异步回调

调用方在调用本接口时，会在接口地址后跟回调地址，然后提供方立刻返回一个结果，并启动一个线程执行业务逻辑，执行完后请求回调地址，实现异步回调，这里只给出提供方demo：

    @ApiOperation(value = "自动同步权限")
    @RequestMapping(value = "/auto_synchronize_permission", method = RequestMethod.POST)
    @ResponseBody
    public TestResult autoSynchronize(HttpServletRequest httpServletRequest){
        String callback = httpServletRequest.getParameter("callback");//回调url
        new Thread(){
            public void run(){
                TestResult testResult = testPermissionCategoryService.autoSynchronize();//具体实现
                JSONObject request =new JSONObject();
                request.put("result", testResult);
                try {
                    String res = HttpClientUtil.doPostJson(callback, request.toJSONString(), null);
                    log.info(res);
                } catch (Exception e) {
                    log.info(e.getMessage(), e);
                }
            }
        }.start();
        return new TestResult(BaseMessage.SUCCESS);
    }
