检查下面的代码,这里我已经为每个事件类型添加了三条警报消息,但在此代码中source.onopen()[alert:readyState:1]和source.onerror()[alert:readyState:0]正常工作但在onmessage()的情况它没有被执行

       if(typeof(EventSource) !== "undefined") {
           var source = new EventSource('clinic/get');
           source.onopen = function(){
             alert('connection is opened.'+source.readyState);  
           };

           source.onerror = function(){
               alert('error: '+source.readyState);
           };

           source.onmessage = function(datalist){

               alert("message: "+datalist.data);
           };

        } else {
            document.getElementById("clinic-dtls").innerHTML = "Sorry, your browser does not support server-sent events...";
        }`

检查服务器端的以下代码

Random random = new Random();
        response.setContentType("text/event-stream");
        response.setCharacterEncoding("UTF-8");
        System.out.println("clinic/get got hit");

        try {
            Writer out = response.getWriter();
            out.write("data: welcome data"+random);
            out.flush();
            out.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

我正在使用STS(Spring工具套装),我想知道,当我在EventSource(源)对象上使用ctrl + space时,在选项中它只显示onopen()和onerror(),其中是onmessage(). …
