Vert.x Native, RedisClient

This tutorial will introduce how to use Redis in zero system.

1. Configuration

This chapter is duplicated with D10102 - Configuration, vertx-redis.yml, because that's the preparing steps for redis client.

1.1. vertx.yml

Be sure the extension up.god.file name existing in lime node:

zero:
  lime: redis
  vertx:
    instance:
    - name: vx-zero
      options:
        # Fix block 2000 limit issue.
        maxEventLoopExecuteTime: 30000000000

1.2. vertx-inject.yml

redis: io.vertx.mod.plugin.redis.RedisInfix

1.3. vertx-redis.yml

redis:
  host: 0.0.0.0
  port: 6379

Just like vertx-mysql.yml configuration, here all the redis node keys are native supported by vert.x, you can provide all the native configuration keys to redis in zero system.

2. Source Code

package up.god.micro.redis;

import io.vertx.redis.RedisClient;
import io.vertx.up.annotations.EndPoint;

import io.zerows.annotations.infix.Redis;
import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Path("")
@EndPoint
public class RedisActor {
    @Redis
    private transient RedisClient client;

    @Path("/api/redis")
    @GET
    public String sayRedis(final String name) {
        System.out.println(this.client);
        return "Redis, " + name;
    }
}

3. Summary

Here you can inject RedisClient based on above code.
