springboot配置文件抽離--git管理統一配置中心

springboot配置文件抽離，便於服務器讀取對應配置文件，避免項目頻繁更改配置文件，影響項目的調試與發布

1.創建統一配置中心項目conifg

1）pom配置依賴

<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.創建git私有項目config-repo 用於存放配置文件

3.配置項目 可以看到對應的配置文件內容
http://localhost:8002/XXXXX/user-dev.yml

4.配置客戶端讀取配置文件
1）客戶端配置pom

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-client</artifactId>
</dependency>
2）客戶端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 # 單機時關閉eureka 保護模式
    lease-expiration-duration-in-seconds: 2
