RedisClient.srandmember介绍

[英]Get one or multiple random members from a set
[中]从集合中获取一个或多个随机成员

代码示例

代码示例来源：origin: xenv/gushici

/**
 * @param message example: {format: "png", categories: [shenghuo, buyi]}
 */
private void getGushiciFromRedis(Message<JsonObject> message) {
  JsonArray realCategory = new JsonArray()
    .add("png".equals(message.body().getString("format")) ? "img" : "json")
    .addAll(message.body().getJsonArray("categories"));
  checkAndGetKey(realCategory)
    .compose(key -> Future.<String>future(s -> redisClient.srandmember(key, s))) // 从 set 随机返回一个对象
    .setHandler(res -> {
      if (res.succeeded()) {
        message.reply(res.result());
      } else {
        if (res.cause() instanceof ReplyException) {
          ReplyException exception = (ReplyException) res.cause();
          message.fail(exception.failureCode(), exception.getMessage());
        }
        message.fail(500, res.cause().getMessage());
      }
    });
}
