使用 consul
可以通过 Consul官网 下载和安装 Consul。
开发使用
使用Consul需要确保下面的软件包引入:
<dependency>
<groupId>org.apache.servicecomb</groupId>
<artifactId>config-consul</artifactId>
<version>x.x.x</version>
</dependency>
然后在配置文件 applcation.yml 中增加如下配置项:
servicecomb:
config:
consul:
enabled: true
host: localhost
port: 8500
acl-token: ''
watch-seconds: 8
- 配置项说明
配置项 | 默认值 | 是否必选 | 含义 |
---|---|---|---|
servicecomb.config.consul.enabled | true | 是 | 是否启用consul。 |
servicecomb.config.consul.host | localhost | 是 | consul的ip |
servicecomb.config.consul.port | 8500 | 是 | consul的端口 |
servicecomb.config.consul.acl-token | null | 否 | 当服务端启用ACL认证后,必须设置该值 |
servicecomb.config.consul.watch-seconds | 8 | 是 | 监听配置更新检查频率,在1-9之间,单位秒 |
-
说明 ACL的开启参考注册中心Consul的ACL开启步骤

配置中心增加配置
consul 使用下面的配置结构和环境(Environment)、应用(Application)、服务(Service)、版本(Version)、Tag对应, 配置级别优先级从低到高。
