## README

# springcloud

#### 介绍
分布式学习！
###
Robbin 测试负载均衡 轮询
访问 localhost/comsumer/dept/list
查看返回结果内返回的是哪个数据库的.应该是每个数据库都返回一次
# Hystrix
测试熔断
localhost/comsumer/dept/get/255 数据库不存在的数据
## 服务降级
运行某个provider,然后关闭,再访问某个连接就会出现下面的信息
{"deptno":1,"dname":"该ID：1没有没有对应的信息,Consumer客户端提供的降级信息,
此刻服务Provider已经关闭","db_source":"no this database in MySQL"}
# 服务监控
http://localhost:8001/hystrix.stream

# Springcloud config

http://config-3344.com:3344/application-xxx.yml(不存在的配置)
spring:

#客户端读取数
bootstrap.yml里面的profile值是什么，决定从github上读取什么
http://client-config.com:8201/config
dev默认在github上对应的端口就是8201
