创建项目
配置文件
启动类
服务
pom文件
验证

一.创建项目
选取Spring Cloud Config作为获取配置组件
Spring Cloud Bus(rabbitmq)作为消息总线组件

创建maven项目flow-config-client01(8751)、flow-config-client02(8752)作为子模块

二.配置文件
1.application-config-client01-dev.yml, 内容如下:

# rabbitmq_config\bus_config
spring:
  rabbitmq:
    host: *.*.*.*
    port: 5672
    username: ***
    password: ***
  cloud:
    bus:
      enabled: true
      trace:
        enabled: true

management:
  endpoints:
    web:
      exposure:
        include: "*"
      cors:
        allowed-origins: "*"
        allowed-methods: "*"

info:
  company.name: org.flowframework
  app.name: config-client01
  app.desc: springcloud-config-client01
  author: robin

2.bootstrap.yml, 内容如下:

server:
  port: 8751

eureka:
  instance:
    lease-renewal-interval-in-seconds: 5
    lease-expiration-duration-in-seconds: 10
  client:
    service-url:
      # 单个配置
#      defaultZone: http://localhost:8761/eureka/
      # 集群配置
      defaultZone: http://127.0.0.1:8761/eureka/, http://127.0.0.1:8762/eureka/

spring:
  application:
    name: config-client
  cloud:
    config:
      label: master
      profile: dev
      uri: http://localhost:8741
      discovery:
        enable: true
        service-id: config-server

注意:
git相关配置必须写在bootstrap.yml中

三.启动类
Application.java

@EnableEurekaClient
@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

四.服务
1.RefreshConfig.java

@Component
@RefreshScope
public class RefreshConfig {

    @Value("${data.env}")
    private String env;
    @Value("${data.user.username}")
    private String username;
    @Value("${data.user.password}")
    private String password;

    public Map<String, Object> getConfig() {
        Map<String, Object> paramMap = new HashMap<>(3);
        paramMap.put("env", env);
        paramMap.put("username", username);
        paramMap.put("password", password);
        return paramMap;
    }

    public String getEnv() {
        return env;
    }

    public void setEnv(String env) {
        this.env = env;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

2.ConfigController.java

@RestController
public class ConfigController {

    @Autowired
    RefreshConfig refreshConfig;

    @RequestMapping("/config")
    public Object getConfig() {
        return refreshConfig.getConfig();
    }
}

五.pom文件
