采用jspsmartupload上传文件时，如果文件名含有中文，在服务器端取得文件名是会出现乱码。如果表单项中填写了中文，一样会有乱码问题。看了下jspsmartupload的源码，改了两个地方，现在可以没有乱码问题了。
第一个地方，修改类SmartUpload中的upload()方法
Java代码
public void upload()
throws SmartUploadException, IOException, ServletException
{
int totalRead = 0;
int readBytes = 0;
long totalFileSize = 0L;
boolean found = false;
String dataHeader = new String();
String fieldName = new String();
String fileName = new String();
String fileExt = new String();
String filePathName = new String();
String contentType = new String();
String contentDisp = new String();
String typeMIME = new String();
String subTypeMIME = new String();
boolean isFile = false;
m_totalBytes = m_request.getContentLength();
m_binArray = new byte[m_totalBytes];
for(; totalRead < m_totalBytes; totalRead += readBytes)
try
{
m_request.getInputStream();
readBytes = m_request.getInputStream().read(m_binArray, totalRead, m_totalBytes - totalRead);
}
catch(Exception e)
{
throw new SmartUploadException("Unable to upload.");
}
for(; !found && m_currentIndex < m_totalBytes; m_currentIndex++)
if(m_binArray[m_currentIndex] == 13)
found = true;
else
m_boundary = m_boundary + (char)m_binArray[m_currentIndex];
if(m_currentIndex == 1)
return;
m_currentIndex++;
do
{
if(m_currentIndex >= m_totalBytes)
break;
dataHeader = getDataHeader();
m_currentIndex = m_currentIndex + 2;
isFile = dataHeader.indexOf("filename") > 0;
fieldName = getDataFieldValue(dataHeader, "name");
if(isFile)
{
filePathName = getDataFieldValue(dataHeader, "filename");
fileName = getFileName(filePathName);
fileExt = getFileExt(fileName);
contentType = getContentType(dataHeader);
contentDisp = getContentDisp(dataHeader);
typeMIME = getTypeMIME(contentType);
subTypeMIME = getSubTypeMIME(contentType);
}
getDataSection();
if(isFile && fileName.length() > 0)
{
if(m_deniedFilesList.contains(fileExt))
throw new SecurityException("The extension of the file is denied to be uploaded (1015).");
if(!m_allowedFilesList.isEmpty() && !m_allowedFilesList.contains(fileExt))
throw new SecurityException("The extension of the file is not allowed to be uploaded (1010).");
if(m_maxFileSize > (long)0 && (long)((m_endData - m_startData) + 1) > m_maxFileSize)
throw new SecurityException(String.valueOf((new StringBuffer("Size exceeded for this file : ")).append(fileName).append(" (1105).")));
totalFileSize += (m_endData - m_startData) + 1;
if(m_totalMaxFileSize > (long)0 && totalFileSize > m_totalMaxFileSize)
throw new SecurityException("Total File Size exceeded (1110).");
}
if(isFile)
{
com.jspsmart.upload.File newFile = new com.jspsmart.upload.File();
newFile.setParent(this);
newFile.setFieldName(fieldName);
newFile.setFileName(fileName);
newFile.setFileExt(fileExt);
newFile.setFilePathName(filePathName);
newFile.setIsMissing(filePathName.length() == 0);
newFile.setContentType(contentType);
newFile.setContentDisp(contentDisp);
newFile.setTypeMIME(typeMIME);
newFile.setSubTypeMIME(subTypeMIME);
if(contentType.indexOf("application/x-macbinary") > 0)
m_startData = m_startData + 128;
newFile.setSize((m_endData - m_startData) + 1);
newFile.setStartData(m_startData);
newFile.setEndData(m_endData);
m_files.addFile(newFile);
} else
{
/**
* 原来的代码
* String value = new String(m_binArray, m_startData, (m_endData - m_startData) + 1);
*/
/**
* 2009-9-17 修改 ，解决取得request的参数的中文编码问题
*/
String value = new String(m_binArray, m_startData, (m_endData - m_startData) + 1, "utf-8");
m_formRequest.putParameter(fieldName, value);
}
if((char)m_binArray[m_currentIndex + 1] == '-')
break;
m_currentIndex = m_currentIndex + 2;
} while(true);
}
第二个地方，修改类SmartUpload中的getDataHeader()方法
Java代码
private String getDataHeader()
{
int start = m_currentIndex;
int end = 0;
int len = 0;
boolean found = false;
while(!found)
if(m_binArray[m_currentIndex] == 13 && m_binArray[m_currentIndex + 2] == 13)
{
found = true;
end = m_currentIndex - 1;
m_currentIndex = m_currentIndex + 2;
} else
{
m_currentIndex++;
}
//原始代码
//String dataHeader = new String(m_binArray, start, (end - start) + 1);
/**
* 2008-9-17 解决文件名的中文乱码问题
*/
String dataHeader = null;
try {
dataHeader = new String(m_binArray, start, (end - start) + 1,"utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return dataHeader;
}
