启用Netflix Zuul会导致instancealready存在异常

Question

Pom文件-

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zuul</artifactId>
        <version>1.4.0.RELEASE</version>
    </dependency>

Application.properties-

spring.application.name=portal-app
spring.jmx.default-domain=portal-jmx
#zuul properties
zuul.routes.resource.url=http://clm-aus-t1gkxh:8095/api/v1/
ribbon.eureka.enabled=false

SpringBootApplication类-

package com.***.**.portal;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
import org.springframework.boot.web.servlet.ErrorPage;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.RestController;

import com.**.**.portal.filters.PreRequestFilter;


@EnableZuulProxy
@RestController
@ComponentScan({"com.***.common.portal", "com.***.common.portal.controllers", "com.***.dem",
        "com.***.costportal.controllers", "com.***.cost.portal"})
@SpringBootApplication
public class CostPortalApplication extends SpringBootServletInitializer {

    @Bean
    public EmbeddedServletContainerCustomizer containerCustomizer() {

        return (container -> {
            ErrorPage error400Page = new ErrorPage(HttpStatus.BAD_REQUEST, "/error/400.html");
            ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/error/401.html");
            ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/error/404.html");
            ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error/500.html");

            container.addErrorPages(error400Page, error401Page, error404Page, error500Page);
        });
    }

    public static void main(String[] args) {
        SpringApplication.run(CostPortalApplication.class, args);
    }

    @Bean
    public PreRequestFilter preRequestFilter() {
        return new PreRequestFilter();
    }
}

上面的代码启用zuul路由器进行资源服务，并启用了很少的在同一服务上运行的其余端。

在本地环境（例如运行mvn spring-boot：run）中，此方案可以正常工作。但是，如果我将战争部署到Elastic Bean堆栈中的Tomcat 8中，它将因instancealreadyexisting异常而失败。
