RocketMQ现在是发消息序列化取得MessageConverter不对,正常应该是这个的吧？

加这个试试
package icu.kevin.mq.rocketmq.config;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import org.apache.rocketmq.spring.support.RocketMQMessageConverter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.messaging.converter.CompositeMessageConverter;
import org.springframework.messaging.converter.MappingJackson2MessageConverter;
import org.springframework.messaging.converter.MessageConverter;

import java.util.List;

@Configuration
public class RocketMQEnhanceConfig {

/**
 * 解决RocketMQ Jackson不支持Java时间类型配置
 */
@Bean
@Primary
public RocketMQMessageConverter enhanceRocketMQMessageConverter(){
    RocketMQMessageConverter converter = new RocketMQMessageConverter();
    CompositeMessageConverter compositeMessageConverter = (CompositeMessageConverter) converter.getMessageConverter();
    List<MessageConverter> messageConverterList = compositeMessageConverter.getConverters();

    for (MessageConverter messageConverter : messageConverterList) {
        if(messageConverter instanceof MappingJackson2MessageConverter){
            MappingJackson2MessageConverter jackson2MessageConverter = (MappingJackson2MessageConverter) messageConverter;
            ObjectMapper objectMapper = jackson2MessageConverter.getObjectMapper();
            objectMapper.registerModules(new JavaTimeModule());
        }
    }
    return converter;
}

}
