系统对接要接入别的系统，需要自动登录进去

设计一个中转页：自动JavaScript触发表单提交即可

    /**
     * 跳转Datastudio
     * @param request request
     * @return ModelAndView
     */
    @RequestMapping("gotoDatastudio")
    public ModelAndView gotoDatastudio(HttpServletRequest request) {
        ModelAndView view = new ModelAndView("bdm/gotoDatastudio");
        String workflowUrl = configRemoteService.getByKey("big.data.studio.login.url", "http://datastudio.chinamuseum.cn:31479/login");
        workflowUrl +="?login_url="+request.getParameter("login_url");
        String username = configRemoteService.getByKey("big.data.studio.login.username", "admin");
        String password = configRemoteService.getByKey("big.data.studio.login.password", "admin");
        view.addObject("workflowUrl", workflowUrl);
        view.addObject("username", username);
        view.addObject("password", password);
        return view;
    }
