你搜索example里的demo，可以发现 service-registry/instance-status 这个接口的实现来自ServiceRegistryEndpoint类较低的版本里，可能没有这个类的实现

所以，我建议，这里摘除服务可以使用https://github.com/Netflix/eureka/wiki/Eureka-REST-operations

我们团队是使用这个接口来操作的

Take instance out of service	PUT /eureka/v2/apps/appID/instanceID/status?value=OUT_OF_SERVICE	HTTP Code: 200 on success 500 on failure
Move instance back into service (remove override)	DELETE /eureka/v2/apps/appID/instanceID/status?value=UP (The value=UP is optional, it is used as a suggestion for the fallback status due to removal of the override)	HTTP Code: 200 on success 500 on failure

重写一下那个enable和disable调用的controller，可能更通用一些.

    @RequestMapping(value = "status/{appName}", method = RequestMethod.POST)
    public ResultMap servStatus(@PathVariable String appName, String instanceId, String status){
        log.info("appName:{} instanceId:{} status:{} defaultZone:{}",
                new Object[] {appName, instanceId, status,defaultZone});

        //拼凑url
        String url= defaultZone;
        String outOfServiceUrl = defaultZone + "apps/%s/%s/status?value=OUT_OF_SERVICE";
        String upUrl = defaultZone + "apps/%s/%s/status?value=UP";

        if(status.equalsIgnoreCase("UP")) {
            //curl -v -X DELETE "127.0.0.1:9500/eureka/apps/CLIENT-A/192.168.1.101:client-a:7070/status?value=UP"
            upUrl = String.format(upUrl, appName, instanceId);
            HttpUtil.delete(upUrl, null, null, null, "UTF-8");
        } else if(status.equalsIgnoreCase("OUT_OF_SERVICE")) {
            outOfServiceUrl = String.format(outOfServiceUrl,appName,instanceId);
            //curl -v -X PUT "127.0.0.1:9500/eureka/apps/CLIENT-A/192.168.1.101:client-a:7070/status?value=OUT_OF_SERVICE"
            HttpUtil.put(outOfServiceUrl,null,null,null,"UTF-8");
        }

        return ResultMap.buildSuccess();
    }

EurekaClientController

倒不如用官方的rest API操作。

SpringCloud / eureka-admin
