Spring Eureka App doesn't show dashboard

问题

There is a Eureka Server application:

@EnableEurekaServer
@SpringBootApplication
public class RegistrationModulesServiceApplication {

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

With applicaton.yml config (be default):

eureka:
  instance:
    hostname: localhost
  client: 
    registerWithEureka: false
    fetchRegistry: false

server:
  port: 1111  

On the first run - I saw dashboard with statuses. Like in documentation:

Then - after restart I can see only xml response:

Why?

No error in log.

回答1:

I encounter the exact same issue, after long time investigation, just: delete the folder "templates" and "static" from /src/main/resources

回答2:

For me, the issue was that I had an empty folder, src/main/resources/templates. When this folder exists, FreeMarkerView cannot see the embedded templates contained in spring-cloud-netflix-eureka-server. I don't remember where this folder originated but I suspect it is in the online sample.

Try using this spring boot / cloud versions:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.1.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent> 

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Dalston.BUILD-SNAPSHOT</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

and maybe setting environment

eureka:
  environment: dev

There is a full example in this github project

It was also not working for me, then I made some changes in my pom.xml and then it worked

May this will help

--Edit-- my application.yml file looks like:

server:
  port: 8010

eureka:  
  instance:
    hostname: localhost    
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
