編寫啟動(dòng)類
package com.warmsun.config;
?
import org.springframework.boot.SpringApplication;
import org.springframework.cloud.client.SpringCloudApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
?
/**
* 配置中心
*/
@EnableConfigServer
@SpringCloudApplication
public class SakuraConfigApplication {
public static void main(String[] args) {
SpringApplication.run(SakuraConfigApplication.class,args);
}
}
我們來對(duì)比之前的eureka搭建的主類睡陪，發(fā)現(xiàn)這里我們用的是@SpringCloudApplication注解巴碗，而eureka的主類上用的是@SpringBootApplication 注解蛉签，那我們來看一下SpringCloudApplication注解干了什么事情：
@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@SpringBootApplication
@EnableDiscoveryClient
@EnableCircuitBreaker
public @interface SpringCloudApplication {
}
導(dǎo)入了@SpringBootApplication注解，導(dǎo)入@EnableDiscoveryClient注解，改注解能導(dǎo)入config配置畔咧，不管你是Spring-cloud-config還是其他的例如：Apollo等娶靡，@EnableCircuitBreake 導(dǎo)入一個(gè)斷路器實(shí)現(xiàn)牧牢。@EnableDiscoveryClient和@EnableCircuitBreake 我們可能還不是很了解，先不急姿锭，后面我們會(huì)一一解析
編寫配置
server:
port: 2001
?
spring:
application:
name: service-config
#配置環(huán)境
profiles: dev
cloud:
config:
server:
git:
uri: https://github.com/JamariRay/athena-config.git
#如過你的項(xiàng)目是私有塔鳍，那么在下面配置你的git信息，如果是公開的艾凯，刪除下面的2配置
username: ××××
password: ××××××
?
eureka:
instance:
prefer-ip-address: true
client:
service-url:
defaultZone: http://sakura:Sakura*&^999@${eureka.instance.hostname}:${server.port}/eureka/
編寫其他的微服務(wù)配置
在github上 創(chuàng)建一個(gè)athena-config項(xiàng)目献幔，然后克隆到本地，編寫好后趾诗，push到github蜡感，這樣我們的config項(xiàng)目就能讀取到相應(yīng)微服務(wù)的信息了。
application-dev:
# redis 相關(guān)
spring:
redis:
password:
host: localhost
# 暴露監(jiān)控端點(diǎn)
management:
endpoints:
web:
exposure:
include: '*'
?
# feign 配置
feign:
hystrix:
enabled: true
okhttp:
enabled: true
httpclient:
enabled: false
client:
config:
feignName:
connectTimeout: 10000
readTimeout: 10000
compression:
request:
enabled: true
response:
enabled: true
# hystrix If you need to use ThreadLocal bound variables in your RequestInterceptor`s
# you will need to either set the thread isolation strategy for Hystrix to `SEMAPHORE or disable Hystrix in Feign.
hystrix:
command:
default:
execution:
isolation:
strategy: SEMAPHORE
thread:
timeoutInMilliseconds: 60000
shareSecurityContext: true
?
#請(qǐng)求處理的超時(shí)時(shí)間
ribbon:
ReadTimeout: 10000
ConnectTimeout: 10000
加-dev是因?yàn)楫?dāng)前壞境為開發(fā)環(huán)境恃泪，在service-config項(xiàng)目下已經(jīng)配置了profiles:dev所以這里也要對(duì)應(yīng)郑兴，其他的微服務(wù)配置
# 數(shù)據(jù)源
spring:
datasource:
type: com.zaxxer.hikari.HikariDataSource
driver-class-name: com.mysql.jdbc.Driver
username: root
password: 123456
url: jdbc:mysql://localhost:3306/sakura?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false
好了微服務(wù)注冊(cè)中心就搭好了，更多搭建信息參見spring的官方文檔.
好了搭建微服務(wù)配置中心 就到這里了贝乎，源碼解析我會(huì)在后面分享情连！
