Question

求助：用spring MultipartFile实现上传，中文乱码怎么处理？在线等~~

@RequestMapping("/uploadPage")
@ResponseBody
public String uploadPage(Long id,@RequestParam("userfile") CommonsMultipartFile mFile){
long maxSize = 1000000;
String message = null;
if (!mFile.isEmpty()) {
NewActivity activity = NewActivity.findNewActivity(id);
String fileName = mFile.getOriginalFilename();
if(mFile.getSize()>maxSize){
message = "上传文件大小超过限制。";
return "{\"failure\":\"" + message + "\"}";
}
File file = new File(ACTIVITY_PAGE+fileName);
activity.setLinkAddress(fileName.replace(".jsp", ".html"));
activity.merge();
try {
mFile.getFileItem().write(file); //将上传的文件写入新建的文件中
} catch (Exception e) {
e.printStackTrace();
}
}
return "true";
}
上面是上传的java代码，页面是extjs，上传的文件是jsp，上传完以后文件中的中文都变成乱码了。怎么处理，在线等~~~

Answer 1

uploadPage 接受参数加个 HttpServletRequest 方法最上面写一下。
if (request.getCharacterEncoding() == null) {
request.setCharacterEncoding("UTF-8");//你的编码格式
}
