我得到了一个“白标错误页面"使用 Eureka 服务器时 [英] I got a "Whitelabel Error Page" when using Eureka server
问题描述
我使用 SPRING INITIALIZR 创建了一个 Spring Cloud 项目.我的项目结构如下:在此处输入图片描述
I created a spring cloud project using SPRING INITIALIZR. My project structure is as below: enter image description here
演示应用程序:
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
application.properties:
application.properties:
server.port=8888
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.instance.hostname=localhost
eureka.client.service-url.defaultZone=localhost:8888/eureka
spring.application.name=appName

但是当我访问localhost:8888时,出现如下错误:
But when I visit localhost:8888, the following error occurs:
白标错误页面此应用程序没有针对/error 的显式映射,因此您将其视为后备.
Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.
2018 年 12 月 2 日星期日 11:23:36 CST出现意外错误(类型=未找到,状态=404).没有可用的消息
Sun Dec 02 11:23:36 CST 2018 There was an unexpected error (type=Not Found, status=404). No message available
我不知道为什么会这样.我该如何解决?
I don't konw why this happens.How can I solve this?
推荐答案
至少最新版本的 SpringBoot 和 Cloud 需要这些配置才能让 Eureka UI 出现:
at-least the latest version of SpringBoot and Cloud requires these configs for Eureka UI to come up:
#in application.yml
spring:
freemarker:
template-loader-path: classpath:/templates/
prefer-file-system-access: false
或
#in application.properties
spring.freemarker.template-loader-path= classpath:/templates/
spring.freemarker.prefer-file-system-access= false
