jspsmart 下载文件不支持中文 升级使其另存为时显示中文,但打开时还是乱码(已修改正常)

上网看了一下才知道jspsmart不支持中文~~~~,晕~~~~要升级它

 

1.用jad 反编译 得到java文件

     这里也可能会遇到难题~~~

    我的机子还装了C#的VS,所以可能反编译时用的是vs的编译器.如果把这样反编译得到的.java文件放在eclipse下是不能编译成.class的,所以要自己一个个地新建一个类,然后复制内容进去~~~~~

 

 

2.添加方法

SmartUpload.java中加入

 

1. //添加转换文件名字符串的方法
2.     public static String toUtf8String(String s) {
3.         StringBuffer sb = new StringBuffer();
4.         for (int i = 0; i < s.length(); i++) {
5.             char c = s.charAt(i);
6.             if (c >= 0 && c <= 255) {
7.                 sb.append(c);
8.             } else {
9.                 byte[] b;
10.                 try {
11.                     b = Character.toString(c).getBytes("utf-8");
12.                 } catch (Exception ex) {
13.                     System.out.println(ex);
14.                     b = new byte[0];
15.                 }
16.                 for (int j = 0; j < b.length; j++) {
17.                     int k = b[j];
18.                     if (k < 0)
19.                         k += 256;
20.                     sb.append("%" + Integer.toHexString(k).toUpperCase());
21.                 }
22.             }
23.         }
24.         return sb.toString();
25.     }

修改downloadFile方法

 

1. public void downloadFile(String s, String s1, String s2, int i)
2.         throws ServletException, IOException, SmartUploadException
3.     {
4.         if(s == null)
5.             throw new IllegalArgumentException("File '" + s + "' not found (1040).");
6.         if(s.equals(""))
7.             throw new IllegalArgumentException("File '" + s + "' not found (1040).");
8.         if(!isVirtual(s) && m_denyPhysicalPath)
9.             throw new SecurityException("Physical path is denied (1035).");
10.         if(isVirtual(s))
11.             s = m_application.getRealPath(s);
12.         java.io.File file = new java.io.File(s);
13.         FileInputStream fileinputstream = new FileInputStream(file);
14.         long l = file.length();
15.         boolean flag = false;
16.         int k = 0;
17.         byte abyte0[] = new byte[i];
18.         if(s1 == null)
19.             m_response.setContentType("application/x-msdownload");
20.         else
21.         if(s1.length() == 0)
22.             m_response.setContentType("application/x-msdownload");
23.         else
24.             m_response.setContentType(s1);
25.         m_response.setContentLength((int)l);
26.         m_contentDisposition = m_contentDisposition != null ? m_contentDisposition : "attachment;";
27.         if(s2 == null)
28.             m_response.setHeader("Content-Disposition", m_contentDisposition + " filename=" + toUtf8String(getFileName(s)));
29.       //转换文件名
30.         else
31.         if(s2.length() == 0)
32.             m_response.setHeader("Content-Disposition", m_contentDisposition);
33.         else
34.             m_response.setHeader("Content-Disposition", m_contentDisposition + " filename=" + toUtf8String(s2));
35.         //转换文件名
36.         while((long)k < l) 
37.         {
38.             int j = fileinputstream.read(abyte0, 0, i);
39.             k += j;
40.             m_response.getOutputStream().write(abyte0, 0, j);
41.         }
42.         fileinputstream.close();
43.     }

这里只是对文件名的字符进行更改.

 

3.用eclipse打包

 

打包时去掉.classpath ; .project前的勾~~~~

 

 

 4.打开后不乱码的修改方法~~~

SmartUpload.java

 

public void downloadFile(String s, String s1, String s2, int i)
        throws ServletException, IOException, SmartUploadException

      //转换文件名
        else
        if(s2.length() == 0)
            m_response.setHeader("Content-Disposition", m_contentDisposition);
        else

        //转换文件名
        while((long)k < l)
        {
