1、第一种:
File inFile = new File(downfileA);//downfileA是前台传过来的,文件路径
String fileName = inFile.getName();
String path = request.getSession().getServletContext().getRealPath("/");
File outFile = new File(path);
FileUtils.copyFile(new File(fileName), outFile);
2、第二种:
InputStream is = null;
OutputStream os = null;
byte[] number = new byte[1024];
try
{
File inFile = new File(downfileA);//downfileA是前台传过来的,文件路径
String fileName = inFile.getName();
String path = request.getSession().getServletContext().getRealPath("/")+fileName;
is = new BufferedInputStream(new FileInputStream(downfileA), 1024);
os = new BufferedOutputStream(new FileOutputStream(path),1024);
while(is.read(number) > 0)
{
os.write(number);
}
os.close();
is.close();
}
catch (Exception ex)
{
ex.printStackTrace();
}
注:上述两种方法在linux下不好用。会提示找不到路径。
3、在linux下通过servlet的方式解决。(有时间再补充)
