spring cloud config使用mysql存储配置文件

3.application.properties:
spring.application.name=config-server-db
server.port=10020spring.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
@SpringBootApplicationpublic classConfigServerBootstrap {public static voidmain(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。
