sparkstreaming-kafka乱码

[code-guy]

//kafka发送信息
#kafka Producer配置
value.serializer=org.apache.kafka.common.serialization.ByteArraySerializer
key.serializer=kafka.serializer.StringEncoder
producer.send(new ProducerRecord<String, byte[]>(topic, key, SerializationUtils.serialize(value)));
//sparkstreaming消费信息
KafkaUtils.createDirectStream[String, String, StringDecoder, StringDecoder](scc, kafkaParam, topics)
//sparkstreaming端乱码

有没有遇到的，求解！
