今天药忘吃喽~ 2021-07-24 12:49 728阅读 0赞

**一 代码位置**

[https://github.com/cakin24/spring-cloud-code/tree/master/ch][https_github.com_cakin24_spring-cloud-code_tree_master_ch]12-3

**二 数据库脚本**

CREATE TABLE `PROPERTIES` (
      `ID` int(11) NOT NULL AUTO_INCREMENT,
      `KEY` TEXT DEFAULT NULL,
      `VALUE` TEXT DEFAULT NULL,
      `APPLICATION` TEXT DEFAULT NULL,
      `PROFILE` TEXT DEFAULT NULL,
      `LABLE` TEXT DEFAULT NULL,
      PRIMARY KEY (`ID`)
    ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
    
    INSERT INTO `spring-cloud`.`properties` (`ID`, `KEY`, `VALUE`, `APPLICATION`, `PROFILE`, `LABLE`) VALUES ('3', 'cn.springcloud.book.config', 'I am the mysql configuration file from dev environment.', 'config-info', 'dev', 'master');
    INSERT INTO `spring-cloud`.`properties` (`ID`, `KEY`, `VALUE`, `APPLICATION`, `PROFILE`, `LABLE`) VALUES ('4', 'cn.springcloud.book.config', 'I am the mysql configuration file from test environment.', 'config-info', 'test', 'master');
    INSERT INTO `spring-cloud`.`properties` (`ID`, `KEY`, `VALUE`, `APPLICATION`, `PROFILE`, `LABLE`) VALUES ('5', 'cn.springcloud.book.config', 'I am the mysql configuration file from prod environment.', 'config-info', 'prod', 'master');

**三 测试 **

1 启动config-server-db

2 启动config-client-db

3 浏览器输入 [http://localhost:9096/configConsumer/getConfigInfo][http_localhost_9096_configConsumer_getConfigInfo]

匹配到的配置数据是

INSERT INTO `spring-cloud`.`properties` (`ID`, `KEY`, `VALUE`, `APPLICATION`, `PROFILE`, `LABLE`) VALUES ('3', 'cn.springcloud.book.config', 'I am the mysql configuration file from dev environment.', 'config-info', 'dev', 'master');

匹配到这条数据是由下面SQL语句的where条件所决定。

spring:
      application:
        name: ch12-3-config-server-db
      cloud:
        config:
          server:
            jdbc:
              sql: SELECT `KEY`, `VALUE` FROM PROPERTIES WHERE application =? AND profile =? AND lable =?
