采用的是axis2 webservice 上传文件到服务端,开始采用图片,可是通了,本以为ok了,可是换成其他格式就抛出异常了:
     name:null
type:text/plain
size:0
java.lang.NullPointerException
at java.util.regex.Matcher.getTextLength(Unknown Source)
at java.util.regex.Matcher.reset(Unknown Source)
at java.util.regex.Matcher.<init>(Unknown Source)
at java.util.regex.Pattern.matcher(Unknown Source)
实在不明白。求高手帮助

客服端上传代码

SendMessage sendMms = sml.getSendMessage(new java.net.URL(
                    "http://127.0.0.1:8080/WebServiceProject/services/SendMessage"));
    for (int i = 0; i < mmsFileList.length; i++) {
                File f = new File(mmsFileList[i]);
                System.out.println("fname:"+f.getName());
                ((SendMessageBindingStub) sendMms)
                .addAttachment(new DataHandler(new FileDataSource(f)));
                 
            }

服务端获取代码:

try
        {
            //Attachments attachments = new Attachment();
            org.apache.axis.MessageContext msgCtx = org.apache.axis.MessageContext.getCurrentContext();
            Iterator attachments=msgCtx.getCurrentMessage().getAttachments();
            while(attachments.hasNext())
            {
                
                AttachmentPart ap=(AttachmentPart) attachments.next();
                System.out.println("name:"+ap.getAttachmentFile());
                System.out.println("type:"+ap.getContentType());
                System.out.println("size:"+ap.getSize());
                Pattern p = Pattern.compile(".*\\\\(\\w*).att");
                Matcher m = p.matcher(ap.getAttachmentFile());
                m.matches();
                MatchResult result=m.toMatchResult();
                String filename=result.group(1);
                File file = null;
                if (ap.getContentType().contains("text"))
                {
                    file = new File("C:\\" + filename + ".txt");    //文本附件
                }
                else if (ap.getContentType().contains("image"))
                {
                    System.out.println("image:");
                    file = new File("C:\\"+filename+".jpg");    //图片附件
                }
                else if (ap.getContentType().contains("application"))
                {
                    System.out.println("smil:");
                    file = new File("C:\\"+filename+".smi");    //图片附件
                }
                else
                {
                    System.out.println("other");
                    file = new File("C:\\"+filename+".dat");
                }
                    

                FileOutputStream fileOutputStream = new FileOutputStream(file);
                
                ap.getActivationDataHandler().writeTo(fileOutputStream);
                fileOutputStream.flush();
                fileOutputStream.close();
            }
            
        }
     
        catch (Exception e)
        {
            e.printStackTrace();
        }

实在对不起大家,误导大家了,这么嗝屁的问题,我想也不可能出嘛。

出现这问题有两个原因,

1:》我传的txt本来就是空的,后来无意中发觉了,实在对不起大家。

2:》

AttachmentPart ap=(AttachmentPart) attachments.next();
                System.out.println("name:"+ap.getAttachmentFile());
这样确实取不出来txt的名字,但能取出图片的名字,到底为什么不想深究, 取得文件名应该这样取:
ap.getDataHandler().getName()

over!!!!

sorry
