spring boot 支持通过 ajax 跨域请求的设置

如题

@RequestMapping("/api")
public Object getResponse(BaseRequest baseRequest, HttpServletRequest request, HttpServletResponse response) {
    //允许跨域访问的代码，开发时仅为了配合前端测试
    if (ApgConfig.isDev == YesOrNoEnum.yes.getIndex()) {
        response.setHeader("Access-Control-Allow-Origin", "*");
    }

    return ApgAdapterService.getApiResponse(baseRequest, request);
}

否则会报错：

Failed to load http://doman/api: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
