The code use new MappingJackson2MessageConverter(), so it can't use my custom MappingJackson2MessageConverter.

package org.apache.rocketmq.spring.support;

import java.util.ArrayList;
import java.util.List;
import org.springframework.messaging.converter.ByteArrayMessageConverter;
import org.springframework.messaging.converter.CompositeMessageConverter;
import org.springframework.messaging.converter.ContentTypeResolver;
import org.springframework.messaging.converter.MappingJackson2MessageConverter;
import org.springframework.messaging.converter.MessageConverter;
import org.springframework.messaging.converter.StringMessageConverter;
import org.springframework.util.ClassUtils;

public class RocketMQMessageConverter {
    private static final boolean JACKSON_PRESENT;
    private static final boolean FASTJSON_PRESENT;
    private final CompositeMessageConverter messageConverter;

    public RocketMQMessageConverter() {
        List<MessageConverter> messageConverters = new ArrayList();
        ByteArrayMessageConverter byteArrayMessageConverter = new ByteArrayMessageConverter();
        byteArrayMessageConverter.setContentTypeResolver((ContentTypeResolver)null);
        messageConverters.add(byteArrayMessageConverter);
        messageConverters.add(new StringMessageConverter());
        if (JACKSON_PRESENT) {
            messageConverters.add(new MappingJackson2MessageConverter());
        }

        if (FASTJSON_PRESENT) {
            try {
                messageConverters.add((MessageConverter)ClassUtils.forName("com.alibaba.fastjson.support.spring.messaging.MappingFastJsonMessageConverter", ClassUtils.getDefaultClassLoader()).newInstance());
            } catch (IllegalAccessException | InstantiationException | ClassNotFoundException var4) {
            }
        }

        this.messageConverter = new CompositeMessageConverter(messageConverters);
    }

    public MessageConverter getMessageConverter() {
        return this.messageConverter;
    }

    static {
        ClassLoader classLoader = RocketMQMessageConverter.class.getClassLoader();
        JACKSON_PRESENT = ClassUtils.isPresent("com.fasterxml.jackson.databind.ObjectMapper", classLoader) && ClassUtils.isPresent("com.fasterxml.jackson.core.JsonGenerator", classLoader);
        FASTJSON_PRESENT = ClassUtils.isPresent("com.alibaba.fastjson.JSON", classLoader) && ClassUtils.isPresent("com.alibaba.fastjson.support.config.FastJsonConfig", classLoader);
    }
}
