1.Spring Cloud Config 分布式配置
a.Config服务器
①新建springboot项目，依赖选择Config Server
②pom文件关键依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent> <dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency> ...... </dependencies> ......
③application.yml文件
spring:
application:
name: config-server
profiles:
#配置文件在本地
active: native
#配置文件的目录
cloud:
config:
server:
native:
search-locations: classpath:/config server:
port: 8101
④启动类添加注解@EnableConfigServer
@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication { public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
} }
⑤在resources下新建config/commom-dev.properties，用于测试
test.name=vettel
test.password=111111
⑥启动后访问 http://localhost:8101/common/dev 可查看配置文件信息，访问路径有如下几种
/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties
注：对于resources下的config/commom-dev.properties，{application}为文件名"commom"，{profile}为环境名"dev"，{label}为路径名"config"。
b.Config客户端
①新建springboot项目，依赖选择 Config Client 、Web
②pom文件关键依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent> <dependencies>
<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> ...... </dependencies> ......
③bootstrap.yml文件
spring:
application:
name: config-client
cloud:
config:
uri: http://localhost:8101
profile: dev
name: common server:
port: 8102
注意：此处需要将配置写入bootstrap.yml（会优先于application.yml加载）中，因为config的配置是优先于application.yml加载的，否则会报错。
④具体使用
@SpringBootApplication
@RestController
public class ConfigClientApplication { public static void main(String[] args) {
SpringApplication.run(ConfigClientApplication.class, args);
} @Value("${test.name}")
String name;
@Value("${test.password}")
String password; @RequestMapping(value="/getConfig")
public String getConfig(){
return "name[" + name + "], password[" + password + "]";
} }
