Spring cloud sleuth 没有 运行 Zipkin
Spring cloud sleuth did not run with Zipkin
首先我遇到了一个小问题 class brave.sampler.Sampler
无法导入此 class,仅在我添加此依赖项时导入
<dependency>
<groupId>io.zipkin.brave</groupId>
<artifactId>brave</artifactId>
<version>4.0.5</version>
</dependency>
我的大问题是,当我尝试使用 zipkin 进行干扰跟踪时,我添加了所需的依赖项,但是每当我启动应用程序时,它都会在启动时遇到异常。
这是堆栈跟踪。
