Constructor Detail

ReactiveRedisStreamMessageHandler

public ReactiveRedisStreamMessageHandler(ReactiveRedisConnectionFactory connectionFactory,
                                         String streamKey)

Create an instance based on provided ReactiveRedisConnectionFactory and key for stream.

Parameters:

connectionFactory - the ReactiveRedisConnectionFactory to use

streamKey - the key for stream

ReactiveRedisStreamMessageHandler

public ReactiveRedisStreamMessageHandler(ReactiveRedisConnectionFactory connectionFactory,
                                         Expression streamKeyExpression)

Create an instance based on provided ReactiveRedisConnectionFactory and expression for stream key.

Parameters:

connectionFactory - the ReactiveRedisConnectionFactory to use

streamKeyExpression - the SpEL expression to evaluate a key for stream

Method Detail

setSerializationContext

public void setSerializationContext(RedisSerializationContext<String,?> serializationContext)

setHashMapper

public void setHashMapper(@Nullable
                          HashMapper<String,?,?> hashMapper)
