 3.application.properties:

spring.application.name=config-server-db
server.port=10020

spring.profiles.active=jdbc

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

spring.datasource.url=jdbc:mysql://localhost:3306/config-server-db
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

flyway.locations=/schema

4.V1_Base_version.sql:

CREATE TABLE `properties` (
  `id` int(11) NOT NULL,
  `key` varchar(50) NOT NULL,
  `value` varchar(500) NOT NULL,
  `application` varchar(50) NOT NULL,
  `profile` varchar(50) NOT NULL,
  `label` varchar(50) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

5.启动项：

@EnableConfigServer
@SpringBootApplication
public class ConfigServerBootstrap {

    public static void main(String[] args) {
        ApplicationContext context = SpringApplication.run(ConfigServerBootstrap.class);

        JdbcTemplate jdbcTemplate = context.getBean(JdbcTemplate.class);
        jdbcTemplate.execute("delete from properties");
        jdbcTemplate.execute("INSERT INTO properties VALUES(1, 'com.didispace.message', 'test-stage-master', 'config-client', 'stage', 'master')");
        jdbcTemplate.execute("INSERT INTO properties VALUES(2, 'com.didispace.message', 'test-online-master', 'config-client', 'online', 'master')");
        jdbcTemplate.execute("INSERT INTO properties VALUES(3, 'com.didispace.message', 'test-online-develop', 'config-client', 'online', 'develop')");
        jdbcTemplate.execute("INSERT INTO properties VALUES(4, 'com.didispace.message', 'hello-online-master', 'hello-service', 'online', 'master')");
        jdbcTemplate.execute("INSERT INTO properties VALUES(5, 'com.didispace.message', 'hello-online-develop', 'hello-service', 'online', 'develop')");

    }
}

只需要建立一个

config-server-db数据库就行，表不用自己创建，

flyway会自动帮你创建好数据库表。直接运行项目就行，访问方式和使用git获取配置文件的方式一样，返回的数据类型也是一样的。

值得注意的是配置中心想要用mysql存储配置文件，必须是

Edgware版本才行，

Dalston版本不行。
