zipkin与redis依赖问题，其实是zipkin引入导致的死锁问题

引入zipkin导致启动报错

2020-07-18 09:13:06.390  INFO [,,,] 1088 [main] io.lettuce.core.EpollProvider            : Starting without optional epoll library
2020-07-18 09:13:06.413  INFO [,,,] 1088 [main] io.lettuce.core.KqueueProvider           : Starting with kqueue library

在配置文件加上spring.sleuth.redis.enabled=false

spring.zipkin.base-url=http://localhost:9411/
#关闭服务发现 否则springcloud会把zipkin的url当作服务名称
spring.zipkin.discovery-client-enabled=false
spring.zipkin.sender.type=web
#采样率
spring.sleuth.sampler.probability=1

spring.sleuth.redis.enabled=false
