        fetchRegistry: false
        serviceUrl:
          defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

this is the pom.xml:这是 pom.xml：

You can try it if you use the JDK >= 11:如果你使用 JDK >= 11 可以试试：

<dependency>
  <groupId>org.glassfish.jaxb</groupId>
  <artifactId>jaxb-runtime</artifactId>
</dependency>
