如何在Spring MVC Controller获取呼叫中提取IP地址？

解决方法是

@RequestMapping(value = "processing", method = RequestMethod.GET)public @ResponseBody ProcessResponse processData(@RequestParam("workflow") final String workflow,    @RequestParam("conf") final String value, @RequestParam("dc") final String dc, HttpServletRequest request) {        System.out.println(workflow);        System.out.println(value);        System.out.println(dc);        System.out.println(request.getRemoteAddr());        // some other pre    }

添加

HttpServletRequest request
