今天搭环境遇到几个错误，整理一下：
第一个：
Prometheus requires that all meters with the same name have the same set of tag keys. There is already an existing meter containing tag keys [method, status, uri]. The meter you are attempting to register has keys [exception, method, status, uri]
解决方法：
在application.properties中添加配置：
#zipkin启动报错无法访问的解决方法 management.metrics.web.server.auto-time-requests=false
第二个：
设置spring.sleuth.sampler.percentage=1无效。
解决方法：由于springcloud的版本太新，用spring.sleuth.sampler.probability=1即可。
