redis - 在 Jedis 中获得异常

Question

我有时在访问 Jedis 时遇到以下异常。

异常(exception)情况 1:

    java.lang.ClassCastException: java.lang.Long cannot be cast to [B
    at redis.clients.jedis.Connection.getBinaryBulkReply(Connection.java:204)
    at redis.clients.jedis.Connection.getBulkReply(Connection.java:193)
    at redis.clients.jedis.Jedis.get(Jedis.java:89)

异常(exception) 2:

redis.clients.jedis.exceptions.JedisDataException: ERR Protocol error: invalid bulk length
    at redis.clients.jedis.Protocol.processError(Protocol.java:113)
    at redis.clients.jedis.Protocol.process(Protocol.java:131)
    at redis.clients.jedis.Protocol.read(Protocol.java:200)
    at redis.clients.jedis.Connection.readProtocolWithCheckingBroken(Connection.java:285)
    at redis.clients.jedis.Connection.getBinaryBulkReply(Connection.java:204)
    at redis.clients.jedis.Connection.getBulkReply(Connection.java:193)
    at redis.clients.jedis.Jedis.get(Jedis.java:89)

谁能帮我解决这个问题？

Answer 1

我认为这不是 Jedis 错误。 Redis 有各种批量长度的限制，并且没有很好地记录。看this question例如。并查看多批量长度限制 in Redis source code :

If you total response more than 512*1024*1024 bytes your will catch invalid bulk length error (line 1118).
