Question

SpringMVC 整合 kindeditor 我是新手 怎么也整不明白了

Answer 1

@RequestMapping(value = "/Kindeditor/uploadFile", method = RequestMethod.POST)

public void uploadFile(HttpServletRequest request, HttpServletResponse response) throws Exception {
PrintWriter writer = response.getWriter();
try {
// 文件保存目录路径
String savePath = request.getSession().getServletContext().getRealPath("/") + "upload" + File.separatorChar
+ "products" + File.separatorChar;
String saveUrl = request.getContextPath()+ File.separatorChar + "upload" + File.separatorChar
+ "products" + File.separatorChar;

// 定义允许上传的文件扩展名
HashMap<String, String> extMap = new HashMap<String, String>();
extMap.put("image", "gif,jpg,jpeg,png,bmp");

// 最大文件大小
long maxSize = 1000000;
response.setContentType("text/html; charset=UTF-8");

if (!ServletFileUpload.isMultipartContent(request)) {
writer.println(getError("请选择文件。"));
return;
}

File uploadDir = new File(savePath);
// 判断文件夹是否存在,如果不存在则创建文件夹
if (!uploadDir.exists()) {
uploadDir.mkdirs();
}

// 检查目录写权限
if (!uploadDir.canWrite()) {
writer.println(getError("上传目录没有写权限。"));
return;
}

String dirName = request.getParameter("dir");
if (dirName == null) {
dirName = "image";
}
if (!extMap.containsKey(dirName)) {

return;
}

MultipartHttpServletRequest mRequest = (MultipartHttpServletRequest) request;
Map<String, MultipartFile> fileMap = mRequest.getFileMap();
String fileName = null;
for (Iterator<Map.Entry<String, MultipartFile>> it = fileMap.entrySet().iterator(); it.hasNext();) {
Map.Entry<String, MultipartFile> entry = it.next();
MultipartFile mFile = entry.getValue();
fileName = mFile.getOriginalFilename();
// 检查文件大小
if (mFile.getSize() > maxSize) {
writer.println(getError("上传文件大小超过限制。"));
return;
}
String fileExt = fileName.substring(fileName.lastIndexOf(".")+1);
if (!Arrays.<String> asList(extMap.get(dirName).split(",")).contains(fileExt)) {
writer.println(getError("上传文件扩展名是不允许的扩展名。\n只允许" + extMap.get(dirName) + "格式。"));
return;
}
UUID uuid = UUID.randomUUID();
String path = savePath + uuid.toString() +"."+ fileExt;
saveUrl = saveUrl + uuid.toString() +"."+ fileExt;
BufferedOutputStream outputStream = new BufferedOutputStream(new FileOutputStream(path));
FileCopyUtils.copy(mFile.getInputStream(), outputStream);

JSONObject obj = new JSONObject();
obj.put("error", 0);
obj.put("url", saveUrl);
writer.println(obj.toString());

}

} catch (ServiceException serviceException) {
writer.println(getError(ApplicationContextUtil.getMessage(serviceException)));
return;
}
}

private String getError(String message) {
JSONObject obj = new JSONObject();
obj.put("error", 1);
obj.put("message", message);
return obj.toString();
}
