how redisson serialize long

Question

I use redisson to store Long values:

        RSet<Long> set = client.getSet("myset");
        set.add(Long.valueOf(n));

But I get an unreadable value:

> SMEMBERS myset
1) "\t\x84\xe2\x02"

How can I retrieve this value without redisson?

Answer 1

The default codec for Redisson from version 3.13.0 is MarshallingCodec and before that it was FSTCodec. Both of these serialize to binary formats which are not human readable.

To serialize long and integer values Redisson offers LongCodec. The corresponding code will look like this:

RSet<Long> set = client.getSet("myset",LongCodec.INSTANCE);
set.add(Long.valueOf(n));
