我是redisReact式实现的新手。我正试图建立一个后端,利用redis上localhost:6379 (默认位置)。现在,文档中说“如果要连接到一个redis服务器,我们不需要添加任何配置代码localhost:6379."
所以我像往常一样开始了我的redis:

提出了一个简单的请求

{
    "uid":"123",
    "message":"hello world"
}

到这个控制器

@PostMapping("/api/v1/space/post/")
@ResponseBody
public ResponseEntity<String> postMessage(@RequestBody Message message) throws Exception {
    if(messageService.postMessage(message.getUid(), message.getMessage())){
        return ResponseEntity.ok("it works!");
    } else{
        return ResponseEntity.badRequest().body("something's wrong");
    }

}

一切都很顺利,日志甚至声明哈希已经创建。但是,当我执行redis cli并检查任何键时,什么都没有。

我也试着用莴苣连接工厂连接

@Bean
public ReactiveRedisConnectionFactory reactiveRedisConnectionFactory() {
    return new LettuceConnectionFactory("localhost", 6379);
}

但是运气不好,我猜SpringBoot是以某种方式连接到一个嵌入式redis的,这不是我想要的,那么如何连接到redis示例呢?

以下是消息repo&service repo返回一个monognorePublisher,在文档中,mono要么返回一个元素,要么返回一个错误,这是一个错误吗
回购:

private final ReactiveRedisOperations<String, Message> redisTemplate;

    public MessageRepository(ReactiveRedisOperations<String, Message> redisOperations) {
        this.redisTemplate = redisOperations;
    }

    public Mono<Void> save(String authorId, String msg) {
        Message message = new Message(authorId, msg);
        Mono<Void> res = Mono.when(redisTemplate.<String, Message>opsForHash().put("space", message.getId(), message), 
        redisTemplate.opsForZSet().add(message.getUid(), message, message.getTimestamp().toEpochDay())).then();
        System.out.println(res.toString());
        return res;
    }

服务:

@Autowired
    private MessageRepository repo;
public Boolean postMessage(String authorId, String msg) throws Exception {
        try{
            repo.save(authorId, msg);
        }
        catch (Exception e){
            throw new Exception(e);
        }
        return true;       
    }

以下是ReactiveRedisoOperation配置:

@Bean
public ReactiveRedisOperations<String, Message> redisOperations(ReactiveRedisConnectionFactory factory) {
    Jackson2JsonRedisSerializer<Message> serializer = new Jackson2JsonRedisSerializer<>(Message.class);

    RedisSerializationContext.RedisSerializationContextBuilder<String, Message> builder = RedisSerializationContext
            .newSerializationContext(new StringRedisSerializer());

    RedisSerializationContext<String, Message> context = builder.value(serializer)
            .hashKey(new StringRedisSerializer()).hashValue(serializer).build();

    return new ReactiveRedisTemplate<>(factory, context);
}
