Spring Cloud-Nacos 使用配置中心

只提供使用demo,原理请自行百度

1.引入项目依赖

2.添加bootstrap配置,因为springcloud config加载优先级需要配置在此文件中,系统级别配置

3.添加dev命名空间

4.在dev环境下配置中心添加配置信息

*******重点*******

        DataId:项目启动,根据你项目中bootstrap文件中的配置信息组装成nacos上的DataId读取配置信息

                      DataId = ${spring.application.name}-${spring.profile.active}.${file-extension}

启动项目可以看到加载需要加载的信息:

具体代码如下:

依赖配置:

<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
			<version>0.9.0.RELEASE</version>
</dependency>

Bootstrap.yml配置:

spring:
  profiles:
    active: dev  
  application:
    name: ebiz-agent-center
  cloud:
    nacos:
      config:
        server-addr: 118.190.5.81:8848   
        file-extension: "yaml"  
        namespace: "05a4b23f-aff1-4a75-b1ef-e25a51b57d8a" 
    
#server-addr:nacos地址
#profiles.active:环境地址
#namespace:命名空间id
#file-extension:文件后缀名,目前支持yaml或properties
#huaxiaozhou.add 20190819

nacos配置:

server:
  port: 5555
  servlet:
    context-path: /agent
spring:
  cloud:
    nacos:
      discovery:
        server-addr: 118.190.1.84:8848
        namespace: "05a4b23f-aff1-4a75-b1ef-e25a51b57b1a"
  datasource:
        driverClassName: com.mysql.jdbc.Driver
        jdbc-url: 
        username: 
        password: 
        filters: stat
        maxActive: 1000
        initialSize: 1
        maxWait: 60000
        minIdle: 1
        timeBetweenEvictionRunsMillis: 60000
        minEvictableIdleTimeMillis: 300000
        validationQuery: SELECT COUNT(*) FROM DUAL
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        poolPreparedStatements: true
        maxOpenPreparedStatements: 100
  redis:
    host: 
    port: 7003
    database: 0
    password: 
    timeout: 4000
    lettuce:  
      lettuce:
        pool:
          max-active: 200 
          max-idle: 20 
          min-idle: 5 
          max-wait: 2000
