我使用javascript客户端库使用云端点服务.我正在尝试从端点服务获取数据,但每次我要求我获得由端点api猜测的不同数据.有没有办法让端点服务不缓存数据？这是我通过点击https://application.appspot.com/_ah/api/jobssyste/v1/servicetogetdata?accountNumber=8661234567得到的示例回复

在这里,我得到连续请求的回复

但firstResponse数据是我在DataStore中的数据.无法找到此缓存数据的来源.即使我试着提到不要使用端点方法缓存.@ApiMethodCacheControl(非缓存=真,MAXAGE = 0).快速准确的解决方案是适合的.谢谢.

我试图让一个按钮调用另一个类中的方法来更新某些东西的颜色,但它没有按照我的预期运行.问题是颜色改变一次但从未改变过.

这是发生变化的文件:

public class Status
{
    //initial conditions
    Color pedLightColor = Color.RED;
    Color warnLightsColor = Color.GREEN;
    Boolean GatesUp= true;
    Color drawbridgeColor = Color.green;    
    public Status()
    {       
    }

    public Color getPedestrianStatus()
    {
       return pedLightColor;
    }

    public void setPedestrianColor(Color c)
    {
        if(c.equals(Color.RED))
        {
           pedLightColor=Color.green;
           System.out.println("Pedestrian Light color changed to " + pedLightColor);
        }
        else
        {
               pedLightColor=Color.red;
               System.out.println("Pedestrian Light color changed to " + pedLightColor);
        }
    }
}

它被称为如下:

pedButton.addActionListener(new ActionListener() 
{
        @Override
        public void actionPerformed(ActionEvent event) 
        {
           System.out.println("Control Unit/Pedestrian Button Clicked");
           Status …
