SpringCloud 整合Nacos

1.添加bootstarp.yml配置文件

server:
  port: 9090

#nacos注册中心,配置中心
spring:
  profiles:
    active: dev
  application:
    name: jin-he-sign
  cloud:
    nacos:
#      服务发现配置
      discovery:
#       Nacos服务端ip端口
        server-addr: 127.0.0.1:8848
#       命名空间(主要起隔离作用,通常用来区分测试,开发环境下的配置)
        namespace: e8d801ca-c6bb-40d8-863b-8ee91b6679ad
#     配置中心
      config:
#       开启配置
        enabled: true
        server-addr: 127.0.0.1:8848
#       配置文件名称(对应Nacos中的data_id,命名规则一般为applicationName+active级别+文件后缀)
        name: jin-he-sign-dev
#       文件后缀
        file-extension: yaml
        namespace: e8d801ca-c6bb-40d8-863b-8ee91b6679ad
#       组id(用来隔离,一般用来区分不同的项目)
        group: DEFAULT_GROUP
#
        refresh-enabled: true

#        ext-config[0]:
#          data-id: ext-config-common01.properties
#          group: message-ext.properties
#          refresh: true

这里config下name属性可配可不配,规则如下:

　　1.1采用application.name/config.name+后缀名加载,现在之后再加载application.name/config.name+"-"+"配置文件级别(dev,prod)".后缀名;

2.添加maven依赖

        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>

3.再nacos创建配置文件

spring:
  redis:
    conn-timeout: 30000
    database: 1
    host: {ip}
    max-active: 80
    max-idle: 10
    max-wait: -1
    min-idle: 5
    password: {password}
    port: 6379
    ssl: false
  crypto:
    key: {加密密钥}
    request:
      decrypt:
        enabled: true
  datasource:
    druid:
      connect-properties:
        password: {加密后的密钥}
      driver-class-name: com.mysql.jdbc.Driver
      filter:
*这里开启druid的stat监控
        stat:
          enabled: true
          log-slow-sql: true
          slow-sql-millis: 200
*这里开启druid的sql日志输出
        slf4j:
          enabled: true
*连接的获取不打印
          statement-close-after-log-enabled: false
*连接的归还不打印
          statement-prepare-after-log-enabled: false
      initial-size: 2
      max-active: 10
      max-wait: 60000
      min-evictable-idle-time-millis: 300000
      min-idle: 2
      password: gdriver@2020
      test-on-borrow: false
      test-on-return: false
      test-while-idle: true
      time-between-eviction-runs-millis: 60000
      url: {url}
      username: {name}
      validation-query: select 1
server:
  servlet:
    context-path: /e-sign

file:
  tmp:
    dir: E:\uploadtempdir
mybatis:
  mapper-locations: classpath*:mybatis/*.xml
print:
  tmp:
    dir: C:\Kobe\saaserp\myproject\ui\my-erp-ui\static\print

logging: 
  config: classpath:logback-spring.xml        

 refresh 要配合
@RefreshScope 使用

添加再需要读取配置的类上
