[redisson]redis集群模式下,RMapCache报unable to decode data.

redis集群模式下调用RMapCach.keySet()获取所有key,或者RMapCache.readAllValues()获取所有值。应该能正常返回。

但是,当调用以上两个方法后,报"unable to decode data."

public void myTest(RedissonClient redissonClient) {
     RMapCache<String, User> mapCache = redissonClient.getMapCache("myMapCache");

    mapCache.put("firstUser", new User("redisson1", 5), 1, TimeUnit.MINUTES);
    mapCache.put("secondUser", new User("redisson2", 6), 1, TimeUnit.MINUTES);

    User user = mapCache.get("firstUser");
    System.out.println("get first user--->" + user.toString());

    mapCache.readAllValues().forEach(value -> {
        System.out.println("value-->" + value.toString());
    });

    mapCache.keySet().forEach(key -> {
        System.out.println("all keys-->" + key);
}

如果直接配置spring.redis.host和spring.redis.port来连接redis,以上方法不会报错。但是如果使用spring.redis.cluster.nodes集群模式连接,就会有问题。

@@今天发现,跟是否集群好像还没关系。正常运行的程序,我只要修改了getMapCache=("我定义的key")方法中的参数key的值,就会报下面的错误。key我确认是没有使用过的,是我随意输入的值。但是有时候随意输入的值,程序又能正常。实在找不到规律。 @jackygurui

@KavenSu 这个问题确实是和集群有关,在集群发生了槽点移动的时候会触发该问题。不过这个问题已经被https://github.com/redisson/redisson/commit/21ac3d81c17c0488ee33cb87e5e46b3fb893ec93 修复了,更新一下Redisson的版本就行。

@jackygurui 我用的版本是Redisson 3.9.1,这个貌似已经是最新的版本了。您说要更新到哪个版本?

@KavenSu 等这周发的版本吧,包含了其他有关MOVE的修复。

3.10.0版本已经发布了
