Answer 1

Brixton.SR5 是 from 2016 and doesn't support Spring Boot 2 since it was released in 2018。如果它与 Spring 低于 2.1.1 的引导版本一起工作，那是偶然的。

您需要将 Spring Cloud 升级到最新版本，例如Finchley SR2.

Answer 2

Brixton builds on Spring Boot 1.3.x

Finchley builds and works with Spring Boot 2.0.x, and is not expected to work with Spring Boot 1.5.x.

用芬奇利替换布里克斯顿。在您的 pom 中添加以下依赖项：

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