPath("//");
File f = new File(path+"test/x.jpg");

Answer 2

String path="c://img/01/i.jpg";
java.io.File f = new java.io.File(path);
f.delete();

删除之前最后先判断文件是否存在
