java - 创建还包含 Sleuth 依赖项的 Spring Boot 管理服务器

Question

我正在开发 Spring Boot 管理服务器。当我添加 Sleuth 依赖项(用于跟踪分布式架构中的请求和响应)时，我在启动时遇到异常。当我在 POM 中注释掉 Sleuth 依赖项时，应用程序启动得很好。

我添加了 spring-cloud-starter-zuul 依赖项并启动了应用程序

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zuul</artifactId>
</dependency>
