Spring Cloud之Config

Spring Cloud中通过子项目spring-cloud-config实现了基于git、svn等的分布式配置管理，为微服务的构建提供便利条件。

http访问规则

/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties

application：应用名称，对应客户端配置中的spring.config.name

profile:活动配置文件标识

label: 版本

服务端配置

1、pom.xml中依赖

<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-config-server</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

2、bootstrap.yml配置项

server:
  port: 8888
spring:
  cloud:
    config:
      server:
        git:
#          uri: https://github.com/hjguang/{application}
            uri: https://github.com/hjguang/cloud-config
management:
  security:
    enabled: false

3、启动主程序，添加相应注解

@EnableConfigServer
@SpringBootApplication
public class ConfigServerApp {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		SpringApplication.run(ConfigServerApp.class, args);

	}

}

4、启动验证 http://localhost:8888/env 1、pom.xml添加依赖

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

2、bootstrap.yml

spring:
  application:
    name: config-client
  cloud:
    config:
      uri: http://localhost:8888
 #     profile: ${profile}

server:
  port: 8090

management:
  security:
    enabled: false

3、客户端获取配置代码

@RestController
@SpringBootApplication
public class ConfigClientApp {

	@Value("${db.url}") String url;
	@Value("${db.username}") String userName;
	@Value("${db.password}") String password;
	
	@RequestMapping("/dbconfiginfo")
	public String getValue() {
		return "URL :" + url + " UserName:" + userName + " Password:" + password;
	}
	
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		SpringApplication.run(ConfigClientApp.class, args);
	}

}

4、结果查看：http://localhost:8090/dbconfiginfo URL :cc_url UserName:cc_user1 Password:cc_pw 启动客户端时，添加参数--profile=test,客户端将获取配置仓库中 config-client-test.properties中的配置内容显示结果： URL :url-test UserName:test-u Password:test-pw 服务端配置文件的git url改为： uri: https://github.com/hjguang/{application} 示例结果： URL :url-test UserName:test-u Password:test-pw 项目地址 https://github.com/hjguang/spring-cloud
