springcloud config配置中心使用數據庫（h2）模式

1、引入maven依賴   

 <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.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <scope>runtime</scope>
        </dependency>

 

2、開啓配置中心

         爲普通springboot項目增加註解@EnableConfigServer

3、配置數據庫

spring:
  datasource:
      username: sa
      password: sa
      url: jdbc:h2:file:~/h2/config-db
      driver-class-name: org.h2.Driver
  cloud:
       config:
         label: master
         server:
           jdbc: true
  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update
  h2:
    console:
      settings:
        web-allow-others: true
      path: /h2
      enabled: true


spring.cloud.config.server.jdbc.sql: SELECT KEY,VALUE  from spring_cloud_config where APPLICATION=? and PROFILE=? and LABEL=?
