spring cloud config搭建借助sts(spring官方版eclipse)

第一步：创建项目

经过上述操作生成了项目

第二步：引入必要的pom文件

附上pom.xml

第三步：编写配置文件

需要做的

（1）设置端口

（2）设置服务名

（3）读取配置信息方式：native使用本地属性文件，jdbc从数据库中读取

（4）配置数据源

（5）配置查询配置信息的sql

附上配置文件

#配置工程启动端口
server.port=8000

spring.application.name=config-center


#读取配置信息方式：native使用本地属性文件，jdbc从数据库中读取
spring.profiles.active = jdbc
#属性文件应用场景标识，配置文件命名是有规则的，规则为应用场景的${spring.application.name}-${spring.cloud.config.profile}.properties
#spring.cloud.config.profile=configInfo
#属性文件地址，只要指定文件夹的路径，在工程中格式举例为classpath:/properties,配置文件在本地但不在工程中格式举例为：E:/properties
#spring.cloud.config.server.native.searchLocations=classpath:/properties
spring.cloud.config.server.jdbc=true
spring.cloud.config.server.jdbc.sql=SELECT key_info, value_info from cc_config_info where (application_name=? or application_name='GLOBAL') and profile=? and label=?

#####数据库配置信息#####
spring.datasource.name: hx_config
spring.datasource.url: jdbc:mysql://10.5.200.151:3306/hx_config?useUnicode=true&characterEncoding=utf8&autoReconnect=true
spring.datasource.username: examkw
spring.datasource.password: exama1r1
spring.datasource.driver-class-name: com.mysql.jdbc.Driver

# 使用druid数据源

spring.datasource.testOnBorrow: false
spring.datasource.testOnReturn: false
spring.datasource.poolPreparedStatements: true
spring.datasource.maxPoolPreparedStatementPerConnectionSize: 20
spring.datasource.maxOpenPreparedStatements: 20

数据库表结构

CREATE TABLE `cc_config_info` (
  `config_info_id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
  `key_info` varchar(100) DEFAULT NULL COMMENT '属性名',
  `value_info` varchar(255) DEFAULT NULL COMMENT '属性值',
  `application_name` varchar(100) DEFAULT NULL COMMENT '应用名，GLOBAL为全局',
  `label` varchar(20) DEFAULT 'master' COMMENT '配置标识',
  `profile` varchar(20) DEFAULT 'configInfo',
  `remark` varchar(255) DEFAULT NULL COMMENT '备注',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`config_info_id`)
) ENGINE=MyISAM AUTO_INCREMENT=1055 DEFAULT CHARSET=utf8 COMMENT='配置信息';
