Answer 1

Brixton.SR5是從2016年開始的 ，自2018年發布以來不支持Spring Boot 2。 如果它適用於2.1.1以下的Spring Boot版本，那是偶然的。

您需要將Spring Cloud升級到最新版本，例如Finchley SR2 。

Answer 2

Brixton建立在Spring Boot 1.3.x之上

Finchley構建並與Spring Boot 2.0.x一起使用，並且不能與Spring Boot 1.5.x一起使用。

用Finchley替換Brixton。 在pom中添加以下依賴項：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-dependencies</artifactId>
    <version>Finchley.RELEASE</version>
    <type>pom</type>
</dependency>
