-----------------bootstrap.yml

注：discovery段是添加到consul注册中心的

config段说明：

enabled: true允许配置中心

format:YAML 表示consul中的key-value中的value内容，采用YAML格式，据说有四种 YAML PROPERTIES KEY-VALUE FILES

prefix: config 表示consul用于存储配置的文件夹根目录名为config

defaultContext: application 表示配置文件对应的默认应用名称（优先获取当前服务名称配置，没有的到application里找）

profileSeparator: ',' 表示如果有多个profile(eg: 开发环境dev，测试环境test...) ，则key名中的profile与defaultContext之间，用什么分隔符来表示（例如config/springtest-service,dev/data）

data-key: data 表示最后一层节点的key值名称，一般默认为data

 

---------------TestConfig.java

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;@ConfigurationProperties(prefix = "test-config")
@Configuration
@Data
public class TestConfig {private String testValue;
}

--------------App.java

@EnableDiscoveryClient
@RestController
@SpringBootApplication
public class SpringtestServerApplication {@Autowiredprivate DiscoveryClient discoveryClient;@Value("${test.testValue}")private String testValue;@Autowiredprivate TestConfig  testConfig;public static void main(String[] args) {SpringApplication.run(SpringtestServerApplication.class, args);}@RequestMapping("/test")public String test(String id) {return "test"+id+"/"+testValue+"/"+testConfig.getTestValue();}
}

这里面采用了两种获取配置的方式

@Value

和

@ConfigurationProperties

都能进行配置获取，但是后者可以实现配置更新后动态更新

 

-------------配置

consul页面上添加key为：

config/springtest-service/data

value为：

test:testValue:  consul--asdf34
testConfig:test-value: consul123--asdf34

 

-------------配置优先级

config/testApp,dev/

config/testApp/

config/application,dev/

config/application/
