我正在尝试导入RedisStreamCommands。我可以导入它,但可以导入RedisCommands。我认为它需要依赖。我不知道那是什么,请帮帮我。

RedisCommands<String, String> syncCommands = connection.sync();
RedisStreamCommands<String, String> streamCommands = connection.sync();
syncCommands.set("key_1", "Hello, Redis!");
Map<String, String> body =  Collections.singletonMap("key", "value");
String messageId = streamCommands.xadd("my-stream", body);

我曾这样尝试过:RedisStreamCommands上显示错误。
import java.util.Collections;
import java.util.Map;
import java.util.concurrent.TimeUnit;

import io.lettuce.core.RedisClient;
import io.lettuce.core.RedisURI;
import io.lettuce.core.api.StatefulRedisConnection;
import io.lettuce.core.api.sync.*;
import io.lettuce.core.api.sync.RedisCommands;
import io.lettuce.core.cluster.RedisClusterClient;
import io.lettuce.core.cluster.api.StatefulRedisClusterConnection;
import io.lettuce.core.cluster.api.sync.RedisAdvancedClusterCommands;

public class LettuceDemo {

    public static void main(String[] args) {

        RedisClient redisClient = RedisClient.create("redis://15m4madm4bd6ypfqtc353wfq4q292brk@expeditious-ironwood-6027.redisgreen.net:11042/0");
        StatefulRedisConnection<String, String> connection = redisClient.connect();
        RedisCommands<String, String> syncCommands = connection.sync();
        RedisStreamCommands<String, String> streamCommands = connection.sync();
        syncCommands.set("key_1", "Hello, Redis!");
        Map<String, String> body =  Collections.singletonMap("key", "value");
        String messageId = streamCommands.xadd("my-stream", body);

        connection.close();
        redisClient.shutdown();

    }

}

最佳答案

接口(interface) io.lettuce.core.api.sync.RedisStreamCommands 在Redis版本5.1中引入;您最有可能使用的是不包含它的早期版本。

因此,基本上,因此,您应该检查类路径和Redis的版本,并在必要时将其调整为5.1+版本。您可以从以下位置获取它:https://lettuce.io/docs或查看文档以获取更多详细信息。

希望能帮助到你。
