Spring Boot Admin客戶端狀態為關閉

Question

我有一個SpringAdminServer（1.5.0），一個EurekaServer和一個EurekaClient。

SpringAdminServer使用@EnableDiscoveryClient方式進行托管。 我可以看到SpringAdminServer和EurekaClient都正常注冊到EurekaServer。 但是，SpringAdminServer上顯示的EurekaClient的狀態始終為“ DOWN”。（SpringAdminServer顯示404錯誤，要求EurekaClient的/ info或/ metric路徑...）

我嘗試了另一種方式，將spring-boot-admin-starter-client包含在客戶端的POM中，這將使客戶端在SpringAdminServer上的狀態變為UP，因此未發現請求/ info或/ metric路徑的錯誤...

有人知道發生了什么嗎？ 謝謝。

這是我客戶的POM的內容：

Answer 1

加

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>

到POM就能解決問題。
