Spring 端口中来自客户端的引导管理错误

Question

everyone!

I have a problem with Spring Boot Admin in Client side:

01-04-2021 23:02:37 [registrationTask1] ERROR o.s.s.s.TaskUtils$LoggingErrorHandler - Unexpected error occurred in scheduled task
java.lang.NoSuchMethodError: org.springframework.boot.actuate.autoconfigure.web.server.ManagementServerProperties.getBasePath()Ljava/lang/String;

my pom.xml:

<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-client</artifactId>
    <version>2.4.0</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
    <version>2.4.0</version>
</dependency>

my application.yaml:

spring.boot.admin:
  client:
    url: http://localhost:8080
    username: admin
    password: admin
    instance:
      metadata:
        user:
          name: ${spring.security.user.name}
          password: ${spring.security.user.password}
---
management:
  endpoints:
    web:
      exposure:
        include: httptrace,loggers,health,info,metrics

Admin-side works perfect. Client-side, when I write "url: http://localhost:8080" has error.

Does anybody know why?

Answer 1

May be your dependency versions of the admin server and admin client are different. And spring-boot-starter-actuator dependency may not be required.

Answer 2

This sounds similar to https://github.com/codecentric/spring-boot-admin/issues/1719

The getBasePath() method (being used by Spring Boot Admin Client 2.4) has been introduced with Spring Boot 2.4, are you sure that Spring Boot 2.4 is used at runtime?
