做文件上传时，在其他项目里没问题。 这个就出问题了，感觉是被struts拦截了。最开始以为是jar包冲突，后来只留了一个版本的。发现还是有这个问题。注：上传问题，没有使用struts的
代码段：
public class AServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
File tmpDir = null;//初始化上传文件的临时存放目录
File saveDir = null;//初始化上传文件后的保存目录
public AServlet() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try{
if(ServletFileUpload.isMultipartContent(request)){
DiskFileItemFactory dff = new DiskFileItemFactory();//创建该对象
dff.setRepository(tmpDir);//指定上传文件的临时目录
dff.setSizeThreshold(1024000);//指定在内存中缓存数据大小,单位为byte
ServletFileUpload sfu = new ServletFileUpload(dff);//创建该对象
sfu.setFileSizeMax(5000000);//指定单个上传文件的最大尺寸
sfu.setSizeMax(10000000);//指定一次上传多个文件的总尺寸
FileItemIterator fii = sfu.getItemIterator(request);//解析request 请求,并返回FileItemIterator集合
int i = 1;
while(fii.hasNext()){
FileItemStream fis = fii.next();//从集合中获得一个文件流
if(!fis.isFormField() && fis.getName().length()>0){//过滤掉表单中非文件域
String fileName = fis.getName().substring(fis.getName().lastIndexOf(""));//获得上传文件的文件名
fileName=i+".jpg";
BufferedInputStream in = new BufferedInputStream(fis.openStream());//获得文件输入流
BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(new File(saveDir+"/\\"+fileName)));//获得文件输出流
Streams.copy(in, out, true);//开始把文件写到你指定的上传文件夹
i++;
}
}
response.getWriter().println("File upload successfully!!!");//终于成功了,还不到你的上传文件中看看,你要的东西都到齐了吗
}
}catch(Exception e){
e.printStackTrace();
}
}
public void init() throws ServletException {
/* 对上传文件夹和临时文件夹进行初始化
*
*/
super.init();
String tmpPath = "c://tmpdir//";
String savePath = "c:///tmpdir//";
tmpDir = new File(tmpPath);
saveDir = new File(savePath);
if(!tmpDir.isDirectory())
tmpDir.mkdir();
if(!saveDir.isDirectory())
saveDir.mkdir();
}
}
