springcloud finchley爬坑记
springcloud 发布了finchley Release版，只兼容springboot 2.x,项目升级到新版，遇到了各种坑，在此记录。版本构建使用gradle,如果是maven对应过去就可以了。
1 eureka client引入发生变化，新版多了netflix
旧版：compile "org.springframework.cloud:spring-cloud-starter-eureka-client"
新版：compile "org.springframework.cloud:spring-cloud-starter-netflix-eureka-client"2 feign引入发生变化,多了open
旧版:compile('org.springframework.cloud:spring-cloud-starter-feign')
新版:compile('org.springframework.cloud:spring-cloud-starter-openfeign')3 hystrix, hystrix-dashboard引入发生变化，多了netflix
旧版：
compile('org.springframework.cloud:spring-cloud-starter-hystrix')
compile('org.springframework.cloud:spring-cloud-starter-hystrix-dashboard')
新版：
compile('org.springframework.cloud:spring-cloud-starter-netflix-hystrix')
compile('org.springframework.cloud:spring-cloud-starter-netflix-hystrix-dashboard')4 context.path配置发生变化，多了servlet
旧版:server.context-path: xxxx
新版:server.servlet.context-path: xxxx5 zipkin配置发生变化（服务端）
据说是spring建议使用jar包直接运行zipkin-server
从zipkin官网下载jar包运行，[zipkin官网](https://zipkin.io/)，如果使用rabbitmq或kafka做异步收集，需要配置环境变量，见下面地址http://www.mamicode.com/info-detail-2292005.html.本人在winows下cgywin下亲测不好使，后来去github看了下zipkin源码，找到了解决办法。github源码地址：https://github.com/openzipkin/zipkin。zipkin-server,resources下的配置文件拷贝一份放到jar包同级目录下，配置rabbitmq的信息搞定。
配置文件见下面，修改其中的rabbitmq.addresses,rabbitmq.username,rabbitmq.password,如果用的kafka，修改对应的就好了。

直接引入compile "org.springframework.cloud:spring-cloud-starter-zipkin"就够了。
配置文件配置如下：
spring:
sleuth:
web:
client:
enabled: true
sampler:
probability: 1.0 # 将采样比例设置为 1.0，也就是全部都需要。默认是 0.1
zipkin:
base-url: http://localhost:9411/ # 指定了 Zipkin 服务器的地址7 springsecurity httpbasic验证发生变化eureka server验证发生改一下。eureka server修改如下：
#springboot2以上不支持
#security:
# basic:
# enabled: true
# user:
# name: zqw
# password: zqw
在main方法类或自定义一个带@Configuration的类加入如下内容，将csrf disabled掉，自定义验证的用户名密码,这样eureka client 就可以像旧版一样 http://[user]:[password]@xxxx与server建立连接了
@EnableWebSecurity
static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.passwordEncoder(NoOpPasswordEncoder.getInstance())
.withUser("zqw").password("zqw")
.authorities("ADMIN");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf()
.disable()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.httpBasic();
}
}8 bus总线配置发生变化
现在要将actuator endpoint 手动放开一下
management.endpoints.web.exposure.include: bus-refresh
如果这样配置management.endpoints.web.exposure.include=* 在yml文件是行不通的，会报错，加上双引号或使用properties文件。
手动刷新的地址也发生了变化， POST方式，http://xxxxxx/actuator/bus-refresh
9 tubine配置，由于actuator发生变化，配置做相应修改，见这个文章
https://blog.csdn.net/ifrozen/article/details/80019143
上面文章介绍了基本的turbine配置方式，注意turbine服务端配置，
其中instanceUrlSuffix:
default: actuator/hystrix.stream
因为springboot2.x actuator 默认需要在路径上带上/actuator，这里定义了
后缀就可以用了
turbine:
app-config: consumer-client
cluster-name-expression: "'default'"
# cluster-name-expression: metadata['cluster'] //不好用不知道为什么
combine-host-port: true
# aggregator:
# cluster-config: MAIN
instanceUrlSuffix:
default: actuator/hystrix.stream
上面解决了基本配置问题，还有一个问题就是当自定义了server.context-path,turbine
又用不了了，可以用下面这样的方式解决。其中自定义management.server.port,将management.server.servlet.context-path 置为 /,这样turbine可以用了
management:
endpoints:
web:
exposure:
include: "*"
cors:
allowed-methods: "*"
allowed-origins: "*"
server:
port: 5101
servlet:
context-path: /10 datasource 自动配置出现循环引用错误
Description:
The dependencies of some of the beans in the application context form a cycle:
servletEndpointRegistrar defined in class path resource [org/springframework/boot/actuate/autoconfigure/endpoint/web/ServletEndpointManagementContextConfiguration.class]
↓
healthEndpoint defined in class path resource [org/springframework/boot/actuate/autoconfigure/health/HealthEndpointConfiguration.class]
↓
dbHealthIndicator defined in class path resource [org/springframework/boot/actuate/autoconfigure/jdbc/DataSourceHealthIndicatorAutoConfiguration.class]
┌─────┐
| scopedTarget.dataSource defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]
↑ ↓
| org.springframework.boot.autoconfigure.jdbc.DataSourceInitializerInvoker
找了好久终于找到解决方式配置文件添加spring.cloud.refresh.refreshable: none
