Zerdis is a Distributed externalise configuration with Spring Cloud + Redis. It helps to manage spring boot configuration for propertysource by implementing spring cloud config. Features include managing the configuration across the services through the Redis NoSQL memory data store by using pub/sub mode.
If you have the configure-server who manage the configuration with connected to redis by publish with specific topic, after that configure-client can subscribe to the topic. You can broadcast all the client or specific client configuration by just call to the configure-server /redis-refresh endpoint.
Adding depedency to your application:
<dependency>
<groupId>io.zerdis</groupId>
<artifactId>zerdis-integration</artifactId>
<version>${version}</version>
</dependency>
Adding @EnableRedisConfigureServer to your application.
@SpringBootApplication
@EnableRedisConfigureServer
public class CofigureServerApplication {
public static void main(String[] args) {
SpringApplication.run(CofigureServerApplication.class, args);
}
}
You also need to add the boostrap.yaml in your spring boot application.
spring:
redis:
port: 6379
host: localhost
application:
name: redis-configure-server
profiles:
active:
- dev
We need to put the redis configuration like port, host and password if required.Because on the bootstrap both configure-server and configure-client need to fetch the configuration from redis and publish for the configure-server and subscribe for configure-client.
By default configure-server is exposing the /redis-refresh endpoint. It's sending the message Refresh properties. to the default topic spring-redis-propertysource. if you want to change the default topic. You can set in .properties file
configure.redis.topic=my-spring-boot-redis-topic.
Like configure-server, you just @EnableRedisConfigureClient to your spring boot application.
@SpringBootApplication
@EnableRedisConfigureClient
public class ConfigureClientApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigureClientApplication.class, args);
}
}
You also need to add the boostrap.yaml in your spring boot application.
spring:
redis:
port: 6379
host: localhost
application:
name: redis-configure-client
profiles:
active:
- dev
For the queue topic is the same configure-server. If you want to change the topic name fo configure-server or configure-client they are pair and must be the same.
