Spring Boot Admin Server 搭建過程中報錯記錄

今天嘗試項目裏面加入Spring Boot Admin，它是一個Web應用程序，用於管理和監視Spring Boot應用程序。它分爲Server端和Client端，每個應用程序都被視爲客戶端並註冊到管理服務器。實現的原理則是基於Spring Boot Actuator提供的端點。

搭建admin-server

1.pom文件引入相關依賴

<!-- 添加admin-server、admin-server-ui依賴 -->
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-server</artifactId>
    <version>2.0.1</version>
</dependency>
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-server-ui</artifactId>
    <version>2.0.1</version>
</dependency>

2.啓動類添加註解@EnableAdminServer

3.啓動服務出現下面錯誤信息

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method reactor.retry.Retry.retryMax(I)Lreactor/retry/Retry; but it does not exist. Its class, reactor.retry.Retry, is available from the following locations:

    jar:file:/D:/mymaven/repository/io/projectreactor/addons/reactor-extra/3.2.0.RELEASE/reactor-extra-3.2.0.RELEASE.jar!/reactor/retry/Retry.class

It was loaded from the following location:

    file:/D:/mymaven/repository/io/projectreactor/addons/reactor-extra/3.2.0.RELEASE/reactor-extra-3.2.0.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of reactor.retry.Retry

項目沒能啓動就報錯，查看錯誤信息。大概意思：“嘗試調用方法reator . retry.retry.retrymax (I)Lreactor/retry/ retry;但它並不存在。它的類,reactor.retry。重試，可在以下地點下載:下面就是兩個下載地址”。上網查找相關報錯信息發現根本原因就是pom.xml文件中版本依賴有問題。查看我spring boot版本信息：2.1.0.RELEASE，於是將spring-boot-admin-server也升級版本

<dependency>
   <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-server</artifactId>
    <version>2.1.0</version>
</dependency>
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-server-ui</artifactId>
    <version>2.1.0</version>
</dependency>

再次啓動成功，特此記錄！
