我真的不了解你的问题，但至少我认为你在 runService 方法中遇到了问题：注意：在以“ ＆lt; - ”

开头的代码中添加了一些注释

    String stat = prop.getProperty("status"); <-- you read the property here
    if(stat.equals(status.FINISHED.toString()) || stat.equals(status.ONHOLD.toString()))
    {
        updateConfigfile(username+".properties","status",status.RUNNING.toString());
        do{
            i++;
            model.addAttribute("msg","inside loop"+" "+"Counter is:"+" "+i+" "+"status is =" +prop.getProperty("status"));  <-- status contains FINISHED or ONHOLD! It is the same as using stat variable.
        }while(prop.getProperty("status").equals(status.RUNNING.toString())); <--contains FINISHED or ONHOLD! so, always return false

    }else{
        model.addAttribute("msg","Service is already running");

    }

换句话说，如果您更改文件，则需要再次读取该文件，以便将更新的属性更新为属性对象。

希望这有帮助！

我的意思是这提到了我的上一条评论！

String stat = prop.getProperty("status");
            if(stat.equals(status.FINISHED.toString()) || stat.equals(status.ONHOLD.toString()))
            {
                updateConfigfile(username+".properties","status",status.RUNNING.toString());
                prop.setProperty("status",status.RUNNING.toString());
                i++;
                model.addAttribute("msg","inside loop"+" "+"Counter is:"+" "+i+" "+"status is =" +prop.getProperty("status"));
            }else{
                model.addAttribute("msg","Service is already running");

            }

config,properties file does not update in real time while running service via the browser
