项目中加入统一配置,服务发现,api路由等云服务功能。这里采用spring cloud。
修改/huip/pom.xml
在这里,把各个项目都要用到的配置模块,eureka模块包含进来。也可以各个子项目中分别包含。

服务发现(eureka)
创建项目huip-eureka
创建项目
pom.xml
这是eureka服务提供项目,需要包含spring-cloud-starter-netflix-eureka-server模块。spring cloud Finchley之后才有这个模块。

在src/main/resources中新建文件bootstrap.yml。内容如下:
server:
port: 8761
spring:
application:
name: huip-eureka-server
cloud:
config:
uri: ${CONFIG_SERVER_URL:http://localhost:8886} # 统一配置服务地址
eureka:
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://${eureka.host:localhost}:${server.port:8761}/eureka
server:
waitTimeInMsWhenSyncEmpty: 0
enableSelfPreservation: false
统一配置服务(config)
创建项目huip-config
创建项目
pom.xml
这是config服务提供项目,需要包含spring-cloud-config-server组件。

在src/main/resources中新建文件bootstrap.yml。这里,用本地路径配置。如果把配置文件放置到git服务中,则active的改成git,配置相应的uri,username,password连接git。内容如下:
server:
port: 8886
spring:
application:
name: huip-config-server
profiles:
active: native
cloud:
config:
server:
native:
search-locations: classpath:/config
# git:
# uri: *****************************
# username: *********
# password: *********
management:
security:
enabled: false
eureka:
instance:
leaseRenewalIntervalInSeconds: 10
statusPageUrlPath: /admin/info
healthCheckUrlPath: /admin/health
non-secure-port: ${server.port:8886}
prefer-ip-address: true
metadata-map:
instanceI-i: ${spring.application.name}:${random.value}
client:
service-url:
defaultZone: http://${eureka.host:localhost}:${eureka.port:8761}/eureka
在src/main/resources下新建文件夹config。把各项目的配置文件放置到这个目录下。
运行服务
huip-user项目修改:
- 新建bootstrap.yml
spring:
application:
name: huip-user-server
cloud:
config:
enabled: true
discovery:
enabled: true
service-id: huip-config-server
eureka:
instance:
non-secure-port: ${server.port:8180}
prefer-ip-address: true
metadata-map:
instance-id: ${spring.application.name}:${random.value}
client:
service-url:
defaultZone: http://${eureka.host:localhost}:${eureka.port:8761}/eureka
- 将application.yml移到huip-config/src/main/resources/config目录下,改名为huip-user-server.yml
启动服务的顺序为: - huip-eureka
启动完成后,访问http://localhost:8761/
eureka
现在还没有服务被发现。 - huip-config
启动完成后,在http://localhost:8761中就发现了一个服务
配置中心服务 -
其它服务就无顺序要求了。这里就加入huip-user服务进行测试
启动完成user服务
用户服务
再做前面用户服务的测试。得到相同的结果
用户服务测试
