如何在特定的@FeignClient上禁用尤里卡查找(How to disable eureka lookup on specific @FeignClient)

 我有一个微服务，主要使用@FeignClient与其他微服务交谈。 使用Eureka的服务发现机制，这很美妙。 
 

 现在我迫切需要使用@FeignClient连接到外部系统，并仍然使用如下所示的配置执行负载平衡。 
 

 Feign client ： 
 

@FeignClient("externalServers")
public interface ExternalServersClient {
    @RequestMapping(method = RequestMethod.GET, value = "/someExternalUrl")
    ResponseEntity<Object> callExternalServer();
}

 

 application.yml ： 
 

externalServers:
  ribbon:
    listOfServers: server1:18201,server2:18201

 

 从我所经历的许多文档中，建议禁用eureka以允许从可用的listOfServers中获取负载均衡。 我确实遵循了这一点，并使用以下配置来禁用它。 
 

 application.yml ： 
 

ribbon:
  eureka:
    enabled: false

 

 这使我能够为假装客户端目标外部系统执行负载平衡，但所有其他需要使用服务发现的假装客户端都破了。 
 

 有没有办法为外部系统单独禁用eureka for feign客户端设置，但允许其为其他客户端正常运行？ 
 

 提前致谢！ 

I have a microservice that uses @FeignClient predominantly to talk to other micro-services. This works beautifuly using Eureka's service discovery mechanism.
 

Now I have a pressing need to use a @FeignClient to connect to an external system and still perform load balancing using configurations as shown below.
 

Feign client:
 

@FeignClient("externalServers")
public interface ExternalServersClient {
    @RequestMapping(method = RequestMethod.GET, value = "/someExternalUrl")
    ResponseEntity<Object> callExternalServer();
}

 

application.yml:
 

externalServers:
  ribbon:
    listOfServers: server1:18201,server2:18201

 

From many documentations that I have gone through, it is adviced to disable eureka to allow loadbalancing to be picked up from available listOfServers. I did follow that up and used following configuration to disable it. 
 

application.yml:
 

ribbon:
  eureka:
    enabled: false

 

This allowed me to perform loadbalancing for feign client targeting external systems but all other feign clients that need to use service discovery broke.
 

Is there any way to disable eureka for feign client setup for external system alone but allow it to function normally for other clients? 
 

Thanks in advance!

最满意答案

 是的，但您需要使用GraphicsDevice ， GraphicsEnvironment和GraphicsConfiguration API 
 

 Toolkit#getScreenSize就是这样，它返回屏幕的大小，但它不包括所有的OS元素，比如Dock，它占用了额外的空间 
 

 坐在码头上 
 

 所以，这是一堆库代码，旨在找到特定组件所在的GraphicsDevice ，或者，默认的GraphicsDevice ...库代码;） 
 

public static Rectangle getDefaultScreenBounds() {
    return getScreenBounds(null, true);
}

public static Rectangle getScreenBounds(Component comp, boolean acceptDefault) {
    Rectangle bounds = getScreenBounds(comp);
    if ((bounds == null || (bounds.x == 0 && bounds.y == 0 && bounds.width == 0 && bounds.height == 0)) && acceptDefault) {
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice gd = ge.getDefaultScreenDevice();
        bounds = gd.getDefaultConfiguration().getBounds();
    }
    return bounds;
}

public static Rectangle getScreenBounds(Component comp) {
    Rectangle bounds = new Rectangle(0, 0, 0, 0);
    GraphicsDevice gd = getGraphicsDevice(comp);

    if (gd != null) {
        GraphicsConfiguration gc = gd.getDefaultConfiguration();
        bounds = gc.getBounds();
    }
    return bounds;
}

public static GraphicsDevice getGraphicsDevice(Component comp) {
    GraphicsDevice device = null;
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice lstGDs[] = ge.getScreenDevices();
    List<GraphicsDevice> lstDevices = new ArrayList<>(lstGDs.length);
    if (comp != null && comp.isVisible()) {
        Rectangle parentBounds = comp.getBounds();
        /*
         * If the component is not a window, we need to find its location on the
         * screen...
         */
        if (!(comp instanceof Window)) {
            Point p = new Point(0, 0);
            SwingUtilities.convertPointToScreen(p, comp);
            parentBounds.setLocation(p);
        }

