springboot配置文件抽离 git管理统 配置中心详解

springboot配置文件抽离，便于服务器读取对应配置文件，避免项目频繁更改配置文件，影响项目的调试与发布

1.创建统一配置中心项目conifg

1）pom配置依赖

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.0.6.RELEASE</version>
  <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  <java.version>1.8</java.version>
  <spring-cloud.version>Finchley.SR2</spring-cloud.version>
</properties>

<dependencies>
  <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-server</artifactId>
  </dependency>
  <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
  </dependency>

  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
  </dependency>

  <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bus-amqp</artifactId>
  </dependency>

  <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-monitor</artifactId>
  </dependency>
</dependencies>

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-dependencies</artifactId>
      <version>${spring-cloud.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

2）yml文件配置

spring:
 application:
  name: config
 cloud:
  config:
   server:
    git:
     uri: https://gitee.com/XXXX/XXXXXX.git
     username: XXXXXXX
     password: XXXXXXXXX
eureka:
 client:
  service-url:
   defaultZone: http://localhost:8000/eureka/
management:
 endpoints:
  web:
   expose: "*"

2.创建git私有项目config-repo 用于存放配置文件

3.配置项目 可以看到对应的配置文件内容

http://localhost:8002/XXXXX/user-dev.yml

4.配置客户端读取配置文件

1）客户端配置pom

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-config-client</artifactId>
</dependency>

2）客户端yml文件配置

spring:
 application:
  name: XXXXXX
 cloud:
  config:
   discovery:
    enabled: true
    service-id: CONFIG
   profile: dev



eureka:
 client:
  service-url:
   defaultZone: http://localhost:8000/eureka/
 instance:
  prefer-ip-address: true
  lease-renewal-interval-in-seconds: 1 # 单机时关闭eureka 保护模式
  lease-expiration-duration-in-seconds: 2
