vertx操作redis
想通过写一个json的配置文件，然后读取，去操作。
我这么写的，读不到配置问题、请问什么原因？

{
  "options": {
    "config": {
      "redis_client_account": {
        "host": "localhost",
        "port": 6379,
        "select": 7,
        "auth": "123"
      },
      "maxPoolSize":200,
      "maxWaitQueueSize":50,
      "connectTimeout":5000,
      "idleTimeout":60
    }
  }
}

public class RedisTest extends AbstractVerticle {
  public static void main(String[] args) {
    Vertx vertx = Vertx.vertx();
    //部署verticle
    vertx.deployVerticle(new RedisTest());


  }

  private static RedisClient redisClient;
  private JsonObject config;

  @Override
  public void init(Vertx vertx, Context context) {
    super.init(vertx, context);
    this.config = context.config();
    JsonObject redisConfig = config.getJsonObject("redis_client_account", new JsonObject());
    System.out.println(redisConfig);

    RedisOptions options = new RedisOptions(redisConfig);
    Redis redis = Redis.createClient(vertx, options);
    RedisAPI api = RedisAPI.api(redis);
    set(api);

    get(api);
  }


  private void set(RedisAPI api) {

  }

  String redisCompressEncryptKey = "key1";

  private void get(RedisAPI api) {
    api.get(redisCompressEncryptKey, req -> {
      String redisCompressEncryptValue;
      if (req.succeeded()) {
        redisCompressEncryptValue = req.result().toString();
        System.out.println(redisCompressEncryptValue);
        if (Boolean.parseBoolean(redisCompressEncryptValue)) {
          System.out.println(redisCompressEncryptValue);
        }
      }
    });
  }

}
