Spring Controller很容易将String type Object发送到客户端ajax/angularjs,但无法发送任何其他对象。
我使用的是SpringMVC4.1。4、Maven、tiles、mysql、hibernate、jsp、ajax技术在我的项目中。请帮我解决这个问题。

这个答案也很有帮助,所以我要问你一个问题

我有一个ASP.NET Core1.0Web API应用程序,并试图弄清楚如果我的控制器调用的函数出错,如何将异常消息传递给客户端。 我确实看到了一些使用的文档,但是为了使用它,我必须安装compat shim。在Core1.0中有没有一种新的方法来做这些事情? 这是我一直在尝试的垫片,但它不起作用: 当抛出时,我查看客户端,在内容中找不到我正在发送的消息。
使用worker来做服务器,没有用GatewayWorker,如何实现向指定用户推送消息? <?php use WorkermanWorker; require_once __DIR__ . '/Workerman/Autoloader.php'; // 初始化一个worker容器,监听1234端口 $worker = new Worker('websocket://workerman.net:1