        for (GraphicsDevice gd : lstGDs) {
            GraphicsConfiguration gc = gd.getDefaultConfiguration();
            Rectangle screenBounds = gc.getBounds();
            if (screenBounds.intersects(parentBounds)) {
                lstDevices.add(gd);
            }
        }
        if (lstDevices.size() == 1) {
            device = lstDevices.get(0);
        } else {
            GraphicsDevice gdMost = null;
            float maxArea = 0;

            for (GraphicsDevice gd : lstDevices) {
                GraphicsConfiguration gc = gd.getDefaultConfiguration();
                Rectangle bounds = gc.getBounds();

                Rectangle2D intBounds = bounds.createIntersection(parentBounds);
                float perArea = (float) ((intBounds.getWidth() * intBounds.getHeight()) / (parentBounds.width * parentBounds.height));
                if (perArea > maxArea) {
                    maxArea = perArea;
                    gdMost = gd;
                }
            }
            if (gdMost != null) {
                device = gdMost;
            }
        }
    }

    return device;
}

 

 而且，这就是你如何使用它......

Yes, but you need to make use of the GraphicsDevice, GraphicsEnvironment and GraphicsConfiguration APIs
 

Toolkit#getScreenSize does just that, it returns the size of the screen, but it doesn't include all the OS elements, like the dock, which take up additional space
 

Sitting upon the dock
 

So, this is a bunch of library code, designed to find the GraphicsDevice a particular component resides on, or, the default GraphicsDevice ... library code ;)
 

public static Rectangle getDefaultScreenBounds() {
    return getScreenBounds(null, true);
}

public static Rectangle getScreenBounds(Component comp, boolean acceptDefault) {
    Rectangle bounds = getScreenBounds(comp);
    if ((bounds == null || (bounds.x == 0 && bounds.y == 0 && bounds.width == 0 && bounds.height == 0)) && acceptDefault) {
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice gd = ge.getDefaultScreenDevice();
        bounds = gd.getDefaultConfiguration().getBounds();
    }
    return bounds;
}

public static Rectangle getScreenBounds(Component comp) {
    Rectangle bounds = new Rectangle(0, 0, 0, 0);
    GraphicsDevice gd = getGraphicsDevice(comp);

    if (gd != null) {
        GraphicsConfiguration gc = gd.getDefaultConfiguration();
        bounds = gc.getBounds();
    }
    return bounds;
}

public static GraphicsDevice getGraphicsDevice(Component comp) {
    GraphicsDevice device = null;
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice lstGDs[] = ge.getScreenDevices();
    List<GraphicsDevice> lstDevices = new ArrayList<>(lstGDs.length);
    if (comp != null && comp.isVisible()) {
        Rectangle parentBounds = comp.getBounds();
        /*
         * If the component is not a window, we need to find its location on the
         * screen...
         */
        if (!(comp instanceof Window)) {
            Point p = new Point(0, 0);
            SwingUtilities.convertPointToScreen(p, comp);
            parentBounds.setLocation(p);
        }

        for (GraphicsDevice gd : lstGDs) {
            GraphicsConfiguration gc = gd.getDefaultConfiguration();
            Rectangle screenBounds = gc.getBounds();
            if (screenBounds.intersects(parentBounds)) {
                lstDevices.add(gd);
            }
        }
        if (lstDevices.size() == 1) {
            device = lstDevices.get(0);
        } else {
            GraphicsDevice gdMost = null;
            float maxArea = 0;

            for (GraphicsDevice gd : lstDevices) {
                GraphicsConfiguration gc = gd.getDefaultConfiguration();
                Rectangle bounds = gc.getBounds();

                Rectangle2D intBounds = bounds.createIntersection(parentBounds);
                float perArea = (float) ((intBounds.getWidth() * intBounds.getHeight()) / (parentBounds.width * parentBounds.height));
                if (perArea > maxArea) {
                    maxArea = perArea;
                    gdMost = gd;
                }
            }
            if (gdMost != null) {
                device = gdMost;
            }
        }
    }

    return device;
}
