Can I assign the same URL to more than one controller?

I'm trying to use AJAX

$.ajax({
    url : urlN, // <<- "/log"
    type: "post",
    success : function(json) {
        console.log(json);
        document.getElementById('content').innerHTML = json;
    }

setInterval(refreshDiv, 5000);

To update, at each 'X' times, only one part of an HTML page ( <div> ). The problem is that I could not get the contents of my file, because my controller returned the name of my view, which resulted in this:

That is, my problem was reversed ..

Mycontroller:

@RequestMapping(value="/log", method = RequestMethod.POST)
    @ResponseBody
         //String  - View
    public Log jsonLogContent(@Valid Log log, BindingResult bindingResult, Map<String, Object> model) {
        if (log.getInitLine() == 0 && log.getFinalLine() == 0) {
            try {
                fileNumberLines(log);
                log.setPathFile(logsDir + "/" + log.getFilename());
                log.setContent(getLogContentByRange(0, log.getInitLine(), log.getFinalLine(), log.getPathFile()));
            } catch (IOException e) {
                logger.error(e.getMessage());
            }
        } else {
            log.setContent(getLogContentByRange(0, log.getInitLine(), log.getFinalLine(), logsDir + "/" + log.getFilename()));
        }

        model.put("path", logsDir);
        model.put("log", log);
        model.put("currentPage", "logs");
        model.put("root", root);
       //return "log"; - View
        return log;    // Obj
    }

My question:

Is there any way around this? Making it possible  two URL's for the same controller? Or a way for the view to load  first and then the object?
