之前Spring Cloud Config基础篇这篇文章介绍了Spring Cloud Config 配置中心基础的实现,今天继续聊下Spring Cloud Config 并结合nacos做服务注册中心,实现多项目、多配置文件、按项目目录划分等功能的配置服务中心。
阅读本篇文章之前,最好要有nacos基础;关于nacos是什么,如何使用,可以参考我的上一篇文章 Spring Cloud Alibaba(一) 如何使用nacos服务注册和发现,或者直接链接到官网教程Nacos 快速开始
该项目用来做配置服务中心,以下贴出关键部分代码
pom.xml

启动类AnConfigServerApplication.java
@SpringBootApplication
@EnableDiscoveryClient
@EnableConfigServer
public class AnConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(AnConfigServerApplication.class, args);
}
}
该项目用来做配置中心客户端测试之一,以下贴出几处关键代码
pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

bootstrap.yml
spring:
application:

cloud:
nacos:
discovery:
server-addr: localhost:8848
config:
name: ${spring.application.name},myconfig
uri: http://localhost:8001/ # config server 配置服务地址
profile: ${spring.profiles.active}
label: master
profiles:
active: pro # 配置文件版本(该示例分为test,dev,pro)
写个配置读取测试类HelloController.java
@RestController
public class HelloController {
@Value("${easy.hello}")
private String hello;
@Value("${easy.myconfig}")
private String myconfig;
@RequestMapping("/hello")
public Map hello() {
Map map = new HashMap<>();
map.put("hello", hello);
map.put("myconfig", myconfig);
return map;
}
}
启动类AnConfigClientApplication.java
@SpringBootApplication
@EnableDiscoveryClient
public class AnConfigClientApplication {
public static void main(String[] args) {
SpringApplication.run(AnConfigClientApplication.class, args);
}
}
以下贴出调整部分代码
pom.xml增加spring-cloud-starter-config依赖
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
</dependencies>
yml配置文件增加bootstrap.yml,把核心配置移到该配置文件
bootstrap.yml
spring:
application:
name: ali-nacos-consumer-feign
cloud:
nacos:
discovery:
server-addr: localhost:8848
config:
name: ${spring.application.name}
uri: http://localhost:8001/ # config server 配置服务地址
profile: ${spring.profiles.active}
label: master
profiles:
active: dev # 配置文件版本(该示例分为test,dev,pro)
编写配置读写测试类HomeController.java
@RestController
@Slf4j
public class HomeController {
@Autowired
private HelloService helloService;
@Value("${easy.hello}")
private String hello;
@GetMapping(value = "/", produces = "application/json")
public String home() {
log.info("-----------------consumer调用开始-----------------");
String param = "云天";
log.info("消费者传递参数:" + param);
String result = helloService.hello(param);
log.info("收到提供者响应:" + result);
return "feign消费者" + result;
}
@RequestMapping("/hello")
public Map hello() {
Map map = new HashMap<>();
map.put("hello", hello);
return map;
}
}
config-repo配置总目录
ali-nacos-config-server 项目GIT的配置目录
ali-nacos-consumer-feign 项目GIT的配置目录
ali-nacos-config-server:配置服务中心,服务名:ali-nacos-config-server,端口:8001
ali-nacos-config-client:配置客户端1(消费端),服务名:ali-nacos-config-client,端口:8002
ali-nacos-consumer-feign:配置客户端2(消费端),服务名:ali-nacos-consumer-feign,端口:9101
首先要启动服务注册中心 nacos
{
name: "ali-nacos-config-client",
profiles: [
"dev"
],
label: null,
version: "5456d7ca31d46e91464b6efd3a0831a8208413d9",
state: null,
propertySources: [ ]
}
{
name: "ali-nacos-config-client",
profiles: [
"test"
],
label: null,
version: "5456d7ca31d46e91464b6efd3a0831a8208413d9",
state: null,
propertySources: [ ]
}
这表示配置能正确从git上加载到了。
{
hello: "ali-nacos-config-client 项目的 dev config",
myconfig: "ali-nacos-config-client 项目的 myconfig config"
}
{
hello: "ali-nacos-config-client 项目的 test config",
myconfig: "ali-nacos-config-client 项目的 myconfig config"
}
表示我git上该项目的2个配置文件都成功读取到了。
访问:http://localhost:9101/hello
返回结果
{
hello: "ali-nacos-consumer-feign 项目的 dev config"
}
表示该项目的配置文件加载成功了
Spring Cloud Alibaba(二) 配置中心多项目、多配置文件、分目录实现
