i want to serialize and deserialize the message with
ProtobufMessageConverter so i define RocketMQMessageConverter like this
@Bean
public RocketMQMessageConverter
rocketMQMessageConverter(ProtobufMessageConverter protobufMessageConverter){
RocketMQMessageConverter rocketMQMessageConverter = new
RocketMQMessageConverter();
CompositeMessageConverter messageConverter =
(CompositeMessageConverter)rocketMQMessageConverter.getMessageConverter();
messageConverter.getConverters().add(0, protobufMessageConverter);
return rocketMQMessageConverter;
}
but an exception occured:
Caused by: java.lang.ClassCastException: class java.lang.String cannot be
cast to class [B (java.lang.String and [B are in module java.base of loader
'bootstrap')
at
org.springframework.messaging.converter.ProtobufMessageConverter.convertFromInternal(ProtobufMessageConverter.java:147)
