spring-cloud-stream3.0 batch-mode is true consumer data Can't convert value of class - serialization

Question

config info
spring:
kafka:
consumer:
max-poll-records: 5
cloud:
stream:
instance-count: 5
instance-index: 0
kafka:
binder:
brokers: 127.0.0.1:9092
auto-create-topics: true
auto-add-partitions: true
min-partition-count: 5
bindings:
log-data-in:
destination: log-data1
group: log-data-group
contenttype: text/plain
consumer:
partitioned: true
batch-mode: true
log-data-out:
destination: log-data1
contentType: text/plain
producer:
use-native-encoding: true
partitionCount: 5
# configuration:
# key.serializer: org.apache.kafka.common.serialization.StringSerializer
# value.serializer: org.apache.kafka.common.serialization.ByteArraySerializer
send kafka code:
LogData logData = new LogData();
logData.setId(1)
logData.setVer("22")
MessageChannel messageChannel = logDataStreams.outboundLogDataStreams();
boolean sent = messageChannel.send(MessageBuilder.withPayload(logData).setHeader("partitionKey", key).build());
consumer data listener kafka topic
I think there is an error in processing the data type in kafka, there is no problem, there is no less setting, why is the conversion type error when consuming kafka information, bytes cannot know to convert an entity class
The code here is the consumption data, which is the place where the error is reported
#StreamListener(LogDataStreams.INPUT_LOG_DATA)
public void handleLogData(List<LogData> messages) {
System.out.println(messages);
messages.parallelStream().forEach(item -> {
System.out.println(item);
});
}
Define topic identifier
public interface LogDataStreams {
String INPUT_LOG_DATA = "log-data-in";
String OUTPUT_LOG_DATA = "log-data-out";
String INPUT_LOG_SC = "log-sc-in";
String OUTPUT_LOG_SC = "log-sc-out";
String INPUT_LOG_BEHAVIOR = "log-behavior-in";
String OUTPUT_LOG_BEHAVIOR = "log-behavior-out";
#Input(INPUT_LOG_DATA)
SubscribableChannel inboundLogDataStreams();
#Output(OUTPUT_LOG_DATA)
MessageChannel outboundLogDataStreams();
}
I think there is an error in processing the data type in kafka, there is no problem, there is no less setting, why is the conversion type error when consuming kafka information, bytes cannot know to convert an entity class
Error in last run:
Caused by: org.apache.kafka.common.errors.SerializationException: Can't convert value of class com.xx.core.data.model.LogData to class org.apache.kafka.common.serialization.ByteArraySerializer specified in value.serializer
Caused by: java.lang.ClassCastException: com.xx.core.data.model.LogData cannot be cast to [B
Please help me, how to solve this problem
