No ‘Access-Control-Allow-Origin‘ header is present on the requested resource. Origin

一、服务器端解决

    @ResponseBody
    @GetMapping("/userSource.json")
    public Object userSource(String search,HttpServletResponse response) {
        System.out.println(search);
        response.setHeader("Access-Control-Allow-Origin", "*");
        return getUserSourceService().findAll();
    }
