如何遍历每个数据对象的ajax请求并为每个文件提取文件名，消息？有人可以帮忙吗？
将List解析回客户端的服务器端控制器：
@RequestMapping(value = { "/fileUpload" }, method = RequestMethod.POST)
@ResponseBody
public List<FileUpload> uploadFile( @RequestParam("number") String number, @RequestParam("files[]") MultipartFile[] files, MultipartHttpServletRequest req, HttpServletResponse res)
{
WebUserSession session = (WebUserSession) req.getSession().getAttribute("webUserSession");
String windowsUsername = session.getUsername();
List<FileUpload> fileList = itsmService.uploadFile(files, windowsUsername, number);
int countTrue = 0;
int countFalse = 0;
for (FileUpload loopFile : fileList)
{
if (loopFile.getSuccess())
{
countTrue++;
}
else
{
countFalse++;
}
}
return fileList;
}
}
ajax请求的一部分客户端数据对象：
success : function(data) {
FileUploadVisible(true);
console.log(data);
}

你可以这样做：
[{"name":"toto.txt", "message":"bla", "success":true},{"name":"titi.txt", "message":"blabla", "success":true}]
或者如果您只想显示成功上传的文件：
success:function(fileList) {
fileList.forEach(function(file){
console.log("File name:" + file.name + ", msg:" + file.message + ", success: " + file.success);
})
}
